Abstract: Organosilane/silicate copolymers obtainable by reacting an organic phosphosilicon compound of the formula I (I) where n, X, Y, R1 and R2 have the meanings stated in the description, with an alkali metal silicate, radiator antifreezes containing these compounds, their use as corrosion inhibitors in radiator antifreezes based on glycol, a method of inhibiting corrosion of aluminum by aqueous cooling media, containing radiator antifreeze based on glycol, during the cooling of internal combustion engines, and the use of organic phosphosilicon compounds for stabilizing silicates.

Abstract: De-icing or anti-icing compositions for aircraft, essentially containing glycols, crosslinked polyacrylic acid, a nonionic surfactant composed of alkoxylated C10-C20-alcohols, corrosion inhibitors, a mixture of NaOH and KOH, an oxidation stabiliser and water. The compositions effect a smaller loss of lift owing to an improvement in the flow behaviour on the wings while maintaining a holdover time against refreezing of at least 30 min.

Abstract: Alkoxysilanes containing low levels of chlorine compounds are prepared by stepwise etherification of chlorosilanes with alcohols in liquid phase and removal of the resulting hydrogen chloride by reacting the alkoxysilane obtained, which still contains a small amount of chlorine compound, with a metal alkoxide in an amount which corresponds to a small stoichiometric excess based on the proportion of chlorine compound, and freeing the reaction product from the resulting salt.
