Use

Diethylamine is manufactured by heating ethyl chloride and alcoholic ammonia under pressure or by hydrogenation of aziridines in the presence of catalysts. DEA is used as a solvent, as a rubber accelerator, in the organic synthesis of resins, dyes, pesticides, and pharmaceuticals, in electroplating, and as a polymerization inhibitor. Other applications include uses as a corrosion inhibitor. It was reported noneffective as a skin depigmentator.
