Description

Obtaining

Triethanolamine (nitrilotriethanol) manufactured by ethoxylation of ammonia.

Application

Triethanolamine is used for gas cleaning in obtaining pure carbon dioxide, in the textile and cement industry, in the manufacture of cosmetic products as raw material in a number of organic syntheses. Depending on the fractional composition triethanol is produced in grades A, B and C.

Safety requirements

Triethanolamine — fire hazard, the degree of impact on the body is a substance third risk class.

Packing

Triethanolamine is poured into clean dry steel drums; imported barrels meeting the strength characteristics of the national standards for similar containers; second hand drums meeting relevant regulatory requirements; rail and road tankers.

Guaranteed shelf life

3 years from date of manufacture.

Safety requirements

Class of danger	3
Basic properties and hazards
Basic properties	Oily, viscous, hygroscopic, flammable liquid from yellow to dark brown with a specific amine odor. Infinitely miscible with water, soluble in ethanol, benzene, chloroform, and poorly in heptane. It has alkaline properties. The boiling point is 220 °C. Vapors are heavier than air and accumulate in low areas of the surface, basements, tunnels. Pollutes water.
Explosion and fire	Flammable. Fire hazard. A flash point of 232 °C, at the temperature 395 °C self-ignition can occur. Ignited by an open flame. Dust and fumes can form explosive mixtures with air when heated. Containers may explode when heated. Burning producing toxic gases (cyanide, nitrogen oxides).
The risk to humans	Owing to the low volatility, low vapor pressure and low toxicity in the working environment there is low danger. It is an irritant to skin and mucous membranes of the upper respiratory tract and eyes. Cumulative properties are expressed moderately. It is harmful if inhaled, swallowed (nausea, headache, cough, drooling, eye pain, feeling of choking) Skin (tingling, itching), Eye (red). It penetrates intact skin leading to chemical burns.
