참여 물질

반응 단계

The production process (A) comprises the steps of (1) reacting 1,2-methylenedioxybenzene and 2-methyl-3,3-diacetoxypropene with each other to produce 1-acetoxy-2-methyl-3-(3,4-methylenedioxyphenyl)-1-propene; and (2) subjecting the obtained 1-acetoxy-2-methyl-3-(3,4-methylenedioxyphenyl)-1-propene to hydrolysis reaction or to transesterification reaction with an alcohol, followed by subjecting the resulting reaction mixture to distillative purification, to thereby adjust a content of 1-acetyl-3,4-methylenedioxybenzene as a by-product in the 2-methyl-3-(3,4-methylenedioxyphenyl)propanal to from 50 to 3000 ppm.
