Abstract
The invention pertains to a process for the preparation of an organic compound by a condensation reaction in which besides the organic compound other products are formed and one or more of the products formed during the preparation are extracted from the reaction mixture with the aid of a membrane. The reaction is carried out at a temperature above 80° C. and one or more of the products formed during the reaction are extracted from the reaction mixture by the aid of an inorganic membrane with an average pore size of the separating layer of less than 0.5 nm.
Claims12
A process for the preparation of an organic compound, wherein said compound is prepared by a condensation reaction carried out at a temperature above 70° C. and wherein in addition to said organic compound one or more other products are formed in the reaction mixture, said process comprising extracting said one or more of other products formed during said condensation reaction from the reaction mixture with the aid of an inorganic membrane containing a separating layer, wherein the average pore size of the separating layer of less than 0.5 nm.
A method for improving the reaction rate of condensation reactions carried out at temperatures above 70° C., wherein said reaction forms, as by-products, a member from the group consisting essentially or water, ethanol, methanol, NH3 and mixtures thereof, said method comprising removing one or more of said by-products from the reaction mixture with the aid of an inorganic membrane containing a separating layer, wherein the average pore size of the separating layer of less than 0.5 nm, thereby driving said condensation reaction towards formation of the desired product.
