Title:
METHOD FOR PRODUCING ACETAL COMPOUND
Document Type and Number:
WIPO Patent Application WO/2017/204155
Kind Code:
A1
Abstract:
A method for producing an acetal compound, the method comprising: a step (A) for oxidizing a compound represented by general formula (1) (R1 represents an alkyl group having 1-6 carbon atoms) to obtain a compound represented by general formula (2) (R1 is as defined above); and a step (B) for acetalizing the compound represented by general formula(2) obtained in step (A), in the presence of an acid, to obtain a compound represented by general formula (3) (R1 is as defined above, R2 and R3 each independently represent an alkyl group having 1-6 carbon atoms, or are linked together to represent an alkylene group having 2-6 carbon atoms).
