| titleOfInvention | Method of obtaining flurohalogenethers |
| abstract | FIELD: chemistry. n SUBSTANCE: invention pertains to the method of obtaining (per)fluorohalogenethers with general formula (I): (R) n C(F) m OCAF-CA'F 2 (I), which are used in obtaining fluorinated vinyl ethers, which are a class of essential monomers for obtaining various polymers. In formula (I) A and A' are the same or different, represent Cl or Br or one of A and A' represents hydrogen, and the other a halogen, chosen from CI, Br; R=F or fluorinated, preferably perfluorinated, substitute, chosen from the following groups: linear or branched C 1 -C 20 alkyl; C 3 -C 7 cycloalkyl; C 6 -C 10 aromatic group, C 6 -C 10 arylC 1 C 20 alkyl, C 1 -C 20 alkylC 6 -C 10 aryl, or C 6 -C 20 alkyl C 5 -C 10 hetertocycle; if R represents fluorinated or perfluorinated alkyl, cycloalkyl, arylalkyl, alkylaryl, then it can optionally contains in a chain, one or more oxygen atoms; if R represents a fluorinated substitute, it can optionally contain one or more H atoms and/or one or more halogen atoms, except F; n is an integer, equal to 1 or 2; m is an integer, equal to 3-n. The method involves reaction of carbonyl compounds with formula (II): (R) p C(F) q (O) (II), where p is an integer, equal to 1 or 2; q is an integer, equal to 0 or 1, under the condition that, if p=2, then q=0; if p=1, then q=1; in the liquid phase with elementary fluorine and olefinic compounds with formula (III): CAF=CA'F (III). n EFFECT: invention allows obtaining fluorohalogenethers with improved selectivity. n 8 cl, 9 ex |
