Diethylamine

　　Main Uses

　　Organic Synthesis Intermediates:

　　Pharmaceutical field: Used in the synthesis of local anesthetics (e.g., procaine), antimalarials, antihistamines, etc.;

　　Agrochemical field: Preparation of insecticides (e.g., imidacloprid intermediates), herbicides, fungicides;

　　Dyes and auxiliaries: Synthesis of dye intermediates, rubber accelerators (e.g., diethyldithiocarbamates), surfactants (e.g., cationic softeners).

　　Gas Purifying Agent: Utilizes strong alkalinity to be absorb acidic components in industrial gases (e.g., H₂S, CO₂); efficiency is higher than monoethylamine, commonly used in desulfurization processes for oil refineries and natural gas treatment.

　　Catalysts and Additives:

　　As a catalyst for polymerization reactions (e.g., used in polyurethane foams, epoxy resin curing);

　　As a brightening agent in the electroplating industry to improve coating uniformity;

　　As a raw material for vulcanization accelerators in the rubber industry.

　　Solvent and Extractant: Used as a solvent for certain organic reactions, or as an extractant to separate rare metals (e.g., extracting specific ions from rare earth elements)
