| 摘 要： | 六亚甲基二异氰酸酯（HDI）是聚氨酯合成的重要的原料之一。对六亚甲基二氨基甲酸甲酯（HDU）热分解合成六戚甲基二异氰酸酯（HDI）进行了研究，考察了催化剂、反应温度、反应时间、物料浓度、催化剂甩量等对反应的影响。优化后反应条件为：以HSFE为催化剂，反应温度260℃，催化剂用量为溶剂质量的0．30％，HDU浓度7．50％。此条件下反应35min，HDI收率为66．51％。

| Abstract: | The synthesis of hexamethylene diisocyanate（HDI） from thermal decomposition of hexamethylene diurethane was studied using metal/metallic oxide as catalyst. The effects of catalyst types, reaction temperature, catalyst amount, HDU concentration, reaction time were investigated. Under optimal conditions： 0.30 % HSFE as catalyst, 7.50 % HDU, reaction temperature 260 ℃ and reaction time 35 min. As a result, the yield of HDI reached 66.51%. |
