Hydrocarbons - raw or transformed into industrial chemicals or consumer products - are highly susceptible to oxidative deterioration, a process mediated by free radicals. As such, radical-trapping antioxidants comprise some of the more important chemical additives to virtually all petroleum-derived materials, from oils, fuels and rubber to plastics, cosmetics and consumer products. The vast majority of the additives used today were developed over half a century ago as unsuccessful efforts to develop novel chemical scaffolds with superior reactivity, but good stability, has lead to stagnation in the development of new technologies. Recent NSERC-funded research on the chemistry of radical-trapping antioxidants in the applicant's laboratories has lead to the conception of a new class of antioxidant compounds that have exciting commercial potential. Herein we propose to undertake a collaborative project with BASF Canada to help develop this technology into a product that could enhance the longevity of multiple BASF products produced in Canada, as well as Canadian petroleum-derived products which rely on BASF additives to ensure their longevity.

碳氢化合物--无论是未加工的还是转化为工业化学品或消费品的--都非常容易氧化变质，这是一个由自由基介导的过程。因此，自由基捕获抗氧化剂包括几乎所有石油衍生材料的一些更重要的化学添加剂，从石油，燃料和橡胶到塑料，化妆品和消费品。当今使用的绝大多数添加剂是在半个多世纪前开发的，因为开发具有上级反应性但具有良好稳定性的新型化学支架的不成功的努力导致了新技术开发的停滞。最近NSERC资助的在申请人的实验室中进行的关于自由基捕获抗氧化剂的化学的研究导致了一类具有令人兴奋的商业潜力的新型抗氧化剂化合物的概念。在此，我们建议与巴斯夫加拿大公司开展一个合作项目，帮助将该技术开发成一种产品，可以提高在加拿大生产的多种巴斯夫产品的寿命，以及依赖巴斯夫添加剂确保其寿命的加拿大石油衍生产品。
