확인시험

  (1) 이 품목 0.1g을 물 10mL에 녹여 묽은초산으로 약산성으로 하고 질산은시액을 가하면 백색의 침전이 생긴다.

  (2) 이 품목의 수용액(1→20)은 확인시험법 중 나트륨염의 반응을 나타낸다.

정량법

  이 품목을 강열한 다음 약 500mg을 정밀히 달아 400mL 비이커에 넣고 물 100mL를 가한다. 이 용액의 pH를 pH미터를 사용하여 염산으로 3.8로 조정하고 황산아연시액[ZnSO₄•7H₂O 125g을 물에 녹이고 물로 1,000mL로 하고 염산으로 pH를 3.8로 조정한 액] 50mL를 가하고 2분간 방치한 후 pH 3.8이 다시 될 때까지 0.1N 수산화나트륨용액으로 유리된 산을 적정한다. 다만, 수산화나트륨용액을 가한 후 종말점 부근 가까이에서는 침전된 수산화아연이 다시 녹도록 정치시켜야 한다.

0.1N 수산화나트륨용액 1mL = 13.30mg Na₄P₂O₇

정의

개요

Sodium pyrophosphate, also called Tetrasodium pyrophosphate or TSPP is used in the laboratory as a buffering agent. The compound has been shown to be useful in the preparation of an EDTA-sodium pyrophosphate extraction buffer for microcystin analysis of soil samples. Tetrasodium pyrophosphate is an odorless, white powder or granules. It is used in water softener, buffering agent, thickening agent, dispersing agent, wool de-fatting agent, metal cleaner, soap and synthetic detergent builder, general sequestering agent, in electrodeposition of metals. It also acts as a tartar control agent in toothpaste and dental floss. In addition, it is used as a chelating agent in antimicrobial studies. It is also used as a food additive in common foods such as chicken nuggets, crab meat and canned tuna.

화학적 성질

Tetrasodium pyrophosphate is a white crystalline powder or colourless crystals with the formula Na4P2O7. It contains the pyrophosphate ion and sodium cation. Toxicity is approximately twice that of table salt when ingested orally. There is also a hydrated form, Na4P2O7.10H2O.

Tetrasodium pyrophosphate is used as a buffering agent, an emulsifier, a dispersing agent, and a thickening agent, and is often used as a food additive. It is widely used as an emulsifying salt (ES) in process cheese. Common foods containing sodium pyrophosphate include chicken nuggets, marshmallows, pudding, crab meat, imitation crab, canned tuna, and soy-based meat alternatives and cat foods and cat treats where it is used as a palatability enhancer. It is the active ingredient in Bakewell, the substitute for baking powder's acid component marketed during shortages in World War II. It is also used in some common baking powders.

용도

Pharmaceutic aid.
Tetrasodium pyrophosphate (Na4P2O7) is a non-toxic and biocompatible compound used as an electroactive media for exfoliation of the surface coating. It is also be used as an additive in the food industry.
Na4P2O7 can be used as an inorganic additive to improve the stability and electrochemical performance of redox flow batteries.

제조 방법

Tetrasodium pyrophosphate is formed when pure disodium hydrogen orthophosphate is heated to 500℃ for 5 hours. The product will contain better than 98 per cent Na4P2O7. Crystalline masses large enough for optical measurements are produced by heating in platinum to above the melting point of the tetrasodium pyrophosphate, 800°, and cooling slowly. Higher temperatures or longer heating times do not change the tetrasodium pyrophosphate, as this is the final product in the dehydration of disodium hydrogen orthophosphate.

일반 설명

Odorless, white powder or granules. Mp: 995°C. Density: 2.53 g cm-3. Solubility in water: 3.16 g / 100 mL (cold water); 40.26 g / 100 mL boiling water. Used as a wool de-fatting agent, in bleaching operations, as a food additive. The related substance Tetrasodium pyrophosphate decahydrate (Na4P2O7 0H2O) occurs as colorless transparent crystals. Loses its water when heated to 93.8°C.

반응 프로필

Tetrasodium pyrophosphate is basic. Reacts exothermically with acids. Incompatible with strong oxidizing agents. Decomposes in ethyl alcohol.

위험도

Toxic by inhalation.

건강위험

Tetrasodium pyrophosphate (TSPP) is of low toxicity, but the dust may be irritating to the eyes, upper respiratory tract, and skin. Mild to moderate skin and eye irritation have occurred with acute exposure to the dust.

Safety Profile

Poison by ingestion, intraperitoneal, intravenous, and subcutaneous routes. It is not a cholinesterase inhibitor. When heated to decomposition it emits toxic fumes of POx and Na2O.
