摘要
采用常规的中和水洗工艺无法降低偏苯三酸三辛酯 (TOTM)产品酸值 ;酯化反应的彻底进行酸值下降也很有限 ;采用碱的乙醇溶液可以有效降低产品酸值。
If TOTM is neutralized & washed with normal process,its acid-value is unable to be decreased,Though the esterification is complete,but its acid-value is decreased within limits.If TOTM is neutralized & washed with alkaline alcohol solution,then its acid-value will be come down validly.
