METHOD OF RETAINING THE QUALITY OF 2-METHYL-3-(3,4-METHYLENEDIOXYPHENYL)PROPANAL AND PROCESS FOR PRODUCING THE SAME

摘要

There are provided [1] method of retaining the quality of 2-methyl-3-(3,4-methylenedioxyphenyl)propanal containing 50 to 3000 ppm of 1-acetyl-3,4-methylenedioxybenzene which is useful as a perfume; [2] process for producing the 2-methyl-3-(3,4-methylenedioxyphenyl)propanal containing 50 to 3000 ppm of 1-acetyl-3,4-methylenedioxybenzene; and [3] 2-methyl-3-(3,4-methylenedioxyphenyl)propanal containing 50 to 3000 ppm of 1-acetyl-3,4-methylenedioxybenzene.
