摘要:A one-pot process for the synthesis of isocyanates, polyisocyanates or mixtures thereof which includes the steps of:n i. preparing a mixture comprising an amine, an alcohol, an oxygen-containing gas, carbon monoxide, a metal complex catalyst selected from the group consisting of macrocyclic complex catalysts and cobalt Shiff base catalysts; and a solvent selected from the group consisting of aliphatic or aromatic halocarbons, perhalogenated alcohols, halogenated ethers, halogenated ketones, perfluorinated hydrocarbons, polymers of chlorotrifluoroethylene having the formula —(CF 2 —CFCl) n wherein n is between 2 and 10, and mixtures thereof; ii. subjecting the resulting mixture to a first heating under pressure; iii. cooling and depressurizing the mixture resulting from the previous step; and iv. subjecting the mixture of the previous step to a second heating to separate out the isocyanate product from the mixture.

摘要:Provided are a solid catalyst which gives a cyclic carbonate at a high yield and a high selectivity, which is stable and which may be readily separated after reaction; and a method of industrially advantageous, inexpensive and safe production of a cyclic carbonate by the use of the catalyst. The catalyst contains an inorganic solid substance having a surface modified with an ionic substance containing a Group 15 element; or contains an ionic substance containing a Group 15 element, and an inorganic solid substance. The modifying group for surface modification of an inorganic solid substance is an ionic substance containing a Group 15 element. The ionic substance containing a Group 15 element is at least one substance selected from organic phosphonium salts, organic ammonium salts, organic arsonium salts and organic antimonium salts.
