Abstract

Process for preparing aryloxyalkanoic acids, and especially a compound of formula ** (See formula) ** where R is selected from the group consisting of hydrogen, alkyl, aryl, aralkyl, cycloalkyl, cycloalkylalkyl and polyhalolevialkyl; R2 is taken from the group consisting of hydrogen and levyalkyl; X is selected from the group consisting of hydrogen, halogen, levyalkyl, levialkoxyl and trihalomethyl, and two of the X radicals of two contiguous carbon atoms form a hydrocarbon chain representing a member selected from the group consisting of trimethylene, tetramethylene and 1,3- butadienylene; and n is an integer less than 3; which comprises the reaction of a phenol of formula ** (See formula) ** with an acetic acid derivative of formula ** (See formula) ** where R, R2, X and n are as defined, and R1 is a member of the group consisting of hydrogen, hydrocarbyl, a metal cation and a quaternary ammonium cation, in the presence of a base; and, when R1 denotes hydrocarbyl, the hydrolysis of the resulting ester to obtain the respective carboxylic acid.
