鉄を主体とする混合金属酸化物触媒による高級アルコールの製造研究

抄録

The anthers previously reported that Fe-Cu-O catalyst had high activity to catalytic hydrogenolysis of higher fatty ester to higher alcohol. After that, it was found that Fe-Cu-AI-O catalyst had higher activity when proper amount of Al was contained as third component.
Hydrogenolysis of methyl ricinoleate to 1, 12-octadecanediol was studied using the catalyst. The yield was 77%. But when triglyceride was used as raw material, the yield was 50%.
Preparation of unsaturated higher alcohol using Fe-Cu-Cd-O, which was prepared newly, was studied, but 65% of unsaturation on the product vanished when 93% of the ester was hydrogenolzyed.
From the study of X-ray defraction on these catalysts before and after the reduction, it was recognized that, as to Fe, Fe₃0₄ was of active from in the reduction.
