    • This invention relates to ion-pair-containing siloxane compounds that are extremely effective as surface tension depressants. The compounds of the present invention contain both anionic and cationic substituents and can be formed by metathesis reactions between metallic salts of anionic silicone or organic surface-active compounds and halide salts of quaternary ammonium silicone or organic surface-active compounds. The compounds of the invention are relatively pH insensitive when compared to siloxanes bearing anionic and cationic substituents that are formed by proton transfer. Thus, the organosilicon compounds of the invention will remain stable despite changes in pH of the mixture in which they are present.

    • The invention comprises sulphate-containing siloxanes of the formulae wherein R1 is Cl-6 alkyl radical or trialkylsilyl radical, at least 50% of R1 consisting of the latter, R is a monovalent hydrocarbon or halohydrocarbon radical, M is an alkylene radical which bridges the silicon and oxygen atoms through at least three carbon atoms, each X is a hydrogen atom, or one equivalent of a metal or NHR13, wherein R1 is a hydrogen atom or a hydrocarbon or substituted hydrocarbon radical; and x=0 to 1, y=2 to 3, z=1 to 10 and x+y=3. R is preferably an C1- 4 alkyl radical, and M is preferably (CH2)3 or (CH2)4. Specified X radicals are Na, K, Ca, Al, Zr and those derived from ammonia, hydrazine, amines, polyamines, alkanol amines, heterocyclic amines and quaternary ammonium compounds; many examples are given. Compounds of Formulae (I) and (II) are prepared by reacting an organo - silicon compound RxYySi(MOCOR)4-(x+y)with chlorosulphonic acid yielding a compound of the unit formula this is reacted with a hexa-alkyl disiloxane, R3SiOSiR3, and the R3SiY produced distilled off yielding SiRx(R3SiO)y(MO-SO2.OSiR3) which is further heated giving compounds of Formula (II). The products are subjected to hydrolysis or alcoholysis optionally followed by neutralization. A typical Example (1) describes the preparation of and the disiloxane obtained by replacing one (CH3)Si group by C2H5. Uses.-In lacquers and varnishes as spreading agents, antistatic agents, preventing glass fogging, wetting agent, in polyurethane foams, glass fibre finishing agents.
