摘要
少量低分子量醇的存在有助于丁炔二醇在Raney-Ni上第一步加氢生成丁烯二醇,但最终会降低丁二醇生成速度,其中甲醇的副作用最大。由于溶于水相的铜和铋在Ni上的沉积作用,会使丁二醇生成速度下降。金属Al^(+++)离子对Ni的毒化作用不明显。
The existence of trace low-molecular weight alcohols is conducive to the hydrogenation of butynediol to butenediol over a Raney-Nickel catalyst, but in the end it will reduce the formation rate of butanediol.Methanol has the most deleterious effect.The decrease in the formation rate of butanediol is attributed to the deposition of Cu and Bi in the reaction solutions on Ni.The poisonous influence of Al^(+++)ions on Ni is not significant.
