摘要
Abstract
Aimed at 1arge amounts of by-product ketones generated in the industria1 preparation process, the secondary dodecano1 was synthesized by cata1ytic hydrogenation using n-dodecanone (n=2-6) as started ma-teria1 and ruthenium comp1ex as cata1yst. The effects of the amount of cata1yst, base, temperature, hydrogen pressure and reaction time on the hydrogenation were investigated.The optimum parameters are obtained at the mo1ar ratio of dodecanone and cata1yst of 50 000:1, the mo1ar ratio of KOtBu and dodecanone of 1:100, hy-drogen pressure of 3 MPa, reaction temperature of 80℃ and reaction time of 10 h. At this condition, the conversion rate of hydrogenation is up to 99.3%. The product was characterized by infrared spectroscopy. The cata1yst sti11 maintain its activation after 30 times recyc1ing, which demonstrated that the method is mi1d, en-vironmenta11y-friend1y and feasib1e to industria1 production .关键词
