【摘要】 在对抗氧化剂HP136结构进行分析的基础上,设计并合成一系列HP136衍生物,旨在筛选出新的碳自由基捕获剂.通过对其黄度测试和熔流指数等性能研究发现,1,1-二芳基乙酰胺型化合物的抗氧化性和颜色变化都接近HP136,其中2-(3,5-二叔丁基-2-羟基苯基)-N-烯丙基-2-苯基乙酰胺(2d)具有与HP136相当的抗氧化性能,具有较好的应用前景.更多还原

【Abstract】 HP136 is a free radical scavenging anti-oxidant invented by Ciba Specialty Chemicals,which is widely used in the process of polyolefin production.However,recently it has receded from the market probably because of its potential toxicity to human bodies.In order to develop a novel anti-oxidant with both high effectivity and low toxicity,a series of HP136 derivatives were synthesized.The melt flow indexes and yellowness indexes showed that the antio-xidant ability and color change of 1,1-diaryl-acetamides were both similar with HP136.Among them,2-(3,5-di-tert-butyl-2-hydroxyphenyl)-N-allyl-2-phenyl acetamide(2d) had an anti-oxidant activity as high as HP136.We believe that it will have a prosperous future for application in the industry.更多还原
