ABSTRACT:
A method is provided for the preparation of 2-acetyl-.gamma.-butyrolactone by condensing .gamma.-butyrolactone with an acetic acid ester in the presence of a strongly basic condensation agent, followed by protonation of the initially formed enolate, wherein the .gamma.-butyrolactone, the acetic acid ester and the condensation agent are fed continuously into the reaction zone in a ratio of from 1.0 to 6.0 parts by mols of acetic acid ester and from 0.9 to 1.6 parts by mols of the strongly basic substance per part by mols of .gamma.-butyrolactone, and wherein the reaction mixture formed by condensation is withdrawn from the reaction zone, either batchwise or continuously, and protonated.
