saponifying

The study on technical process and kinetics of PVC heat steadilizer yttrium stearate by saponifying method was carried out.

采用皂化法制备了PVC热稳定剂-硬脂酸钇,并进行了动究。

Saponifying hydrolysis and oxidation process was used to recover isooctyl alcohol from the relic after vapouring、quality of product is above 99%,and the cost is lower,so the technology is gainful.

本试验采用皂化氧化法,从巯基乙酸异辛酯的底残液中回收异辛醇,异辛醇含量可达99%以上,本低,经济效益可观。
