PROCESS FOR THE PREPARATION OF 1-(2,6,6-TRIMETHYL-2-CYCLOHEXENE-1-YL)-BUT-2-ENE-1-ONE

摘要

The present invention relates to a novel process for the preparation of 1-(2,6,6-trimethyl-2-cyclohexene-1-yl)-2-but-2-ene-1-one commonly known as a-Damascone, by acylation of unsaturated cyclic hydrocarbon 2,6,6-trimethyl-1-cyclohexene followed by work up and its purification by vacuum distillation.
