brief introduction | 3, 5-dimethylbenzoic acid is widely used in polymer production. the main production method is oxidation of metal salt catalysis. the traditional production process requires adding materials to the reactor or the reaction tower in proportion and filling with preheated air at a certain pressure. After the reaction is completed, the reaction kettle releases the pressure, releases the material, cools and crystallizes, and filters to obtain the filter cake as the product. |
use | 3, 5-dimethylbenzoic acid is an intermediate of mebohydrazide and mebohydrazide insecticides. Used for organic synthesis, pesticide and pharmaceutical intermediates Organic synthesis intermediates. |
production method | its preparation method is to add 1,3, 5-trimethylbenzene and catalyst nickel salt into the oxidation reactor, heat to a certain temperature, and pass air to oxidize to produce products. |
