Dimethyl oxalate 553-90-2

Main Uses: As an important chemical and pharmaceutical raw material, dimethyl oxalate is often used to prepare various organic solvents, extractants, adhesives, plasticizers, and various pharmaceutical intermediates, such as for the synthesis of Vitamin B13, hydrogenation to prepare methyl glycolate and ethylene glycol, and replacing diethyl oxalate to synthesize sulfamethoxazole, etc.;

Using dimethyl oxalate as a raw material to produce methyl ethyl oxalate and diethyl oxalate; using dimethyl oxalate to replace diethyl oxalate as the starting material, without changing the rest of the production process and raw materials, through multiple steps such as Claisen condensation, acidification, cyclization, and ammonolysis to produce 5-methyl-3-formylisoxazole, and testing and analyzing the obtained product, it was found that there was no difference in product quality; meanwhile, because the price of dimethyl oxalate is lower than that of diethyl oxalate, the production cost of the product is reduced, improving its competitiveness in the market;

Dimethyl oxalate can also react with ammonia to generate oxamide, which can be used as a stabilizer for nitrocellulose products, and as a gas generating agent and cooling agent in gas generators; meanwhile, oxamide can also be used as a slow-release nitrogen fertilizer, etc.
