Non-phosgene route:catalytic carbonylation of amines to form unsymmetrical ureas
《National Science Review》2025年第1期2-3,共2页Shunji Xie Ye Wang 
The production of unsymmetrical ureas,which are widely used in the pharmaceutical field[1],still relies heavily on the multi-steps reaction of two different amines with extremely toxic phosgene as the carbonyl source,...

Non-phosgene synthesis of hexamethylene-1,6-diisocyanate from thermal decomposition of hexamethylene-1,6-dicarbamate over Zn–Co bimetallic supported ZSM-5 catalyst被引量：2
《Chinese Journal of Chemical Engineering》2019年第3期549-555,共7页Yan Cao Yafang Chi Ammar Muhammad Peng He liguo Wang Huiquan Li 
Supported by the National Natural Science Foundation of China(21476244,21406245);Transformational Technologies for Clean Energy and Demonstration,Strategic Priority Research Program of the Chinese Academy of Sciences,(XDA 21030600);the Youth Innovation Promotion Association CAS(2016046)
A non-phosgene route for the synthesis of hexamethylene-1,6-diisocyanate(HDI) was developed via catalytic decomposition of hexamethylene-1,6-dicarbamate(HDC) over Zn–Co bi-metallic supported ZSM-5 catalyst.The cataly...

Important Green Chemistry and Catalysis： Non-phosgene Syntheses of Isocyanates - Thermal Cracking Way被引量：5
《Chinese Journal of Chemistry》2017年第6期821-835,共15页Peixue Wang Shimin Liu Youquan Deng 
This work was supported by the National Natural Science Foundation of China （No. 21173240）.
Currently, industrial production of isocyanates, or diisocyanates in particular, has been exclusively based on phosgene processes. Phosgene is extremely toxic and large amounts of corrosive HC1 are produced as a side ...

A Novel Non-phosgene Process for the Synthesis of Methyl N-Phenyl Carbamate from Methanol and Phenylurea: Effect of Solvent and Catalyst
《Chinese Journal of Chemistry》2004年第8期782-786,共5页王心葵 闫世润 曹勇 范康年 贺鹤勇 亢茂青 彭少逸 
Project supported by the Science and Technology Ministry of China (No. 2001CCA02700).
A novel environmentally benign process for the synthesis of methyl N-phenyl carbamate (MPC) from methanol and phenylurea was studied. Effect of solvent and catalyst on the reaction behavior was investigated. The IR s...
