  • Patent number: 4609752
    Abstract: A continuous process for the preparation of alkoxypolysiloxane in which silane or a silane mixture and a mixture of hydrogen chloride-containing alcohol and water is fed continuously into the lower region of preferably cylindrical stirred reactor, the reaction product formed together with excess hydrogen chloride-containing alcohol is drawn off continuously after residence time of 30 to 180 minutes at the upper end of the reactor and the undissolved, gaseous portion of hydrogen chloride is carried off at the head of the reactor, the temperature of the reaction mixture or the reaction product, as it flows through the reactor, being raised from a range of -17.degree. to +30.degree. C. to range of +30.degree. to +80.degree. C., the temperature gradient having to be at least 10.degree. C.

  • Patent number: 4564665
    Abstract: Polysiloxanes of specified molecular weight and molecular weight distribution are effective anti-foam agents for reducing foaming in crude oil/gas separators. They are particularly useful in breaking microgas dispersions.The polysiloxanes, preferably polydimethyl siloxane, contain not more than 10% by weight of components of molecular weight 50,000 and lower, at least 15% by weight of components of molecular weight 200,000 and higher and not more than 6% by weight of components of molecular weight 370,000 and higher, molecular weights being expressed as polystyrene equivalent molecular weights.

  • Patent number: 4137179
    Abstract: A new method for producing a stable, aqueous preparation of compounds which are organosiloxanes having amino groups attached to the silicon atoms which are used for the shrink-proofing of wool which preparations contain silanes which may be aminodi- or trialkoxysilanes is disclosed. Composition and the method of treatment of wool are also disclosed. Wool treated with the preparations exhibit excellent decreased shrinkage as well as an absence of felting.
