アセチレンとその誘導體に關する硏究(第8報) : 氣相法によるアセチレンよりアセタルデハイドの合成に關する硏究(その1)

Abstract

The best catalyst for this subject was found to be cadmium chromateacid clay, after being studied on 20 kinds of catalysts. Using this catalyst, under the following conditions: reaction temperature 250°-350°; space velocity of acetylene, about 200 1; mol ratio of acetylene for water, 1:1.5, we obtained the following results: reaction ratio of acetylene, 20-30%; theoretical yield of acetaldehyde, about 85%; durability of the catalyst, considerably long when reactivated occasionally with air and steam; exodus gas, contained CO2, CO, CH4 and H2, which were found to have no bad effect in the repeated use.
