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.

该小型企业创新研究 (SBIR) 第二阶段项目提议基于 Polnox 专有的“每分子双型部分”(DT-mPM) 技术开发和商业化具有成本效益的高性能大分子抗氧化剂，用于可持续替代生物油。氧化稳定性是工业生物油的一个关键问题。这些源自生物资源的油与源自化石燃料的油相比稳定性较差。 特别是，源自植物的多不饱和脂肪酸的燃料和润滑剂特别容易发生严重氧化。第一阶段已证明，与最先进的商业抗氧化剂相比，DT-mPM 抗氧化剂在对抗这些生物油的降解方面明显更有效。目前最先进的商业抗氧化剂无法应对植物源生物油带来的挑战。目前的抗氧化剂是为了保护石油润滑剂而开发的，根本无法解决生物润滑剂带来的稳定性问题。 该提案解决了生物润滑剂抗氧化剂产品开发中涉及的关键步骤；即，（a）分子设计优化，（b）具有成本效益的工艺规模扩大，（c）第一阶段确定的磅级铅抗氧化剂的制备，以及（d）产品储存稳定性。该项目更广泛的影响/商业潜力是通过减少空气、土壤、水和生态系统的污染，在减少国家对外国石油的依赖和提供更清洁的环境方面发挥重要作用。增加使用生物润滑剂带来的社会效益包括减少环境污染的可能性（例如，使用过程中的损失或废润滑剂处置不当、工业使用或海上钻井过程中的意外石油泄漏）以及减少对进口石油作为原材料的依赖。 然而，由于油是从可再生替代能源中开发出来的，因此存在一些需要解决的固有问题：(1) 热氧化稳定性，以及 (2) 倾点特性。 通过开发和商业化新型高性能抗氧化剂来解决生物油的热氧化稳定性问题，这将能够生产可生物降解且对环境安全的更高质量的替代油。
