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.

这个小企业创新研究第二阶段项目的更广泛的影响/商业潜力是通过用更环保的替代品取代用作润滑油添加剂的现有有毒和对环境有害的缓蚀剂来帮助保护环境。润滑剂的释放(例如使用过程中的损失、废润滑剂的不当处置、意外泄漏或近海钻井)有可能对环境造成破坏。对当前润滑油添加剂有毒性质的认识是开发更环保产品的新技术的驱动力。该项目致力于开发新型、环保的防腐润滑剂添加剂。除了新技术的环境效益外，润滑油行业还可以通过使用更安全、毒性更低的添加剂，扩展到对环境敏感的市场部门(例如，船舶上使用的船用润滑油)，从而受益。新产品还利用了来自可再生和可持续资源的非石油原料，从而减少了对石油的依赖。除了无毒和环保外，拟议产品还有望成为比目前市场上使用的产品更有效的缓蚀剂。这项第二阶段研究计划的目标是设计和开发具有高性能的环保型缓蚀剂，同时满足环境可接受润滑剂(包括生物润滑剂)的生态毒理学要求。在润滑剂中使用缓蚀剂对于保护金属表面是必不可少的。不幸的是，许多商业缓蚀剂存在水毒性、在环境中的持久性和/或生物积累的问题，这使得它们不能用于EAL或生物润滑剂。对目前缓蚀剂的生态毒理问题的认识，以及要求在某些应用(如船用润滑剂)中使用EAL的新法规的实施，在市场上产生了取代现有产品的迫切需求，并创造了开发新的缓蚀技术的机会。该提案涉及生物清洗剂缓蚀剂产品开发的关键步骤，即(A)分子设计优化，(B)具有成本效益的工艺放大，(C)在实验室装置中制备磅规模的铅产品，如第一阶段所确定的，(C)使用行业标准OECD/ASTM测试方法和结构活性关系(SAR)计算评估生态毒理特性，以及(D)产品储存稳定性测试。
