摘　　要：以4,4’-二环己基甲烷二异氰酸酯(H12MDI)和正丁醇为原料合成了4,4’-二环己基甲烷二氨基甲酸丁酯(H12MDU),得到两种固体产物(A和B);分别利用熔点测定、红外光谱、元素分析、核磁共振和质谱等技术对产物结构进行分析表征。结果表明,固体A和B均为目标产物H12MDU。固体A为反-反结构H12MDU,固体B为H12MDU不同异构体的混合物,不仅含有反-反结构H12MDU,并且至少含有顺-反和顺-顺结构H12MDU中的一种。Bis（4-butoxycarbonylaminocyclohexyl）methane（H12MDU） was prepared using dicyclohexylmethane-4,4＇-diisocyanate and 1-butanol as raw materials and two solid products A and B were obtained.The structures of the two solid products were characterized separately by melting point measurement,infrared spectroscopy,elemental analysis,NMR spectrum analysis and mass spectrum analysis.The results show that both A and B are the target products H12MDU.The solid A is trans-trans-H12MDU while the solid B is a mixture including trans-trans-H12MDU and at least one of cis-trans-H12MDU and cis-cis-H12MDU.
