Abstract
A novel catalyst system useful in preparation of dimethyl carbonate is prepared by complexing a metal salt such as cupric chloride CuCl.sub.2 with a ligand formed by reacting a carbonyl-containing organic compound such as ethyl formate with an organosilicon compound containing alkoxy and amine fucntionality, such as 3-aminopropyltriethoxysilane.
Claims1
The process which comprises reacting in liquid phase at 0.degree. C.-150.degree. C.
- (i) one mole of 3-aminopropyl triethoxy silane with
- (ii) 0.1-10 moles of ethyl formate thereby forming product
- (EtO).sub.3 Si (CH.sub.2).sub.3 NHCHO
- reacting said product with silica or alumina thereby forming functionalized silica or alumina;
- and
- recovering said functionalized silica or alumina.
