| Abstract: | The high-boiling components of cron polyols in industry was analyzed and determined by GC/MS,22 peaks were isolated,and 14 compounds were identified.The main chemical components were long-chain diol(38.43%) and loop-chain diol(57.43%).Separation of high-boiling components of corn polyols by reduced pressure distillation and molecular distillation were investigated.Resultes showed that isolating the similar groups could be achieved by reduced pressure distillation and molecular distillation methods. |
