Title:
PROCESS FOR PRODUCING ALDEHYDE COMPOUND OR KETONE COMPOUND WITH USE OF MICROREACTOR
Document Type and Number:
WIPO Patent Application WO/2005/073155
Kind Code:
A1
Abstract:
A process for producing from a primary or secondary alcohol the corresponding aldehyde or ketone compound at relatively high temperature with a short period of time with high yield, which process comprises the step (1) of reacting a sulfoxide compound with its activator to thereby obtain an activated compound, the step (2) of reacting this activated compound with a primary or secondary alcohol to thereby obtain an alkoxysulfonium salt and the step (3) of reacting this reaction product with a base to thereby obtain an aldehyde or ketone, wherein at least one of these steps, preferably the steps (1) and (2) are carried out with the use of a microreactor.
