Diethylamine Use and Manufacturing

Methods of Manufacturing

The preparation method is to use a mixture of ethanol, ammonia and hydrogen, preheated to a temperature of about 180°C, under the action of a nickel-copper catalyst, enter the first converter (temperature about 200°C) and the second converter ( The temperature is about 80°C) for the synthesis reaction, and the reaction product is crudely distilled and rectified to obtain the finished product.

Uses

Verification of antimony, platinum and tin, determination of carbon disulfide and magnesium, organic synthesis. Diethylamine is a solvent and an intermediate of chemical raw materials. It can be used to produce drugs such as procaine, chloroquine, nicosha, cluramin, and sulfonamide. It can also be used to produce pesticides, dyes, rubber vulcanization accelerators, and mineral processing. Medicament (sulfur and nitrogen No. 9); textile auxiliary, bactericide, corrosion inhibitor, polymerization inhibitor and antifreeze, etc.
