标题 :One-step production of 1,3-propanediol from ethylene oxide and syngas with a cobalt-iron catalyst

摘要: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.

摘要:Disclosed is a new catalyst composition comprising a bimetallic Co—Ru catalyst complexed with a N-heterocylcic ligand that is effective, economical, and provides improvements in oxidative stability in the one step synthesis of 1,3-propanediol (1,3-PDO) from ethylene oxide and synthesis gas. For example, cobalt-ruthenium-2,2′-bipyrimidine, 2,2′-dipyridyl, or 2,4,6-tripridyl-s-triazine catalyst precursors in cyclic ether solvents, such as 1,3-dioxolane, 1,4-dioxolane, 1,4-dioxane, and 2-ethyl-2-methyl-1,3-dioxolane, provide good yields of 1,3-PDO in a one step synthesis.

标题 :Synthesis of aliphatic 1,3-diols utilizing reduced ligand concentration and water extraction
发明人：POWELL JOSEPH BROUN; WEIDER PAUL RICHARD; KNIFTON JOHN FREDERICK; ALLEN KEVIN DALE; SLAUGH LYNN HENRY; ARHANCET JUAN PEDRO
权利人:SHELL OIL CO
摘要:This invention is a process for synthesizing aliphatic 1,3-diols in one step by hydroformylation and hydrogenation of oxirane, carbon monoxide, and hydrogen employing a catalyst comprising a cobalt carbonyl compound and a cocatalyst metal compound ligated with a ligand in a ligand to cocatalyst metal atom molar ratio in the range of 0.2:1.0 to 0.6:1.0, optionally in the presence of a promoter, where recovery of product is preferably accomplished via water extraction of a diol rich phase from the bulk reaction mixture. The process modifications can, particularly in combination, be beneficial with respect to product recovery, catalyst recycle, and overall economics of a one-step process for producing aliphatic 1,3-diols.

标题 :Process for preparing alcohols from olefins and synthesis gas
发明人：KNIFTON JOHN F; GRIGSBY JR ROBERT A
权利人:TEXACO INC
摘要:This invention concerns an improved process of preparing predominantly linear alcohols which comprises the steps of contacting a mixture of terminal and/or internal olefins and synthesis gas with a catalyst system comprising a ruthenium-containing compound in conjunction with one or more tertiary amine promoters, dispersed in a low melting quaternary phosphonium salt and heating said resultant reaction mixture under a pressure of 100 psi or greater at a temperature of at least 50 DEG C. for a sufficient time to produce said alcohols.
