Abstract
1,224,518. Carboxylic acid esters. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 10 Nov., 1969 [11 Nov., 1968], No. 53317/68. Heading C2C. Carboxylic esters are obtained by reacting an ether of formula R 1 -O-R 2 , wherein R 1 and R 2 represent the same or different organic radicals, with CO in the presence of H 2 O- containing liquid HF. The liquid HF preferably contains 0À1 to 5% H 2 O. Substantially pure CO or mixtures thereof with inert gases may be used. The process may be carried out batchwise or continuously. In the latter case the process comprises the steps of (a) introducing into a reactor liquid HF, the ether, CO and H 2 O; (b) separating an ester phase and a substantially ester-free phase from liquid reactor effluent; and (c) recycling at least part of the substantially ester-free phase formed in step (b) to the reactor in step (a). A schematic apparatus suitable for carrying out the process is described. An example is given for the preparation of methyl trimethylacetate.
