| abstract | 524,086. Esters. CONSORTIUM FUR ELEKTROCHEMISCHE INDUSTRIE GES. Jan. 21, 1939, No. 2123. Convention date, Jan. 21, 1938. [Class 2 (iii)] Hydroxy carboxylic acid esters are prepared by the catalytic reduction of condensation products of formic esters with esters of acetic, alkylacetic or alkoxyacetic acid. The hydrogenation products are solvent and plasticizing agents and are converted by loss of water into vinyl compounds (acrylic esters and the like). In examples : (1) formic ethyl ester is condensed with ethyl acetate in the presence of sodium to form sodium formyl acetic ethyl ester which is reduced to hydracrylic ethyl ester, (2) formyl propionic ethyl ester is prepared from ethyl formate and ethyl propionate and reduced to α-methyl hydracrylic acid ethyl ester, (3) α- methoxy-#-hydroxy-acrylic acid methyl ester is prepared from methyl formate and methoxyacetic acid methyl ester and reduced to α-methoxy hydracrylic acid methyl ester, and (4) α-butoxy #-hydroxy acrilic acid butyl ester is prepared from butyl formate and butoxy acetic acid butyl ester and reduced to α-botuxy hydracrylic acid butyl ester. |
