| titleOfInvention | Process for the production of siliconfunctional polyorganosiloxanes |
| abstract | In the production of linear and branched equilibrated acyloxy-containing organopolysiloxanes by reacting a chlorosilane of the formula RaR'bSiCl(4-a-b) in which a is 0,1,2 or 3, b is 0,1,2 or 3, and a+b</=3, or a partial hydrolysate thereof, with at least one organosiloxane containing the components R2R''-SiO1/2, R R''-SiO, R''-SiO3/2 and SiO2 in which R and R'' each independently is H or an optionally halogen- or cyano-substituted monovalent hydrocarbon radical having up to 12 carbon atoms, and R'' is Cl, OH, H or an optionally halogen- or cyano-substituted monovalent hydrocarbon radical having up to 12 carbon atoms, in the presence of an equilibration catalyst, the improvement which comprises employing as the equilibration catalyst a salt of a fluorinated alkane sulphonic acid plus a monobasic carboxylic acid, the total number of Si-Cl groups exceeding the total number of Si-OH groups in the reactants and the monobasic carboxylic acid being present in at least about 1.1 times the molar amount of silicon-bound Cl atoms. Advantageously the salt of the fluorinated alkane sulphonic acid is the potassium salt of octafluorobutane sulphonic acid and it is used in about 0.3 to 0.7% by weight of the silicon compound reactants. The equilibration is effected at a temperature up to about 135 DEG C., and the monobasic carboxylic acid is acetic acid. |
