Properties and stability

This product is toxic, can irritate the skin, can causesubacute dermatitis, and has a certain stimulating effect on the central nervous system. Production equipment should be sealed to prevent escape, leakage, dripping and leakage, and operators should wear��Protective equipment. See n-butylamine for other requirements.
　

Storage method

Storage: sealed and stored at room temperature.

Our country uses galvanized iron drums for sealed packaging, and Japan uses 200L steel drums, with a net weight of 160kg. During storage and transportation, the barrel mouth should be upward, stored in a cool and ventilated place, away from fire and heat sources.

Synthesis method

Brief description of the production method: Use lauric acid as raw material and react with ammonia gas in the presence of catalyst silica gel. The product is washed with water, dried and distilled under reduced pressure to obtain lauryl nitrile. Laurel nitrile is hydrogenated under the catalysis of active nickel, which is reduced to obtain dodecylamine. Add lauryl nitrile to the autoclave, add an appropriate amount of active nickel, and replace the indoor air with nitrogen. Heat to 80°C with stirring, repeatedly charge with hydrogen until no longer absorbed, and keep warm for 3 hours. Cool and distill the crude product under reduced pressure to obtain dodecaamine.

Purpose

Organic synthesis intermediate, used in the production of textile and rubber additives. It can also be used to prepare ore flotation agents, dodecyl quaternary ammonium salts, bactericides, insecticides, emulsifiers, detergents, and special disinfectants that prevent and treat skin burns, nourish body fluids, and provide antibacterial effects.
