Fatty amine refers to a large group of organic amine compounds with carbon chain length in the range of C8-C22. Like general amines, it is divided into four categories: primary amine, secondary amine, tertiary amine and polyamine. Tertiary amines depend on the number of hydrogen atoms in ammonia replaced by alkyl groups.
Primary amines can be used as corrosion inhibitors, lubricants, mold release agents, oil additives, pigment processing additives, thickeners, wetting agents, fertilizer anti-dust agents, engine oil additives, fertilizer anti-caking agents, mold forming agents, floatation agent, gear lubricant, hydrophobic agent, waterproof additive, wax emulsion, etc. Saturated high-carbon primary amines such as stearylamine are used as release agents for hard rubber and polyurethane foam. Dodecylamine is used in the regeneration of natural and synthetic rubber and as a surfactant in electroless tin plating baths, as well as malt derivatives produced by reductive amination of isomaltose, and oleylamine is used as a diesel fuel additive.
Fatty amines and their salts can be used as effective ore flotation agents, chemical fertilizers or explosives anti-caking agents, paper waterproofing agents, corrosion inhibitors, lubricating additives, bactericides in the petroleum industry, fuel and gasoline additives, electronic cleaning agents, emulsifying agents, production of organometallic clays, pigment processing additives, water treatment agents, molding agents, etc. Primary amines can be used to produce quaternary ammonium salt type asphalt emulsifying agent, which are widely used in the paving and maintenance of high-grade highways, which can reduce the labor of construction and maintenance and help increase the service life of the road surface.
The adduct of fatty amine and ethylene oxide is mainly used as an antistatic agent in the plastic industry. The ethoxylated fatty amine cannot be dissolved in the plastic, so that it migrates to part of the surface of the plastic. Once it reaches the surface, it is ethoxylated. The amine will fully absorb the moisture in the atmosphere, and the surface of the plastic will become an antistatic plastic.
Dodecylamine reacts with methyl acrylate to obtain N-dodecyl-B-alanine after saponification and neutralization. The properties of this type of surfactant are: the aqueous solution is a light-colored or colorless transparent liquid, easily soluble in water or ethanol, which is easily biodegradable, resistant to hard water, has little irritation to the skin, and is less toxic. Uses: foaming agent, emulsifying agent, corrosion inhibitor, liquid detergent, shampoo, hair conditioner, softener, antistatic agent, etc.
