Patent number: 7538061Abstract: Disclosed is a new catalyst composition comprising a bimetallic Co—Fe catalyst, optionally complexed with a ligand selected from a N-heterocycle, phosphine, or porphorine ligand, that provides a lower cost alternative for the one step synthesis of 1,3-propanediol (1,3-PDO) from ethylene oxide and synthesis gas. For example, a catalyst containing cobalt carbonyl: iron carbonyl with no ligand, or a catalyst containing a cobalt carbonyl: octaethylporphine iron acetate provide moderate yields of 1,3-PDO in a one step synthesis under mild conditions.Type: GrantFiled: March 1, 2004Date of Patent: May 26, 2009Assignee: Shell Oil CompanyInventors: John Frederick Knifton, Talmadge Gail James, Lynn Henry Slaugh, Paul Richard Weider, Kevin Dale Allen, Joseph Broun Powell
