Non Technical Summary
The purpose of this proposal is to develop an environmentally friendly, non-toxic, and novel additive technology to replace emerging pollutant contaminants benzoyl triazoles and tolyl triazoles across multiple market sectors, including lubricants, but also extending to aircraft deicer fluids and in numerous other commercial industries where metal surfaces are exposed to corroding agents, without compromising on their performance.These additives are added to consumer products to reduce the corrosion of non-ferrous metals (such as aluminum, copper, nickel, tin, and copper alloys like brass and bronze), and notably in other industrial products, including aircraft deicing fluids (ADFs). While the USA's EPA has kept these compounds under the subject of a test rule, the Canadian government has passed a draft rule in 2021 on benzotriazole and tolyl triazole compounds included among fifteen chemicals categorized as substances of ecological risk. These varying regulations and restrictions in major economies allow us to conclude that these additives are emerging pollutants. It is more evident now that the chemical fate of emergent pollutants is not suitable for the aquatic community and the environment. It is a societal obligation to find safer corrosion inhibitor alternatives, preferably through new molecular designs based on eco-friendly and biobased routes.This proposal includes novel molecular engineering, design, optimization, and synthesis using biobased products to develop and test using industry-standard test methods to optimize and commercialize the safer products to replace the above-mentioned emerging pollutants. Industry-standard test methods include American Standards Testing Materials (ASTM) D130, ASTM D 665, and the Organisation for Economic Co-operation and Development (OECD) 201,202, and 203.

Goals / Objectives
This project aims to develop an environmentally friendly, performance-competitive, novel additive technology to replace emerging pollutant contaminants benzoyl triazoles and tolyl triazoles across multiple market sectors, including lubricants and airplane deicer fluids (ADFs), and numerous other commercial industries. The occurrence of previously undetected chemicals, which are termed "emerging contaminants," is now frequently reported. Examples include wastewaters, receiving waters, and consumer products such as washing detergents and bleaching agents. Corrosion inhibitors have been in consumer products for multiple decades. The corrosion inhibitors identified as emerging contaminants are benzotriazole, tolyl triazole, and derivatives. While these are added to consumer products to reduce the corrosion of non-ferrous metals (such as aluminum, copper, nickel, tin, and copper alloys like brass and bronze), these chemicals are notably in other industrial products, including aircraft deicing fluids (ADFs).Lubricants are integral for tools and equipment across all major industrial sectors. Commercial corrosion inhibitors, benzotriazole, and tolyl triazole additives (and their derivatives) used in lubricants have notable adverse effects on the environment. These harmful substances can enter the environment directly when lubricants contact water, soil, or air, via leakage or spillage from industrial equipment, ships, automobiles, engines, earth moving equipment, drilling, metalworking fluids, etc. Environmental issues like toxicityand biodegradability negatively impact corrosion inhibitors' global market growth?.Precisely, environmental risks force customers to seek more environmentally friendly products, while some products are subject to restrictions by government agencies in the USA and other countries. Thus, there is an urgent need to replace these harmful compounds with more environmentally friendly and sustainable alternatives without sacrificing performance. Polnox seeks to seize this opportunity by developing a new and novel compound to replace these emergent pollutants. We plan to use safer, renewably resourced, biobased biochemicals to engineer a novel, high-performing, non-toxic corrosion inhibitor additive targeted explicitly in the formulation of lubricants suitable to use in agriculture equipment and aircraft deicing fluids during phase I and Phase II period.
Project Methods
Plan to developand implement efficient, safer, scalable chemical synthetic routes during this project. This is an essential component to go from laboratory scale (~gram)- laboratory scaleup (~lb)- pilot-scale (~100lbs-200lbs)- production (~tons). The process developed needs to be simple and easily adaptable in a typical production facility. The clever aspect of this kind of work is to create a methodology with a minimal number of synthetic steps to reduce the cost of making with a high yield. This is an essential step to reduce manufacturing costs to compete with existing generic products in the market, which are low priced to start with. Price-performance needs to be optimized yet provide societal benefits of the new products and technology. This requires a systematic approach and efforts to develop and implement scalable steps starting from thevery beginning.

Outputs
Target Audience:The goal of this proposal is to develop an environmentally friendly, non-toxic, and novel additive technology to replace emerging pollutant contaminants benzoyl triazoles and tolyl triazoles across multiple market sectors, including lubricants, but also extending to aircraft deicer fluids and in numerous other commercial industries where metal surfaces are exposed to corroding agents, without compromising on their performance Changes/Problems: Nothing Reported What opportunities for training and professional development has the project provided? Nothing Reported How have the results been disseminated to communities of interest?Not yet. These are innovative products and these are potential candidates for patent application filing. After careful assessment of their market analysis and patent application filing, the results will be disseminated to lubricant professionals through presentations in the national meetings. What do you plan to do during the next reporting period to accomplish the goals? Nothing Reported

Impacts
What was accomplished under these goals? Two products were designed, synthesized, and tested for their dual properties namely corrosion inhibition (for copper, aluminum, non-ferrous metals)and rust inhibition (for iron), using ASTM test methods. One of the two products was designed for lubricants and the other one for aircraft deicer fluid (ADF).Their toxicity properties were tested using OECD test methods. The biodegradability of these products was assessed usingthe EPA software program. All these tests and computation analyses indicate both product performances are comparable to products in commerce but added features include these products are biobased and biodegradable, non-toxic, and meet the requirements of EPA and EU's REACH compliance rules.

    Outputs
    Target Audience:Corrosion is a global problem spanning sectors from infrastructure and transportation to production and manufacturing and having a global economic impact in both developed and developing countries. Materials and corrosion control technologies are necessary to mitigate safety issues arising from product failure, repairs, and replacements. Corrosion inhibitors, which reduce or suppress metal corrosion, are a class of environmentally dangerous additives commonly used in lubricants, aircraft deicer fluids (ADFs), and many other applications. Polnox's R&D focus is on the development of biobased and environmentally friendly, novel corrosion inhibitor additive technology to replace the emerging contaminants benzoyl triazoles and tolyl triazoles across multiple market sectors, including lubricants, airplane deicer fluids, paints, and numerous other commercial industries. During this period, we refined the molecular design of the proposed compound and synthesized it using starting materialsderived from renewable resources, namely from plants. Experimental samples synthesized are meant to replace toxic corrosion inhibitors likebenzoyl triazoles and tolyl triazolesused in lubricants and other industries. These experimental samples were also tested using international standard methods in the lubricant industry. The hallmark of our design of these molecules is that the biobased experimental compounds suppress iron corrosion (ferrous materials) and copper corrosion (nonferrous materials, including aluminum). Our combination allows formulators not to use two compoundsto mitigate corrosion from ferrous and nonferrous materials. The benefits include (a) cost savings, pay for one compound and not for two compounds, (b) the product is safe and non-toxic, and, most importantly, (c) allowing chemical use reduction efficiency (CURE) in commerce. Our test data on our biobased corrosion inhibitor sample using ASTM D 130 (for copper corrosion testing) and ASTM D 665B (for rust testing)methodsshows the performance of the compounds is better compared to widely used petroleum-basedbenzoyl triazoles and tolyl triazoles used in commerce (same treat level). The preliminary cost estimate of our biobased compound shows that it is inexpensive compared to the cost of the two compounds used for mitigating copper corrosion and iron rusttoday. Development of Corrosion Inhibition for Aircraft Deicer Fluid. We have just started working on the synthesis and optimization of the compound. The requirement for this compound is that it needs to be water-soluble. The compounds discussed for lubricant oils are not suitable simply because they are not water-soluble. Our efforts focus on designing and synthesizing water-soluble corrosion inhibitors for aircraft deicer fluids. Then we will test its efficacy for inhibiting aluminum corrosion using the ASTM F483 method. In January 2023, we initiated our efforts by talking to potential customers about our technology-based products. A total of three companies, one based in France and two in the US., have shown interest. One company has already interested in receiving our compound for their evaluation. This development efforts and optimization work will continue in the no-cost extension period of Phase I and Phase II if awarded. Changes/Problems:Our work's evolution of molecular design and optimization to meet the targeted results is natural. We do not see this as a significant change in approach. This approach is necessary for R&D to progress to the level of outcome expectations. What opportunities for training and professional development has the project provided?How to be innovative and creative in product devlopment work based on new technologies needed for the project.. How have the results been disseminated to communities of interest?Mostly talking to potential companies in general terms and under non-disclosure agreements. What do you plan to do during the next reporting period to accomplish the goals?We are excited about our findings and results. Work on the biobased corrosion inhibitors to use in aircraft deicer fluids(ADFs)

    Impacts
