The invention relates to a production process of isobutyric acid, comprising the following steps: S1. adding isobutyraldehyde into an oxidation reaction tower through a reaction pump, adding a catalyst to carry out an oxidation reaction, and feeding air during the reaction to obtain isobutyric acid Crude product; S2. The isobutyric acid crude product is added into the rectification tower through the rectification pump to carry out rectification to obtain the product. The isobutyraldehyde is oxidized to synthesize isobutyric acid by using CuO - Cr2O3 - CoO/zeolite and V2O5 /CNTs synergistically as a catalyst, and rectifying to synthesize isobutyric acid, and has the advantages of high conversion rate, high selectivity It has good performance, high yield, less pollution, catalyst can be reused, and has good economic and environmental benefits. |
