Fatty amine–is an important product of oil and grease chemical industry.

Fatty amine, refers to a large class of organic amine compounds with carbon chain length within the range of C8-C22, it is divided into four major categories of primary amine, secondary amine and tertiary amine and polyamine like general amines, while primary, secondary and tertiary amines depend on the number of hydrogen atoms in the ammonia that are replaced by alkyl groups.

Fatty amines are one of the main intermediates of the three major lipid chemistries (fatty alcohols, fatty acids and fatty amines). At present, most of the industrial production of fatty amines is based on the reaction of natural fatty acids with ammonia to generate fatty nitrile, and then fatty nitrile as raw material to generate fatty amines under the action of catalysts.

Application of fatty amine and its derivatives

Bactericide and algaecide

Some tertiary amines can be used as bactericides after quaternization, and most of the quaternary ammonium salts used as bactericides contain benzyl group in their structure. Quaternary ammonium salts are used for sterilization purposes in the following areas: domestic, medical and industrial sterilization, disinfection, cleaning, mildew; swimming pool algae, etc.; disinfection in the laundry process; oil field microbicides and so on.

Anti-caking agent  

Tertiary amines and their salts can be used as effective anti-caking agents for fertilizers or explosives. Fatty amines used as anti-caking agents for explosives require a higher freezing point.

Pigment and ink dispersant  

Tertiary amines are used as pigment dispersants. Adding tertiary amines reduces the grinding time for pigment production, thus increasing the yield. Fatty diamines and polyamines are important dispersants for inks and pigments.

Corrosion and preservative

Alkyl propylene diamines are commonly used as corrosion inhibitors. They play an important role in oilfield regeneration process.

Emulsifiers  

Tertiary amine can be used to produce quaternary ammonium salt-type asphalt emulsifiers, such emulsifiers are widely used in the paving and maintenance of high-grade highways, which can reduce the amount of labor for construction and maintenance, and help to improve the service life of the road surface.

Daily chemical industry applications  

The amine oxide prepared by tertiary amine is mainly used for the preparation of daily cleaning products. Such as conditioning shampoos, baths, facial cleansers, foam preparations, light dirtiness silk wool detergent. Used in cosmetics as moisturizer, emulsifier, thickener and bactericidal preservative.
