나이트릴로트라이아세트산 C화학적 특성, 용도, 생산
화학적 성질
Nitrilotriacetic acid, also known as NTA, is a white crystalline powder. It can dissolve in ammonia and alkali solutions while being slightly soluble in hot water. However, it is insoluble in water and most organic solvents. NTA can form mono-, di-, and tribasic salts, all of which are soluble in water. Combustible. 70% biodegradable.제조 방법
The synthesis of nitrilotriacetic acid involves the following steps:Chloroacetic acid is reacted with sodium hydroxide to produce sodium chloroacetate.
Sodium chloroacetate then reacts with ammonium chloride to form sodium aminotriacetate.
The resulting sodium aminotriacetate is acidified to obtain nitrilotriacetic acid.
일반 설명
Odorless white solid. Sinks in and mixes with water.공기와 물의 반응
Water Insoluble.반응 프로필
Nitrilotriacetic acid is incompatible with strong oxidizers, aluminum, copper, copper alloy and nickel. Nitrilotriacetic acid is also incompatible with strong bases.위험도
Possible carcinogen.건강위험
Toxicity and health hazard of these compounds are low. Contact with eyes causes irritation.화재위험
Flash point data for Nitrilotriacetic acid are not available; however, Nitrilotriacetic acid is probably combustible.Safety Profile
Confirmed carcinogen with experimental carcinogenic and neoplastigenic data. Poison by intraperitoneal route. Moderately toxic by ingestion. When heated to decomposition it emits toxic fumes of NOx,.잠재적 노출
Nitrilotriacetic acid (NTA) was used as a phosphate replacement in laundry detergents in the late 1960s. In 1971, the use of NTA was discontinued. The possibility of resumed use arose in 1980. NTA is now used in laundry detergents in states where phosphates are banned. NTA is also used as a boiler feed-water additive at a maximum use level of 5 ppm of trisodium salt. Currently, the remaining nondetergent uses of NTA are for water treatment, textile treatment; metal plating and cleaning; and pulp and paper processing.Carcinogenicity
Nitrilotriacetic acid is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals.운송 방법
UN2811 Toxic solids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required.Purification Methods
Crystallise it from water and dry it at 110o. [Beilstein 4 IV 2441.]비 호환성
Dust may form explosive mixture with air. Compounds of the carboxyl group react with all bases, both inorganic and organic (i.e., amines) releasing substantial heat, water and a salt that may be harmful. Incompatible with arsenic compounds (releases hydrogen cyanide gas), diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, and sulfides (releasing heat, toxic and possibly flammable gases), thiosulfates and dithionites (releasing hydrogen sulfate and oxides of sulfur). Attacks aluminum, copper, copper alloy and nickel.폐기물 처리
Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed.나이트릴로트라이아세트산 준비 용품 및 원자재
