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-钇,并进行了动力学研究。

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,从巯基乙异辛酯的底残液中回收异辛醇,异辛醇产品含量达99%以上,产品成本低,经济效益。
