트리플루오로아세트 산 C화학적 특성, 용도, 생산
화학적 성질
Trifluoroacetic acid (TFA) is an analogue of acetic acid with the three hydrogen atoms replaced by three fluorine atoms. It has a vinegar-like odor and is a strong acid, a good solvent and has excellent reactive properties. The specific gravity of liquid TFA is 1.48 and it boils at 72 °C. Trifluoroacetic Acid is a solvent that is used in the production of pharmaceutical and agricultural chemicals as well as in many other specialized applications. Some of the more popular uses for TFA are as a silyl catalyst when derivatizing carbohydrates, as a reagent for purifying large peptides, as an ion pair reagent, and as an LC mobile phase additive.용도
Trifluoroacetic acid is an important building block in the synthesis of pharmaceuticals, agrochemicals and performance products. It is a precursor to many fluorinated compounds, and widely used in peptide synthesis and other organic transformations involving deprotection of t-BOC group. The combination of properties like solubility in most of the solvents, volatility, catalytic property, and strong acidity with non-oxidizing nature makes it a widely used reagent in organic synthesis. Trifluoroacetic acid can use as an ion pairing agent in liquid chromatography, as a solvent in NMR spectroscopy and as a calibrant in mass spectrometry. It is used as a catalyst in esterification reaction and condensation reaction and a protective agent for hydroxyl and amino.정의
ChEBI: Trifluoroacetic acid is a monocarboxylic acid that is the trifluoro derivative of acetic acid. It has a role as a reagent and a human xenobiotic metabolite. It derives from an acetic acid. It is a conjugate acid of a trifluoroacetate.일반 설명
Trifluoroacetic acid appears as a colorless fuming liquid with a pungent odor. Soluble in water and denser than water. Corrosive to skin, eyes and mucous membranes. Used to make other chemicals and as a solvent.공기와 물의 반응
Fumes in air. Soluble in water.반응 프로필
Trifluoroacetic acid is a strong acid; attacks many metals [Handling Chemicals Safely 1980. p. 935]. A 30% solution of hydrogen peroxide in Trifluoroacetic acid is often used to destructively oxidize aromatic rings in preference to the side chains. Explosions have occurred, if the excess peroxide is not catalytically destroyed, prior to removal of solvent, [Tetrahedron Lett., 1977, 1703-1704]. The reduction of amides of Trifluoroacetic acid with lithium aluminum hydride are dangerous at all phases of the process, explosions have occurred, [Chem. Eng. News, 1955, 33, 1368].건강위험
Trifluoroacetic acid is a highly corrosive substance. Contact of the liquid with the skin, eyes, and mucous membranes can cause severe burns, and ingestion can result in serious damage to the digestive tract. TFA vapor is highly irritating of the eyes and respiratory tract, and inhalation of high concentrations can lead to severe destruction of the upper respiratory tract and may be fatal as a result of pulmonary edema. Symptoms of overexposure to TFA vapor include a burning feeling, coughing, headache, nausea, and vomiting.Trifluoroacetic acid has not been found to be carcinogenic or to show reproductive or developmental toxicity in humans.
화재위험
Trifluoroacetic acid is not combustible. Nevertheless, the presence of trifluoroacetic acid at the site of a fire would be of great concern because of its high vapor pressure and extreme corrosiveness. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.Safety Profile
Poison by ingestion and intraperitoneal routes. Moderately toxic by intravenous route. Mildly toxic by inhalation. A corrosive irritant to skin, eyes, and mucous membranes. When heated to decomposition it emits toxic fumes of F-. Used as a strong organic acid catalyst.저장
trifluoroacetic acid should be stored in an acid cabinet away from other classes of compounds. Because of its high vapor pressure, fumes of trifluoroacetic acid can destroy labels on other bottles if the container is not tightly sealed.Purification Methods
The purification of trifluoroacetic acid, reported in earlier editions of this work, by refluxing over KMnO4 for 24hours and slowly distilling has resulted in very SERIOUS EXPLOSIONS on various occasions, but not always. This apparently depends on the source and/or age of the acid. The method is NOT RECOMMENDED. Water can be removed by adding trifluoroacetic anhydride (0.05%, to diminish water content) and distilling. [Conway & Novak J Phys Chem 81 1459 1977]. It can be refluxed and distilled from P2O5. It is further purified by fractional crystallisation by partial freezing and again distilled. Highly TOXIC vapour. Work in an efficient fume hood. [Beilstein 2 IV 458.]비 호환성
Mixing trifluoroacetic acid and water evolves considerable heat.폐기물 처리
Trifluoroacetic acid and waste material containing this substance should be placed in an appropriate container, clearly labeled, and handled according to your institution's waste disposal guidelines.트리플루오로아세트 산 준비 용품 및 원자재
