Abstract
Trifluoronitrosomethane CF3NO obtained by pyrolysis of CF3COONO (see Division C2) is copolymerized with tetrafluoroethylene at - 30 DEG C. The product dissolves in tri-perfluorobutylamine. Specifications 763,673, 784,727 and 1,008,194 are referred to.ALSO:Halo-acyl nitrites (RCOONO) are prepared by reacting, under anhydrous conditions at a temperature of - 80 DEG to + 110 DEG C., an anhydride of a carboxylic acid containing at least one halogen atom on each a -carbon atom with a nitrous acid derivative, such as N2O3 or a nitrosyl halide. When heated the products lose CO2 to give RNO. Specified acids of which the anhydrides are used are those of the formulae X(CCl2)nCOOH, X(CF2)nCOOH, RfOCF2CH2COOH, Z.CFCl(CF2CFCl)mCF2COOH, Z(CF2CFCl)mCF2COOH and CF2Cl.CF2(CFClCF2)mCFCl.COOH, where X is H, F or Cl, Z is perhalomethyl of total atomic weight not greater than 146.5, or is -COON, Rf is C1- 8 perfluoroalkyl, n is 1-1 and m is 0-5. Examples are given of the production of the haloacyl nitrites, and CF3NO is obtained by pyrolysis of CF3COONO. Specifications 763,673, 784,727 and 1,008,194 are referred to.ALSO:Nitrogen sesquioxide N2O3 is prepared by (1) sparging NO into liquid or partially solidified N2O4, and (2) mixing streams of gaseous NO and O2. Specifications 767,673, 784,727 and 1,008,194 are referred to.
