抗氧剂300的合成与应用
SYNTHESIS AND APPLICATION OF ANTIOXIDANT 300
【摘要】 抗氧剂300即4,4′-硫代双(3-甲基-6-叔丁基苯酚)是1种非污染性高效主抗氧剂。本文介绍了从叔丁醇脱水制异丁烯,异丁烯与间甲酚经烷基化制3-甲基-6-叔丁基苯酚,再与二氯化硫缩合制得抗氧剂300的合成工艺,并介绍了抗氧剂300在塑料、橡胶中的应用效果。
【Abstract】 Antioxidant 300,4.4’-thiobis (3-methyl-6-tert-butyl-phenol), is a nonstaining and effective antioxidant. A synthesizing process was developed by co.ndensation of 3-methyl-6-tert-butyl-phenol (Ⅰ) with sulfur dichloride. I was prepared by alkylation of m-cresol with isobutene dehydrated from tert-butyl alcohol. The application of antioxidant 300 in plastics and rubber was also introduced.
