Triethanolamine is an ammonia odor colorless to pale yellow viscous liquid, soluble in water, ethanol, alkaline, aqueous solution PH value of about 10.5, is a widely used chemical raw materials, as a non-reinforcing carbon black rubber vulcanization active agents, oils and waxes emulsifiers, metal cutting coolant, rust inhibitors, cement early strength agent, a neutralizing agent, an acid gas absorbent, cosmetic wetting agents. Chinese name: triethanolamine TEOA; English name: Triethanolamine abbreviation: TEOA, TEA, Alias: 2,2, 2 ,, hydroxy triethylamine, triethanolamine; formula: C6H15O3N Molecular Weight: 149.19 Structural Formula: N ( CH2CH2OH) 3 CAS No. 102-71-6 formula: N (CH2CH2OH) 3 monoethanolamine content: 0% diethanolamine content: 0.09% Color: 17 moisture content: 0.017% Security: Common Goods Storage: cool and well-ventilated place Product Grade: Industrial Grade Appearance: Liquid Physical State: Liquid implementation of quality standards: GB Physical and Chemical Properties colorless to pale yellow viscous liquid, slight ammonia odor, soluble in water, ethanol. Alkaline aqueous solution PH value of about 10.5. Can corrode copper, aluminum and its alloys. Liquid and vapor corrosive to the skin and eyes. Can form an ester, amide salts of the acid reaction. Melting point 18 ~ 21 ℃, cools to form a supercooled liquid. The relative density of about 1.12, the boiling point of 190 ~ 193 ℃ (5 * 133Pa), atmospheric pressure to about 335 ℃ decomposition. The vapor pressure of about 1.3Pa. Flash point of 185 ℃, auto-ignition temperature 315 ℃. TEA products on the market more than 99% of the high purity products, as well as TEA content of 95%, 90%, 85% and other grades of products, generally aqueous, diethanolamine and the like. First grade purity ≥98.5%, moisture ≤0.3%. Characteristics and uses triethanolamine is a widely used chemical raw materials, for non-black reinforced rubber vulcanization active agents, oils and waxes emulsifiers, metal cutting coolant, rust inhibitors, cement early strength agent , neutralizers, acid gas absorbent, cosmetic wetting agents. Polyether polyurethane can be used in the field of initiator, a crosslinking agent and a co-catalyst polyurethane foam and elastomer. Since the tertiary N group, with some catalyst, and can neutralize the acidic components, to protect the main catalyst tertiary amine compound of the polyurethane foam composition. General for the preparation of surfactants, cutting oil, antifreeze, in the metal processing industry, used to prepare corrosion inhibitors to protect the metal surface to prevent oxidation; in the electroplating industry, can replace sodium cyanide HUA, or the use of micro cyanide electroplating, called micro-toxic cyanide or non-cyanide plating, plating internal quality fully comparable with cyanide plating; the main raw material of cement grinding aids (accounting for about 75% of the total formulation aids), added help grinding agents may increase cement production by 10% -20%; directly into the cement clinker grinding aid (a ratio of about one ten thousandth), mixed after milling, not only to increase cement production, and increase the fineness of improving the quality of the label, to reduce energy consumption ; concrete superplasticizer raw materials; concrete early strength materials. Other uses detergent raw materials; cosmetics raw materials; skin care products, cosmetics raw materials. Triethanolamine is efficient chelating agent can chelate heavy metals.
