트리플루오로메탄술폰산은 펩티드 보호기를 제거하고 이성질체화와 중합을 촉매하기 위해 중합체에 대한 용매로 사용된다. 그 에스테르는 우수한 알킬화제이다. 무수물 (F3C-SO2)2O는 무색, 흡습성, 독성 액체이고(끓는점 84℃), 트리플루오로메탄술포닐기(triflate기)를 도입하기 위해 제조 화학에서 사용된다.
화학적 성질
Clear very light yellow liquid. Smoke in the air, easy to absorb water to form a hydrate. It is easily soluble in water, releases a lot of heat, and hydrolyzes to generate trifluoromethane (CHF3) and sulfuric acid.
용도
Trifluoromethanesulfonic acid acts as a catalyst for esterification reactions and an acidic titrant in nonaqueous acid-base titration. It is useful in protonations due to the presence of conjugate base triflate is non nucleophilic. It serves as a deglycosylation agent for glycoproteins. In addition, it is a precursor and a catalyst in organic chemistry. It reacts with acyl halides to prepare mixed triflate anhydrides, which are strong acylating agents used in Friedel-Crafts reactions. It acts as a key starting material for the preparation of ethers and olefins by reacting with alcohols as well as to prepare trifluoromethanesulfonic anhydride by dehydration reaction.
정의
ChEBI: Trifluoromethanesulfonic acid is a one-carbon compound that is methanesulfonic acid in which the hydrogens attached to the methyl carbon have been replaced by fluorines. It is a one-carbon compound and a perfluoroalkanesulfonic acid. It is a conjugate acid of a triflate.
일반 설명
Trifluoromethanesulfonic acid is a strong organic acid. It can be prepared by reacting bis(trifluoromethylthio)mercury with H2O2. On mixing with HNO3, it affords a nitrating reagent (a nitronium salt). This reagent is useful for the nitration of aromatic compounds. Its dissociation in various organic solvents has been studied.
Safety Profile
A corrosive irritant to
the skin, eyes, and mucous membranes. A
strong acid. Violent reaction with acyl
chlorides or aromatic hydrocarbons evolves
toxic hydrogen chloride gas. When heated to
decomposition it emits toxic fumes of Fand
SOx. See also FLUORIDES.
