Latest Patents

Douglas Nugent holds a patent for the "Direct synthesis of cyclic carbonates using choline chloride as catalyst under mild conditions." This method involves the reaction of at least one epoxide with carbon dioxide in the presence of a choline catalyst, such as choline chloride. The process operates under mild conditions, with temperatures ranging from about 25° C. to 150° C. and pressures from atmospheric to 75 psi (0.52 MPa). Notably, the choline catalyst can be used alone without the need for a co-catalyst or hydrogen bond donor. The concentration of the choline catalyst in the solvent varies from about 0.5 mol % to about 10 mol %, based on the epoxide.
