Bis-(N,N-dimethyl-N-carbodecyloxymethyl-N-ethylene-ammonium)-sulphide

The present invention relates to fluorosiloxane diols of the formula ##STR1## where: R.sub.F = OCF.sub.3, OC.sub.2 F.sub.5, OC.sub.2 F.sub.4 OCF.sub.3, C.sub.2 F.sub.4 OCF.sub.3, C.sub.3 F.sub.7,

Fluorosiloxane diols and method of producing same

The present invention relates to fluorosiloxane rubbers of the formula: ##STR1## wherein: R.sub.F = OCF.sub.3, OC.sub.2 F.sub.5, OC.sub.2 F.sub.4 OCF.sub.3, C.sub.2 F.sub.4 OCF.sub.3, C.sub.3 F.sub.7,

Fluorosiloxane rubbers and process for producing same

The invention relates to [perfluoroalkyl(alkoxy)phenyl]methyldichlorosilanes characterized by the general formula ##STR1## where: R.sub.F = OCF.sub.3 OC.sub.2 F.sub.5, OC.sub.2 F.sub.4 OCF.sub.3, C.sub.2 F.sub.4 OCF.sub.3, C.sub.3 F.sub.7 and also to a method of preparing them. The method according to the invention consists in that fluorobromo[alkyl(alkoxy)]benzenes having the general formula ##STR2## where: R.sub.F = OCF.sub.3 OC.sub.2 F.sub.5, OC.sub.2 F.sub.4 OCF.sub.3, C.sub.2 F.sub.4 OCF.sub.3, C.sub.3 F.sub.7 are treated with magnesium taken in a 5 - 20 per cent excess with respect to the stoichiometric quantity in a solution of absolute diethyl ether or absolute tetrahydrofurane at a temperature of 8.degree. - 60.degree. C. The resulting fluorine-containing magnesiumbromo[alkyl(alkoxy)]benzenes are treated with three-functional silanes -- methyltrichlorosilane -- taken in a 100 - 500 per cent excess with respect to the stoichiometric quantity, or with methylchlorodiethoxysilane, taken in the stoichiometric quantity or in a 50 per cent excess with respect to the stoichiometric quantity, at a temperature of 18.degree. - 60.degree. C. In the case of methylchlorodiethoxysilane, the resultant product is fluorine-containing [alkyl(alkoxy)phenyl]methyldiethoxysilanes which are treated with acetyl chloride taken in a 25 - 50 per cent excess with respect to the stoichiometric quantity, at a temperature of 40.degree. - 70.degree. C, in the presence of ferric chloride as a catalyst. The proposed [perfluoroalkyl(alkoxy)phenyl]methyldichlorosilanes can be used for preparing organofluosilicon lubricants, greases, sealing counds, rubber mixtures having high resistance to heat, frost, petrol and oils, that can be used in various fields of technology. The described method can be used to obtain the proposed end products in yields as high as 96 per cent of theory.
