Abstract:
1. A method for preparing at least one chemical reaction product by means of chemical reaction of one or more reactants, optionally dissolved in one or more solvents, which are supplied as a feed flow, through the contact with a heterogeneous catalyst in a continuously operated fixed-bed reactor packed with a particle bed, a continuous annular chromatograph (CAC), packed with said particle bed, being used as said fixed-bed reactor in which said at least one reaction product is formed and purified and said at least one purified reaction product as well as any by-products and/or unreacted reactants present are withdrawn from said annular chromatograph each at a different and predetermined rotational angle position, using only one type of particulate material in a single particle bed as both catalyst for the formation of said at least one reaction product in said particle bed and as chromatographic medium for the purification thereof, and recirculating and reusing any unreacted reactants and/or by-products in the chemical reaction.
