Bis(trifluoromethanesulfonyl)aniline is the organic compound with the formula C 6 H 5 N(SO 2 CF 3) 2. [1] It is a white solid. The compound is used to install the triflyl group (SO 2 CF 3). Its behavior is akin to that of triflic anhydride, but milder.
Triflyl group. In organic chemistry, the triflyl group (systematic name: trifluoromethanesulfonyl group) is a functional group with the formula R−SO 2 CF 3 and structure R−S(=O) 2 −CF 3.
Bistriflimidic acid. The conjugate acid of bistriflimide, which is frequently referred to by the trivial name bistriflimidic acid (CAS: 82113-65-3), is a commercially available superacid.
Preparation of the trifluoromethyltrimethylsilane was reported by Ingo Ruppert in 1984. [11] In 1989, Prakash and Olah first reported activation of TMSCF 3 by fluoride to perform nucleophilic trifluoromethylation of carbonyl compounds. [12]
Impact of a spray onto the target surface is expressed as the force/area, N/m 2 or lb/in 2. This value depends on the spray pattern distribution and the spray angle. Generally, solid stream nozzles or narrow spray angle flat fan nozzles are used for applications in which high impact is desired, such as cleaning.
For example, n-butyl triflate can be written as CH 3 CH 2 CH 2 CH 2 OTf. The corresponding triflate anion, CF 3 SO − 3, is an extremely stable polyatomic ion; this comes from the fact that triflic acid (CF 3 SO 3 H) is a superacid; i.e. it is more acidic than pure sulfuric acid, already one of the strongest acids known.
Mace is the brand name of an early type of aerosol self-defense spray invented by Alan Lee Litman in the 1960s. The first commercial product of its type, Litman's design packaged phenacyl chloride (CN) tear gas dissolved in hydrocarbon solvents into a small aerosol spray can, [1] usable in many environments and strong enough to act as a deterrent and incapacitant when sprayed in the face.
Flunisolide nasal spray is absorbed into the circulatory system (blood). [3] Corticosteroid nasal sprays may affect the hypothalamic-pituitary-adrenal axis function in humans. [7] After obtaining the desired clinical effect, the maintenance dose should be reduced to the smallest amount required to control the symptoms. The amount can be as low ...
