3-芳基苯并呋喃酮类化合物的精制工艺研究

摘要

对3-芳基苯并呋喃酮衍生物3-(3,4-二甲基苯基)-5,7-二叔丁基-3-氢-苯并呋喃-2-酮(SHY-1)的精制工艺进行了研究.在较佳的精制工艺条件下,精制产品的纯度可达99.90%,收率可达70.20%;其在BOPP的应用效果显示,三元复合抗氧剂组成配比SHY-1为15%、1010为42.5%、并且168为42.5%的YJK-101-1#抗氧化效果最为突出.%The purification process and application of 3-(3,4-dimethylphenyl)-5,7-di-tert-butyl-methyl-3H-benzofuran-2-one(SHY-1)was researched. The purification process conditions were optimized,the purity of the product was 99.90%and the yield of the product was 70.20%under optimum purification condition. Its application effect on BOPP showed that when the ternary composite antioxidant ratio is 15%for YJK-101-1#,42.5%for SHY-1,42.5%for 1010 and 42.5%for 168,its anti-oxidation effect is most prominent.
