    摘要： Compounds of the formula ##STR1## WHEREIN Z is alkyl with 2 to 6 carbom atoms, x is oxygen, NH or sulfur, n and m are integers from 2 to 6, r is zero or 1, R.sup.4, R.sup.5 R.sup.6 and R.sup.7 are hydrogen or methyl and R.sup.3 is methyl, ethyl or phenyl. They are obtained by reacting 1 mole of a compound of formulaZ--(X--H).sub.nwith n.multidot.m moles of an alkylencoxide or alkylenecarbonate of the formulas ##STR2## and n(m+r) moles of a phospholane of formula ##STR3## These compounds are used as flameproofing agents especially for pile carpets.

    摘要： A continuous process for the preparation of perfluorinated carbonyl fluorides from hexafluoropropene oxide (HFPO), in which HFPO is continuously oligomerized in a catalyst solution in devices which allow separation of the heavy product phase from the catalyst phase during the reaction, is described. Different oligomer distributions can be achieved by choice of the catalyst and different operating temperatures. The reaction itself takes place always in the substantial absence of the product which is formed, and achieves a considerable saving in time.

    摘要： A process for the preparation of the dimer of hexafluoropropene oxide (HFPO), in which the HFPO is dimerized in an aprotic polar solvent in the presence of a catalyst mixture, is described. The catalyst mixture is composed of a metal salt of the elements of the 1st transition metal series of the periodic table and of a tertiary diamine. By bringing in a molar ratio of metal salt to tertiary diamine in the range from 2:1 to 1:2, in particular 1:1, the selectivity for the dimeric compound is greatest, with high yields of the dimer being obtained.
