This Small Business Innovation Research (SBIR) Phase II project proposes to develop and commercialize cost-effective high performance macromolecular antioxidants based on Polnox's proprietary "dual type moiety per molecule" (DT-mPM) technology for sustainable-alternate bio-oils. Oxidative stability presents a key issue for industrial bio-oils. These oils, which are derived from bio-resources, have inferior stability compared those derived from fossil fuels. In particular, fuels and lubricants derived from plant-based polyunsaturated fatty acids are especially prone to severe oxidation. It has been demonstrated in Phase I that the DT-mPM antioxidants are significantly more effective in combating degradation of these bio-oils vs. state-of-the-art commercial antioxidants. The current, state-of-the-art, commercial antioxidants do not meet the challenges posed by plant-derived bio-oils. Current antioxidants were developed to protect petroleum lubricants and are simply not capable of meeting the stability issues posed by bio-lubricants. This proposal addresses the key steps involved in the product development of antioxidants for bio-lubricants; namely, (a) molecular design optimization, (b) cost-effective process scale up, (c) preparation of pound scale of lead antioxidants identified in Phase I, and (d) product storage stability. The broader impact/commercial potential of this project is to play an important role in reducing the nation's dependence on foreign oil and providing a cleaner environment by reducing the pollution of air, soil, water, and the eco-system. Societal benefits from the increased use of bio-lubricants include less potential for environmental pollution (e.g., from loss during use or improper disposal of waste lubricants, accidental oil spillage during industrial use, or off-shore drilling) as well as reduced dependence on imported petroleum as a raw material. However, as oils are developed from renewable alternate energy resources, there are some inherent issues to be addressed: (1) thermo-oxidative stability, and (2) pour-point properties. By addressing the thermo-oxidative stability problem of bio-oils through the development and commercialization of new high performance antioxidants, this will enable the production of higher quality alternate oils that are biodegradable and environmentally safe.

这项小型企业创新研究（SBIR）II期项目提议基于波尔诺克斯专有的“双型部分分子”（DT-MPM）技术开发和商业化具有成本效益的高性能高性分子抗氧化剂，以用于可持续的生物油。氧化稳定性提出了工业生物油的关键问题。这些来自生物资源的油具有较低的稳定性，比较了化石燃料的稳定性。 特别是，源自植物性多不饱和脂肪酸的燃料和润滑剂特别容易被严重氧化。在第一阶段证明，DT-MPM抗氧化剂在对抗这些生物油与最先进的商业抗氧化剂的降解方面更有效期。当前的，最先进的商业抗氧化剂不符合植物衍生的生物油带来的挑战。开发了当前的抗氧化剂来保护石油润滑剂，并且根本无法满足生物润滑剂构成的稳定性问题。 该提案解决了生物润滑剂抗氧化剂产品开发涉及的关键步骤；即，（a）分子设计优化，（b）成本效益的过程规模，（c）制备在I期中确定的铅抗氧化剂的磅尺度，以及（d）产品存储稳定性。该项目的更广泛的影响/商业潜力是通过减少空气，土壤，水和生态系统的污染来减少国家对外国石油的依赖并提供更清洁的环境发挥重要作用。增加使用生物润滑剂所带来的社会利益包括较小的环境污染潜力（例如，使用期间的损失或废物润滑剂的处理不当，工业使用期间的意外溢油或近海钻探）以及降低对进口石油作为原材料的依赖。 但是，随着油是从可再生替代能源开发的，需要解决一些固有的问题：（1）热氧化稳定性，以及（2）倒点性能。 通过通过新的高性能抗氧化剂的开发和商业化来解决生物油的热氧化稳定性问题，这将使能够生产可生物降解且在环境上安全的高质量替代油。
