A process for preparing saturated alcohols comprising effecting an aldol condensation of alkyl methyl ketones of 6 to 8 carbon atoms which are branched at the &bgr;-carbon atom with aldehydes of 4 to 15 carbon atoms which are branched at the &agr;-carbon atom to form &agr;,&bgr;-unsaturated ketones and subsequent hydrogenation of the &agr;,&bgr;-unsaturated ketones to obtain alcohols, wherein the aldol condensation is carried out at a temperature of 60 to 130° C. in the presence of a 30-55% strength aqueous solution of an alkali metal hydroxide resulting in very low by-product formation.
一种制备饱和醇的方法,包括将在β-碳原子处分支的6至8个碳原子的烷基甲基酮与在α-碳原子处分支的4至15个碳原子的醛进行醛缩反应,形成α,β-不饱和酮,然后对α,β-不饱和酮进行氢化反应以得到醇。其中,醛缩反应在存在30-55%强度的碱
金属氢氧化物
水溶液的条件下,温度为60至130°C进行,从而可以获得非常低的副产物形成。
