高相对分子质量受阻酚抗氧剂KY-1330的合成与应用

Synthesis and Application of Hindered Phenol Antioxidant KY-1330 with High Molecular Weight

介绍了高相对分子质量受阻酚抗氧剂KY-1330的特点、合成及应用。着重介绍了该抗氧剂在国内的研发、生产及应用情况。对现有的合成工艺路线进行了比较,认为2,6-二叔丁基苯酚加入多聚甲醛,再与均三甲苯缩合的二步法更适合于国内。

The characteristic, the synthesis and the application of hindered phenol antioxidant KY - 1330 with high molecular weight were reviewed in the paper. The stress was laid on the development, manufacture and application of the antioxidant in our country. The synthesis routes were introduced. The author considers two - stage process （ adding 2,6 - bitertiary butyl phenol and polyformaldehyde , then condensing with mesitylene ） to be more propitious to our country.
