PROCESS FOR TRANSFORMING ACID ANHYDRIDES TO CORRESPONDING ALKYLIDENES DIESTERS IN THE PRESENCE OF COBALT-CARBONYL AS CATALYST |
| abstract |
The invention describes a catalytic process for converting acid anhydride into corresponding alkylidene diesters. Carboxylic acid anhydrides are reacted with hydrogen in the presence of a cobalt-carbonyl to obtain corresponding alkylidene diesters in high yield and with similar ratios of these diesters to the co-produced carboxylic acid. of theory. The process applies in particular to the transformation of acetic anhydride into ethylidene diacetate which is a basic chemical intermediate in organic synthesis. |
