高效液相色谱用于硫化烷基酚钙添加剂水解物的分离制备

Semi-Preparative Separation of the Hydrolysis Products of Vulcanized Calcium Alkylphenol by High Performance Liquid Chromatography

硫化烷基酚钙添加剂是一种性能优良的润滑油清净分散添加剂,它是由丙烯四聚物,S、CaO或Ca(OH)与对位烷基酚在乙二醇作促进剂条件下合成的复杂混合物,由于合成后R取代基的影响给剖析其组成带来很大困难。

The hydrolysis products of vulcanized calcium alkylphenol were separated by reversed-phase semi-preparative HPLC with ODS packing and methanol-ethyl acetate (70/30 by volume) mobile phase.
