ACETYLENE ALDEHYDE, ITS MANUFACTURING METHOD, ACETYLENE ALDEHYDE ACETAL AND ITS MANUFACTURING METHOD

摘要

PPROBLEM TO BE SOLVED: To provide an acetylene aldehyde which has high productivity and a small environmental load and is low-cost, and its manufacturing method. PSOLUTION: The acetylene aldehyde is represented by formula (1): RSP1/SPRSP2/SPRSP3/SPSi-C≡C-CHO (wherein RSP1/SP, RSP2/SPand RSP3/SPare each an alkyl group or a phenyl group, excepting that one of RSP1/SPto RSP3/SPis a methyl group and the remaining are phenyl groups). The method for manufacturing the acetylene aldehyde comprises subjecting an acetylene alcohol represented by formula (2): RSP1/SPRSP2/SPRSP3/SPSi-C≡C-CHSB2/SBOH (wherein RSP1/SP, RSP2/SPand RSP3/SPare each an alkyl group or a phenyl group, excepting that one of RSP1/SPto RSP3/SPis a methyl group and the remaining are phenyl groups) to electrolytic oxidation in the presence of an oxidizing agent.
