Abstract
Official abstract text for this publication.
An asymmetric chain carbonate can be produced in a single-step reaction comprising a step of reacting methyl nitrite, carbon monoxide, and 0.05-1.5 moles of an aliphatic alcohol having 2-6 carbon atoms or an alicyclic alcohol having 5-6 carbon atoms per one mole of methyl nitrile in a gaseous phase in the presence of a solid catalyst comprising a platinum group metal or a compound thereof placed on a support.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for producing an asymmetric chain carbonate consisting of a step of reacting methyl nitrite, carbon monoxide and 0.25-1 moles of a lower alcohol per one mole of methyl nitrite, the lower alcohol being selected from the group consisting of ethanol, in a gaseous phase in the presence of a solid catalyst comprising palladium chloride and cupric chloride placed on a support, wherein the produced asymmetric carbonate is selected from the group consisting of methyl ethyl carbonate, wherein the palladium chloride and cupric chloride are deposited on the support in an amount of 0.1 to 10 wt. % per the amount of the compound. 2. The method of claim 1 , wherein the support of the solid catalyst is a porous support. 3. The method of claim 2 , wherein the porous support comprises a material selected from the group consisting of carbon, alumina, silica, silica alumina, zeo-lite, and lithium aluminate having a spinel structure. 4. The method of claim 1 , wherein the reaction is performed under supply of hydrogen chloride in an amount of 0.01 to 1 mole per one mole of the platinum group metal in the catalyst.
