英语翻译The application of modified vegetable oils in the chemic

The application of modified vegetable oils in the chemical industry is becoming more and more important because of their availability from renewable resources。 Epoxidized vegetable oils play an important role as building blocks for the preparation of chemical intermediates that are the basis for a wide variety of consumer products [1]。 Epoxidized oils can be used as PVC-plasticizers and stabilizers, reactive diluents for paints, intermediates in the production of polyurethane-polyols, as well as components of lubricants and adhesives [2]。
在化学工业中,采用改性的植物油正在变得越来越重要,因为它们可以从可更新的来源获得。环氧化的植物油作为用于制备各种消费产品基础的化学中间体的基本成分,起着重要的作用【1】。环氧化的油可以用作聚氯乙烯的增塑剂和稳定剂、油漆的反应性稀释剂、生产聚氨酯多元醇的中间体、以及润滑剂和黏结剂的成分【2】。
The catalytic epoxidation of oleochemicals has been the subject of many academic and industrial investigations [3,4]。However, the only commercial source of epoxidized oils is the Prileshajev reaction which uses short chain percarboxylic acids[5]。 Other methods for the epoxidation of unsaturated fatty compounds include the use of dioxiranes [6], the generation of peracids from aldehydes and molecular oxygen [7], chemo- enzymatic ‘‘self-epoxidation’’ catalyzed by immobilized Novozym 4351 [8], and transition metal catalyzed C - C epoxidations using alkylhydroperoxides [9]。
油脂化学品的催化环氧化已成为很多学术界和产业界研究的主题【3,4】。然而,环氧化油的唯一商品来源是Prileshajev反应,它采用短链的过羧酸【5】。不饱和脂肪化合物的其他环氧化方法包括采用过氧化酮【6】,从醛类和分子氧产生过酸【7】,用固定化的Novozym435®催化的化学酶法“自我环氧化”【8】,以及采用烷基过氧化氢（alkylhydroperoxides）的、过渡金属催化的C-C环氧化【9】。
