1.1.2- trichlorotrifluoro-ethane

Mixtures of powdered titanium and trichloroethylene or 1,1,2-trichlorotrifluoro-ethane flash or spark under heavy impact. [Pg.1914]

Chemical abbreviations CT (carbon tetrachloride) CF (chloroform) MeCl (methylent chloride) TCA (tetrachloroethane or trichloroethane) Freon-113 (1,1,2-trichlorotrifluorO ethane) DBCP (l,2-dibromo-3-chloropropane) Lindane (y-hexachlorocyclohexane)... [Pg.48]

An unusual Friedel-Crafts reaction occurs between pentafluorobenzene and hexafluoropropene in the presence of antimony pentafluoride cis- and rranj-perfluoro(propenylbenzene), C,F6 CF CF CF3, and /rons-perfluoro-(1,3-diphenylpropene), CeF5-CF CF CF, C,Fs, are formed, probably via the carbocations (CF2i CFiiiCF, + and (C,Fs-CF CF--iiCF3)+. The reaction between pentafluorobenzene and 1,1,2-trichlorotrifluoro-ethane, also catalysed by antimony pentafluoride, proceeds with concomitant fluorination, and yields j3-chloroperfluoroethylbenzene, CjFj-CFj-CFjCl, and perfluorobibenzy . ... [Pg.365]

Trichlorotrifluoro-ethane (C2CI5F5) Used in low capacity centrifugal chiller packaged units. Operates with very low system pressures, high gas volumes. Also used as an intermediate in the manufacture of specialty lubricants. [Pg.322]

In the presence of excess zinc and acetic anhydride, 1,1,1 -trichlorotrifluoro-ethane reacts with aldehydes to yield trifluoromethyl substituted Z-alkenes as the major isomer [64], which has been utilized to prepare artificial pyrethroids containing the CH = C1CF3 moiety [65,66] (Scheme 23). [Pg.55]

Polymerization. Copolymers of tetrafluoroethylene/perfluoro(methyl vinyl ether) and the nitrile (1-4 mole ) have been prepared batch-wise in a stirred autoclave using an aqueous ammonium persulfate or ammonium persulfate-sodium sulfite redox couple system at 40°-100° C. The TFE/PMVE gas mixture was pressured, as required, to maintain the pressure and the nitrile pumped in solution in trichlorotrifluoro-ethane. After completion of the reaction, polymer was isolated from the latex (25-30 solids) by coagulation using ethanol and aqueous magnesium chloride solution. It was washed with alcohol/water solutions and dried at 70 °C in an oven under nitrogen. Mass balance indicated that most of the nitrile had been incorporated. [Pg.27]

The titration of ionizable chlorides with mercuric acetate solution in the presence of s-diphenylcarbazone as an indicator is used to determine chloride in trichlorotrifluoro-ethane. A visual appearance test to detect admixtures in halogenated solvents is based on the observation of suspended particles, sediment, turbidity and free floating water. ... [Pg.277]
