摘要
Abstract
The reaction of isooctanol with phosphorus trichloride to produce diisooctyl phosphite(ester)is an efficient preparation method.However,due to the large amount of HCl generated during the reaction,the removal method of HCl removal would greatly affect the quality of the ester.In this study,three meth-ods for removing HCl were investigated,including liquid alkali neutralization,gas-phase ammonia neu-tralization,and distillation.The effects of different acid removal methods on product quality were investi-gated using NMR H and P-spectroscopy,and gas chromatography.Furthermore,the process and possi-bility of industrialization were also discussed.关键词
