摘要

Process for preparing carboxylic acids by hydrolysis, and more specifically a compound of the formula: ** (See formula) ** where R is a member selected from the group consisting of hydrogen, lower alkyl, lower haloalkyl, cycloalkyl, cycloalkylalkyl, ** (See formula) ** wherein X1, in each case, is a member selected from the group consisting of hydrogen, halogen, lower alkyl and lower alkoxy and n is an integer having a value of 1 to 4; R1 is a member selected from the group consisting of hydrogen and lower alkyl; X is a member selected from the group consisting of hydrogen, halogen, lower alkyl, lower alkoxy and, taken together, two X radicals on adjacent carbon atoms of the benzene nucleus can be attached to form a hydrocarbylene chain of 3 to 4 atoms of carbon between its fixation points; and m, in each case, is an integer that has a value of 1 to 4; comprising the hydrolysis of a compound of the formula: ** (See formula) ** where R, R1, X and m are in accordance with that defined above, and Y is a hydrolyzable group selected from the group consisting of hydrocarbyloxycarbonyl, carbamoyl, N-substituted carbamoyl and cyano.
