Acetic acid sodium salt trihydrate

아세트산나트륨, 트리수화물 C화학적 특성, 용도, 생산

물성

화학식 CH3COONa· 분자량 82.04, 녹는점 324℃, 비중 1.528이다. 아세트산을 수산화나트륨 또는 탄산나트륨으로 중화하고, 증발·농축하여 냉각시키면 3수화염 CH3CO2Na·3H2O가 생긴다. 이 3수화염의 결정을 120∼250℃로 가열하면 무수염(無水 鹽)이 된다.

용도

약한 산과 강한 염기가 만드는 염이므로 수용액은 약한 알칼리성을 보인다. 완충용액의 조제, 염료의 매염제(媒染劑) 로 사용되며, 융해열이 크기 때문에 난방기구의 보온재로도 사용된다.

개요

Sodium acetate trihydrate is the trihydrate sodium salt oaf acetic acid.
In the food industry, sodium acetate is used as an acidity regulator, emulsifier, and preservative. It can give potato chips a salt and vinegar flavor. In pharmaceutical industry, it is used for replenishing lost electrolytes, as a diuretic, and in reusable heating pads and hand warmers. Sodium acetate trihydrate can be used to neutralize the industrial mineral acids discharge. In the textile and synthetic rubber production, it is used to neutralize sulfuric acids, facilitate aniline dye take up, and protect aniline day. In the leather industry, it is used as a buffering agent for leather tanning. Furthermore, sodium acetate trihydrate is used as buffers in the production of cosmetics and petroleum products and in electroplating industry.

화학적 성질

white to colourless crystals or powder

화학적 성질

Anhydrous salt is a colorless crystalline solid; density 1.528 g/cm3; melts at 324°C; very soluble in water; moderately soluble in ethanol. The colorless crystalline trihydrate has a density 1.45 g/cm3; decomposes at 58°C; is very soluble in water; pH of 0.1M aqueous solution is 8.9; moderately soluble in ethanol, 5.3 g/100mL.

화학적 성질

Sodium acetate occurs as colorless, transparent crystals or a granular crystalline powder with a slight acetic acid odor.

용도

Used as buffers.

용도

Sodium acetate is a mordant in dyeing. Other applications are in photography, as an additive to food, in purification of glucose, in preservation of meat, in tanning, and as a dehydrating agent. In analytical chemistry it is used to prepare buffer solution.

용도

In photography, analytical laboratory as buffer and in pharmaceutical.Sodium acetate trihydrate is used in various applications. It is used as a buffer of a pH range in between to 4.0 to 6.0. It is also used in the purification and precipitation of nucleic acids and in protein crystallization. It is used as a mordant dyeing, as a pickling agent in chrome tanning, as a neutralizer in waste streams containing sulfuric acid, in the textile industry and as a photoresist while using aniline dyes. It plays an important role to retard vulcanization of chloroprene in synthetic rubber production. It is a precursor to prepare ester from alkyl halide.

생산 방법

Sodium acetate is prepared by neutralization of acetic acid with sodium carbonate.

제조 방법

Sodium acetate is prepared by reacting sodium hydroxide or sodium carbonate with acetic acid in aqueous solution. The solution is evaporated to obtain hydrated crystals of sodium acetate.
NaOH + CH3COOH → CH3COONa + H2O
Na2CO3 + CH3COOH → 2CH3COONa + CO2 + H2O

일반 설명

Sodium acetate trihydrate can be obtained from the crystallization of sodium acetate in water. On heating at 75°C, it melts, while on heating above 120°C it loses water of crystallization and gets converted into anhydrous form. The hyperfine proton and 13C splittings have been evaluated by recording ESR spectra of its irradiated single crystals. ESR studies suggested the existence of trapped methyl radicals. Its crystals are monoclinic and its crystal structure has been investigated by photographic methods. Unit cell parameters were evaluated.

Pharmaceutical Applications

Sodium acetate is used as part of a buffer system when combined with acetic acid in various intramuscular, intravenous, topical, ophthalmic, nasal, oral, otic, and subcutaneous formulations. It may be used to reduce the bitterness of oral pharmaceuticals. It can be used to enhance the antimicrobial properties of formulations; it has been shown to inhibit the growth of S. aureus and E. coli, but not C. albicans in protein hydrolysate solutions. It is widely used in the food industry as a preservative. Sodium acetate has also been used therapeutically for the treatment of metabolic acidosis in premature infants, and in hemodialysis solutions.

Biochem/physiol Actions

Sodium acetate trihydrate (SAT) is a phase change material (PCM) that can be easily combined with the preparation of domestic hot water, space heating, solar heating, and radiant floor heating systems. The hydrated salt of SAT possesses high latent heat density and thus can be used for low-temperature heat storage.

Safety

Sodium acetate is widely used in cosmetics, foods, and pharmaceutical formulations, and is generally regarded as a nontoxic and nonirritant material.
A short-term feeding study in chickens with a diet supplemented with 5.44% sodium acetate showed reduced growth rates that were attributed to the sodium content.(9) Sodium acetate is poisonous if injected intravenously, is moderately toxic by ingestion, and is an irritant to the skin and eyes.
LD50 (rat, oral): 3.53 g/kg
LD50 (mouse, IV): 0.38 g/kg
LD50 (mouse, SC): 8.0 g/kg

저장

Sodium acetate should be stored in airtight containers.

비 호환성

Sodium acetate reacts with acidic and basic components. It will react violently with fluorine, potassium nitrate, and diketene.

Regulatory Status

GRAS listed. Accepted as a food additive in Europe. Included in the FDA Inactive Ingredients Database (injections, nasal, otic, ophthalmic, and oral preparations).
