Title:
METHOD FOR PRODUCING 1, 2-BENZENE DIMETHANOL COMPOUND
Document Type and Number:
WIPO Patent Application WO/2017/138068
Kind Code:
A1
Abstract:
The present invention relates to: a method for producing a compound represented by formula (1), which comprises a step for hydrolyzing a compound represented by formula (2) under acidic or basic conditions, a step for reacting a compound represented by formula (3) and a metal acetate salt with each other, and a step for halogenating a compound represented by formula (4); a method for producing a compound represented by formula (1), which comprises a step for reacting a compound represented by formula (3) and a metal acetate salt with each other and then causing a further reaction by adding an alcohol, water and a base into the resulting reaction liquid; a method for producing a compound represented by formula (1), which comprises a step for causing a reaction of a compound represented by formula (3) in the presence or absence of a base, an ionic liquid and a metal sulfate salt in water or in a mixed solvent of water and an organic solvent; a compound represented by formula (2) or a salt thereof; and a compound represented by formula (3) or a salt thereof.
