The broader impact/commercial potential of this Small Business Innovation Research Phase II project is to help protect the environment by replacing existing toxic and environmentally-hazardous corrosion inhibitors used as lubricant additives with more eco-friendly alternatives. Release of lubricants (for example from loss during use, improper disposal of waste lubricants, accidental spillage, or off-shore drilling) has the potential to cause damage to the environment. Awareness of the toxic nature of current lubricant additives is a driver to develop new technologies for more environmentally friendly products. This project addresses the development of novel, environmentally friendly corrosion inhibitor lubricant additives. Besides the environmental benefits of the new technology, the lubricant industry may also benefit by expansion into environmentally sensitive market sectors (for example, marine lubricants used on ships) through the use of safer and less toxic additives. The new products also utilize non-petroleum based raw materials from renewable and sustainable resources, thus reducing dependence on petroleum. Apart from being non-toxic and environmentally friendly, the proposed products are also expected to be more effective inhibitors as compared to the products currently used in the market.The objectives of this Phase II research project are to design and develop environmentally friendly corrosion inhibitors providing high performance while meeting the eco-toxicological requirements of environmentally acceptable lubricants (EAL), including bio-lubricants. The use of corrosion inhibitors in lubricants is essential to protect metal surfaces. Unfortunately, many commercial corrosion inhibitors present issues with aquatic toxicity, persistence in the environment, and/or bioaccumulation that render them unacceptable for use in EAL or bio-lubricants. Awareness of the eco- toxicological problems of current inhibitors and the implementation of new regulations mandating the use of EAL in certain applications (e.g. marine lubricants) has created an urgent need in the market to replace existing products and the opportunity to develop new technologies for corrosion inhibition. This proposal addresses the key steps involved in the product development of corrosion inhibitors for biolubricants; namely (a) molecular design optimization, (b) cost-effective process scale up, (c) preparation of pound scale of lead products in the laboratory set-up; as identified in Phase I, (c) assessment of eco-toxicological properties using industry standard OECD/ASTM test methods and structure activity relationship (SAR) calculations, and (d) product storage stability testing.

这项小型企业创新研究阶段II阶段项目的更广泛的影响/商业潜力是通过更换现有的有毒和环保腐蚀抑制剂来帮助保护环境。释放润滑剂（例如，使用过程中的损失，废物润滑剂的处理不当，意外溢出或离岸钻探）有可能造成对环境的损害。对当前润滑剂添加剂的毒性性质的认识是开发新技术的驱动力。该项目涉及新颖的环保腐蚀抑制剂润滑剂添加剂的开发。除了新技术的环境益处外，润滑油行业还可以通过使用更安全和毒性较小的添加剂来扩展到环境敏感的市场领域（例如，在船上使用的海洋润滑剂）受益。这些新产品还利用可再生和可持续资源的非甲基原料，从而降低了对石油的依赖。除了无毒和环保的友好外，与市场上当前使用的产品相比，提议的产品还有望更有效。该II阶段研究项目的目标是设计和开发具有高性能的环保腐蚀抑制剂，同时满足环境可接受的润滑剂（包括生物素），包括环境可接受的润滑剂。在润滑剂中使用腐蚀抑制剂对于保护金属表面至关重要。不幸的是，许多商业腐蚀抑制剂呈现出水生毒性，环境持续性和/或生物蓄积的问题，这些问题使它们无法接受，可用于EAL或生物润滑剂。对当前抑制剂的生态毒理问题的认识以及实施新法规要求在某些应用中使用EAL（例如，海洋润滑剂）在市场上迫切需要替代现有产品，并有机会开发新技术以抑制腐蚀。该提案介绍了生物润滑剂腐蚀抑制剂产品开发的关键步骤；即（a）分子设计优化，（b）成本效益的过程规模，（c）在实验室设置中制备铅产品磅量表；如第一阶段所述，（c）使用行业标准OECD/ASTM测试方法和结构活动关系（SAR）计算以及（d）产品存储稳定性测试评估生态毒理学特性。
