과황산암모늄 C화학적 특성, 용도, 생산
순도시험
(1) 용상 : 이 품목 1g을 물 10mL에 녹일 때, 그 액은 무색으로서 탁도는 거의 징명 이하이어야 한다.
(2) 비소 : 이 품목을 비소시험법에 따라 시험할 때, 그 양은 4.0ppm 이하이어야 한다.
(3) 납 : 「메타인산나트륨」의 순도시험 (2)에 따라 시험한다(2.0ppm 이하).
확인시험
(1) 이 품목 0.5g에 수산화나트륨시액 5mL를 가하여 가열하면 암모니아냄새가 있는 가스를 발생하고 이 가스는 물에 적신 적색리트머스지를 청색으로 변화시킨다.
(2) 묽은황산 5mL에 황산망간용액(1→100) 2~3방울을 가하고 이에 질산은시액 1방울 및 이 품목 0.2g을 가하여 가온하면 액은 홍색을 나타낸다.
정량법
이 품목 약 1.5g을 정밀히 달아 물에 녹여 250mL로 하고 그 중 50mL를 취하여 0.1N 황산제일철암모늄용액 40mL 및 인산 5mL를 가한 다음 과잉의 황산제일철암모늄을 0.1N 과망간산칼륨용액으로 적정한다. 따로 같은 방법으로 공시험을 한다.
0.1N 황산제일철암모늄용액 1mL = 11.41mg (NH4)2S2O8
강열잔류물
이 품목은 처음에 천천히 가열하고 항량이 될 때까지 강열할 때, 그 잔류물은 0.2% 이하이어야 한다.
개요
Persulfates are strong oxidizing agents widely used in the production of metals, textiles, photographs, cellophane, rubber, adhesive papers, foods, soaps, detergents and hair bleaches. Ammonium persulfate is used as a hair bleaching agent. It may induce irritant dermatitis, contact urticaria and allergic contact dermatitis and represents a major allergen in hairdressers.화학적 성질
Ammonium persulfate is a colorless or white crystalline solid.용도
Ammonium Persulfate is a bleaching agent for food starch that is used up to 0.075% and with sulfur dioxide up to 0.05%.일반 설명
A white crystalline solid. A strong oxidizing agent. Does not burn readily, but may cause spontaneous ignition of organic materials. Used as a bleaching agent and as a food preservative.공기와 물의 반응
Soluble in water.반응 프로필
Ammonium persulfate is a potent oxidizing agent. A powdered mixture with aluminum and water can explode [NFPA 491M 1991]. A mixture with sodium peroxide will explode if subjected to friction (crushing in a mortar), heating, or if a stream of carbon dioxide is passed over Ammonium persulfate [Mellor 10:464 1946-47]. Acidic solutions dissolve iron violently, [Mellor, 1947, Vol. 10, 470].위험도
Fire risk in contact with reducers.건강위험
Inhalation produces slight toxic effects. Contact with dust irritates eyes and causes skin rash.색상 색인 번호
Persulfates are strong oxidizing agents widely used in the production of metals, textiles, photographs, cellophane, rubber, adhesive papers, foods, soaps, detergents, and hair bleaches. Ammonium persulfate is used as a hair bleaching agent. It may induce irritant dermatitis, (mainly) nonimmunologic contact urticaria, and allergic contact dermatitis and represents a major allergen in hairdressers. People reacting to ammonium persulfate also react to other persulfates such as potassium persulfate.Safety Profile
Poison by intravenous and intraperitoneal routes. Moderately toxic by ingestion. A powerful oxidizer that can react vigorously with reducing agents. Releases oxygen when heated. Mxtures with sodium peroxide are explosives sensitive to friction, heating above 75℃, or contact with CO2 or water. Mixtures with (powdered aluminum + water) or (zinc + ammonia) are explosive. Violent reaction with iron or solutions of ammonia + silver salts. Solution with sulfuric acid is a strong oxidzing cleaning solution. When heated to decomposition it emits toxic fumes of SO,, NH3, and NOx.잠재적 노출
It is used as a bleaching agent, in photographic chemicals, and to make dyes. It is also used as an ingredient of polymerization catalysts.운송 방법
UN1444 Ammonium persulfate, Hazard Class: 5.1; Labels: 5.1-OxidizerPurification Methods
Recrystallise it at room temperature from EtOH/water. It gradually loses NH3 on exposure to air. Its solubility is 0.5g/mL at 20o, and 2g/mL at 100o.비 호환성
Decomposes in water and moist air, forming oxygen gas. A strong oxidizer; reacts with reducing agents; organic and combustible materials. Incompatible with heat, sodium peroxide (produces a friction-, heat-, and water-sensitive explosive); aluminum powder.폐기물 처리
May be treated with large volumes of water, neutralized and flushed to sewer. This applies to small quantities only.과황산암모늄 준비 용품 및 원자재
