titleOfInvention | The production process of isobutyric acid |
abstract | 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, and adding a catalyst for oxidation reaction, and feeding air during the reaction process to obtain isobutyric acid Crude product; S2. Put the crude product of isobutyric acid into a rectification tower through a rectification pump for rectification to obtain the product. The isobutyraldehyde oxidative synthesis of isobutyric acid of the present invention, by using CuO-Cr 2 O 3 -CoO/zeolite and V 2 O 5 /CNTs synergistically as a catalyst, and synthesizing isobutyric acid through rectification, has high conversion rate and selectivity Good performance, high yield, less pollution, reusable catalyst, good economic and environmental benefits. |
