詳細

アプリケーション

m-Cresol can be used as a starting material to synthesize:

• Thymol via isopropylation reaction with 2-propanol in the presence of an acid catalyst.
• Terpolymeric resin by an acid-catalyzed polycondensation reaction with hexamine and formaldehyde.
• 4,7-Dimethylcoumarin via modified Pechmann condensation reaction with ethyl acetoacetate.
