Uses of Amine-Type Derivatives

USES OF AMINE-TYPE DERIVATIVES A. Aliphatic Amines 

The aliphatic amines are valuable intermediates for chemical synthesis applications, Reaction of ethylamine with cyanuric chloride yields triazine-type herbicides, Diethylamine is used in the preparation of vulcanization accelerators where reaction with carbon disulfide yields a dithiocarbamate. Triethyl-amine is used as an acid acceptor in chemical syntheses and as a salt former in various purification processes. The amine is used as a corrosion inhibitor in aqueous systems, as a catalyst in polyurethane applications, in textile and photographic applications, and in anodic electrocoating. 

The two most important propylamines are isopropylamine and dipropylamine. The former is a valuable intermediate in the preparation of agricultural chemicals, while the latter is the starting material for herbicides. The demand for these two propylamines equals the total demand for the ethylamines. 

Butylamines are intermediates in the preparation of emulsifying agents, desizing agents for textiles, corrosion inhibitors, rubber chemicals, agricultural chemicals, and pharmaceuticals. Tributylamine is used as a polymerization catalyst and as an acid acceptor. Cyclohexylamine is used primarily as a salt-forming component in certain applications and as an intermediate in the synthesis of certain amides. It is also used as a solvent and corrosion inhibitor for aqueous systems. 

The alkanolamines contain dual functional groups and thus undergo reactions common to both amines and alcohols. The primary, secondary, and tertiary alkanolamines display the typical reactivity of primary, secondary, and tertiary amines. The alcohol functional group exhibits reactions typical of primary and secondary alcohols. The dual functionally of the alkanolamines permits certain reactivity not available in either an alcoholic or amine solvent.
