Abstract
Organotrisiloxanes of the general formula <FORM:1119630/C3/1> where R1, R2 and R3 can be substituted or unsubstituted, saturated or olefinically or aromatically unsaturated hydrocarbon radicals and R represents an alkyl, cycloalkyl, aryl, aralkyl or an alkoxyalkyl radical, are prepared by (a) reacting a mixture, in an inert organic medium, of a diorganodichlorosilane of the formula R2R3SiCl2 and an organotrichlorosilane of the formula R1SiCl3 in a molar ratio of 2:1, with a mixture of water and a compound ROH in a molar ratio of 2 mols. of water and 3-20 mols. of ROH per mol. of the organo-trichlorosilane, (b) neutralizing the product to bromothymol blue with ammonia and (c) isolating the trisiloxane. The optimal concentration of the silane mixture is 40-80% by wt. based on the total weight of mixture. Inert organic medians include the usual aromatic aliphatic and cycloaliphatic hydrocarbons aliphatic ethers. The products may be used to produce mixed organosilicon resins by reaction with polyesters, epoxy resins, melamine-formaldehyde resins, ureaformaldehyde resins, alkyd resins, polyethers, phenol-formadehyde resins, cellulosic resins, polyurethanes or acrylic resins; or cohydrolysed and copolymerized with other organosilicon, organo-metallic and organo-metalloid monomers. The can be rearranged with organocyclopolysiloxanes or organopolysiloxanes in the presence of a suitable catalyst or used as additives in hot-vulcanized elastomers, as plasticizers or modifiers.
