Title:
N-ヘテロ環配位子を有する触媒を用いた酸化エチレンと合成ガスからの1,3-プロパンジオールの一段での製造
Document Type and Number:
Japanese Patent JP2004526568
Kind Code:
A
Abstract:
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.
