摘要

Process for the preparation of the acid (odor-4-phenoxy) -2-methyl-2-propionic acid and its esters of the general formula ** (see formula) ** Wherein r means hydrogen or a lower alkyl radical, characterized in that a composition composed of p-chlorophenol, acetone and a methylhalogenated derivative is essentially subjected to reaction, under reflux and in a strong alkaline medium, in the presence of an excess of ketone with solvent character, and, once separated by acidification of the reaction mass, the acid product of the above-mentioned general formula is optionally subjected to esterification with the corresponding lower alcohol, in the presence of a catalyst.
