非光气法合成二苯基甲烷二异氰酸酯的研究进展

摘要

综述了国内外非光气法(如三光气法、酯交换法以及氨基甲酸酯热分解法)合成二苯基甲烷二异氰酸酯(MDI)的研究进展.参考文献36篇.%Research progress on the synthesis of diphenylmethane-4,4'-diisocyanate(MDI) by the non-phosgene method, which were triphosgene, transesterification and especially ammonium carba-mate thermal decomposition, were reviewed with 36 references.
