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.
Liquid–feed flame spray pyrolysis (LF-FSP) is one of the most recent iterations in flame spray pyrolysis (FSP) powder production technology. [ 1 ] [ 2 ] FSP produces metal oxide powders from highly volatile gaseous metal chlorides that are decomposed/oxidized in hydrogen-oxygen flames to form nano-oxide powders .
A palladium acetate catalysed reaction described in 1982 used zinc powder with the main intermediate believed to be CF 3 ZnI with Pd(0) is the active catalyst. [ 35 ] [ 36 ] The first copper catalysed coupling was reported in 2009 and based on an iodoarene , a trifluoromethylsilane , copper iodide and 1,10-phenanthroline . [ 37 ]
The most common type of spray dryers are called single effect. There is a single source of drying air at the top of the chamber (see n°4 on the diagram). In most cases the air is blown in the same direction as the sprayed liquid (co-current). A fine powder is produced, but it can have poor flowability and causes a lot of dust.
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.
Cold spray additive manufacturing (CSAM) (also called cold spray 3D printing) is a particular application of cold spraying, able to fabricate freestanding parts or to build features on existing components. During the process, fine powder particles are accelerated in a high-velocity compressed gas stream, and upon the impact on a substrate or ...
The diameter of the powder used is relative to the density (g/m 2) of the stock (paper or board) being printed. For 150 g/m 2 paper the ideal anti-set-off spray powder would be 15 μm in diameter, for 200 g/m 2 20 μm, through to 70 μm for heavy board (700 g/m 2). Most manufactures of spray powder offer both coated and uncoated powders.
