摘要
用毛细管色谱柱XE-60对甲苯二异氰酸酯[TDI(80/20)]进行分离,测定TDI异构比。此色谱柱能够将TDI组份分离,但开始时有少量吸附,吸附平衡后,能够比较准确的测定TDI(80/20)异构比,完全具备了准确定量分析的要求。
To determin the isomerous ratio of toluene diisocyanate（TDI） by separating TDI（80/20） with XE-60 capillary column.This chromatographic column could separate TDI component,but there was a little adsorption during preliminary period.After balance of adsorption it could determine the isomerous ratio of TDI exactly.
