摘 要:對環(huán)氧乙烷羰基合成1,3 丙二醇的催化體系進(jìn)行了初步研究。針對一步法和二步法的技術(shù)路線(xiàn),考察了不同催化條件對反應結果的影響,如主催化劑、膦配體、促進(jìn)劑、活化劑和溶劑等。結果表明:Co/PR3催化劑體系適用于合成反應,適宜的促進(jìn)劑有利于環(huán)氧乙烷羰基化制1,3 丙二醇,一步法優(yōu)于二步法。
關(guān)鍵詞:環(huán)氧乙烷; 羰基合成; 1; 3-丙二醇

Abstract:The hydroformylation of 1,3-propanediol from ethylene oxide was summarized by one-step and two-step. The catalyst conditions of 1,3-propanediol were researched, such as main catalyst, accelerant, solvent, etal. It was found that the effect of the various compositions of catalyst with CO/PR3 was held true, and agreeable accelerant was of great advantage to synthesize. The yield of 1,3-propanediol by One-step was better than that by two-step.
Key words:Ethylene oxide; Hydroformylation; 1; 3-Propanediol
