Abstract
Process for the production of organic compounds in a membrane reactor. Inorganic membranes composed of an inorganic backing layer and an inorganic interlayer are used in the membrane reactor. The inorganic interlayer may be modified with organic groups.
Claims17
In a process for the catalytic production of an organic compound in which reactants are added to a reaction vessel, a reaction is catalyzed by means of a homogeneously or colloidally soluble catalyst, and product is removed, the improvement comprising:
- (a) retaining said catalyst in said reaction vessel during product removal by means of a membrane, wherein said membrane comprises a backing layer of inorganic silicon or metal oxides and an interlayer of inorganic silicon or metal oxides;
- and
- (b) removing said product by allowing the liquid in said reaction vessel to crossflow said membrane.
