PROCESS FOR THE PRODUCTION OF CYCLIC THIOCARBONATES AND COMPOUNDS OBTAINED THEREBY

摘要

The present invention relates to the production of cyclic thiocarbonates by reacting a thioglycol or a hydroxydisulphide with carbon oxide in presence of transition metals or transition metal compounds. The thiocarbonates are very important products from a practical point of view since some of them are precursors of the alkylene sulphides or episulphides which are widely employed in the production of polymers with peculiar properties.
