    摘要: 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.

    摘要: A subject of the present invention is a process for the reduction of a carbonyl compound. More precisely, the invention relates to a process for reduction of an aldehyde and/or of a ketone. The reduction process of the invention, which consists of reacting a carbonyl compound with an alcohol in the presence of a zeolite catalyst, is characterized by the fact that it comprises: mixing, in any manner whatever, the carbonyl compound and the alcohol, passing said mixture over a catalyst bed containing at least one zeolite, subjecting the reaction mixture leaving the catalyst bed to recirculation over the catalyst bed, for a number of times that is sufficient to obtain the desired degree of conversion of the substrate.
