Abstract:
1. A method for producing an aldehyde or ketone compound by using a microreactor, comprising (1) mixing a liquid containing a sulfoxide compound with a liquid containing an activating agent for the sulfoxide compound to cause a reaction with each other and produce an activation reaction product of the sulfoxide compound; (2) mixing a liquid containing the activation reaction product of the sulfoxide compound with a liquid containing at least one member selected from primary and secondary alkyl alcohols to cause a reaction with each other and prepare a liquid containing an alkoxysulfonium salt; and (3) mixing the resulting liquid containing an alkoxysulfonium salt with a basic compound-containing liquid to cause a reaction with each other and prepare a liquid containing an aldehyde or ketone compound corresponding to the alkyl alcohol, wherein at least one of (1), (2) and (3) is carried out by using a microreactor.
