光照下,以甲醇为氢源,以NiCl2、Ni(OAc)2或CoCl2为催化剂,1-辛烯可以发生催化转移加氢反应,得到辛烷,主要副产物为双键异构的2-辛烯和3-辛烯。综合催化剂的加氢活性和产物辛烷的选择性,NiCl2的催化效果最好,且NiCl2的催化活性在293~333K范围内随温度升高而增加。以NiCl2为催化剂,在反应体系中添加三正丁胺,于293K下反应24h,辛烷的产率由45%提高到65%,选择性由57%提高到70%。
Under light irradiation, 1-octene can be catalytically transferred and hydrogenated by using methanol as hydrogen source, NiCl2, Ni (OAc) 2 or CoCl2 as catalyst to obtain octane. The main by-product is 2- Ene and 3-octene. The catalytic activity of NiCl2 was the best, and the catalytic activity of NiCl2 increased with the increase of temperature in the range of 293 ~ 333K, based on the hydrogenation activity of the catalyst and the selectivity of the product octane. With NiCl2 as catalyst, tri-n-butylamine was added to the reaction system and reacted at 293K for 24 hours. The yield of octane increased from 45% to 65% and the selectivity increased from 57% to 70%.
