saponify

A new process was proposed to saponify the crude lanolin in alkaliaqueous solution with the addition of ethanol and then to separate the product by converting the sodium soap into calcium soap.

以粗羊毛脂为原料,提出了一条羊毛脂在碱溶液添加助剂乙醇皂化及其用钙皂转化来分离产物的工艺路线。

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,从巯基乙酸异辛酯的釜底残液异辛醇,异辛醇产品含量可达99%以上,产品成本低,经济效益可观。
