呋喃衍生物糠酸阳离子交换树脂和糠醛树脂载上 Cu~(++)或 Ni~(++)后,与 KBH_4及 H_2O 组成非均相加氢催化体系,进行了乙腈及乙炔的加氢催化研究.结果表明: 所用催化剂具有较好的催化活性,其对乙腈的加氢催化性能更好些.其中.NO.3Cu 树脂催化的乙腈加氢反应,25分钟时乙烷和乙烯的总生成率为0.015%—0.057%,平均转化数则是4.04×10~(-3)—5.68×10~(-3)微摩[产物]/微摩 Cu·分,生成乙烷的选择性为79.4%-87.2%.因打开C≡N 键比 C≡C 键更困难,且 C≡N 更接近于 N≡N,也由于呋喃衍生物糠酸阳离子交换树脂体系和固氮酶体系的结构不同、以及前者较易制备,故对于固氮反应的研究而言,本文结果是具有一定的积极意义的.
Furan derivative furoic acid cation exchange resin and furfural resin supported on Cu ~ (++) or Ni ~ (++), and heterogeneous hydrogenation catalyzed by KBH_4 and H_2O, catalytic hydrogenation of acetonitrile and acetylene The results show that the catalyst has good catalytic activity and better catalytic performance for the hydrogenation of acetonitrile, in which the NO3Cu resin catalyzed the hydrogenation of acetonitrile, the total formation rate of ethane and ethylene at 25 minutes is 0.015% -0.057%, the average conversion is 4.04 × 10 -3 -5.68 × 10 -3 micromol [product] / micromol Cu · min, selectivity to ethane is 79.4% 87.2% .The opening of C≡N bond is more difficult than that of C≡C bond, and C≡N is closer to N≡N. Due to the different structure of furan derivative furfural cation exchange resin system and nitrogenase system, Easy to prepare, so for the study of nitrogen fixation, the results of this paper is of some positive significance.
