Abstract:
The invention relates to a method for producing optionally substituted methylenedioxybenzene. The invention particularly relates to the production of methylenedioxybenzene. The inventive production method is characterized by the fact that it involves the reaction of an optionally substituted catechol with an aldehyde in the presence of a solid acid catalyst selected among: a titanium silicalite and a zeolite that is doped with tin and/or titanium.
