Abstract
Organo siloxanes are obtained by reacting a chlorosiloxane with a compound of the formula RR1OM, wherein R represents a methyl radical, R1 represents a methyl or phenyl radical and M represents an alkali metal, whereby the chlorine atom is replaced with a triorgano-siloxy group. In an example a polymer of the formula [(CH3)3SiO]3SiOSi[OSi(CH3)3]3 is obtained by reacting the sodium salt of trimethyl silanol with Cl3SiOSiCl3.ALSO:Organo silicon compounds of the general formula RR12OM, where R represents a methyl radical, R1 represents a methyl or phenyl radical and M represents an alkali metal are prepared by heating a reaction mixture of an alkali metal oxide, water and a compound of the general formula RR1Si-Alkoxy or RR12Si-O-SiR12R, wherein R and R1 have the above significance, and removing water from the reaction mixture, e.g. by distillation. A lower aliphatic alcohol having a boiling point below that of water and which is soluble in water may be included in the reaction mixture and bath, the alcohol and water are subsequently removed by distillation. The alkali metal oxide and water may be replaced with alkali metal hydroxide. In examples, the sodium and potassium salts of trimethyl silanol and methyldiphenyl silanol are prepared and in addition the double salts of methyl alcohol and sodium hydroxide with the sodium salt of trimethyl silonal and the double salt of potassium hydroxide and the potassium salt of trimethyl silanol are are obtained. The products of the invention may be reacted with silicon halides, e.g. silicon tetrachloride, mono-organo silicon trichloride, diorganosilicon dichloride or triorgano silicon chloride to replace each halogen atom with the triorganosiloxy group of the salt. The products of the invention may be similarly reacted with chlorosiloxanes, e.g. dichlorotetramethyldisiloxane may be reacted with an alkali metal salt of trimethyl silanol to give decamethyltetrasiloxane. In the examples a mixture of SiCl4 and Cl3Si-O-SiCl3 is reacted with trimethyl silanol sodium salt to give Si[OSi(CH3)3]4 and [(CH3)3Si-O-Si-[OSi(CH3)3]3, methyl silicon chloride is reacted with the sodium salt of trimethyl silanol to give CH3Si[OSi(CH3)3]3, diphenyldimethyl silanol sodium salt is reacted with trimethyl silicon chloride to give monophenylpentamethyldisilioxane.
