Method of retaining the quality of 2-methyl-3-(3,4-methylenedioxyphenyl) propanal and process for producing the same
The present invention relates to [1] a method for keeping a quality of 2-methyl-3-(3,4-methylenedioxyphenyl)propanal useful as a perfume, which comprises incorporating from 50 to 3000 ppm of 1-acetyl-3,4-methylenedioxybenzene in the 2-methyl-3-(3,4-methylenedioxyphenyl)propanal; [2] a process for producing 2-methyl-3-(3,4-methylenedioxyphenyl)propanal having a content range from 50 to 3000 ppm of 1-acetyl-3,4-methylenedioxybenzene; and [3] 2-methyl-3-(3,4-methylenedioxyphenyl)propanal having a content range from 50 to 3000 ppm of 1-acetyl-3,4-methylenedioxybenzene.
1. A method for keeping a quality of 2-methyl-3-(3,4-methylenedioxyphenyl)propanal, comprising:
incorporating from 50 to 3000 ppm of 1-acetyl-3,4-methylenedioxybenzene in the 2-methyl-3-(3,4-methylenedioxyphenyl)propanal.
2. The method for keeping a quality of 2-methyl-3-(3,4-methylenedioxyphenyl)propanal according to claim 1 , wherein the 2-methyl-3-(3,4-methylenedioxyphenyl)propanal is produced from 1-acetoxy-2-methyl-3-(3,4-methylenedioxyphenyl)-1-propene.
