  • Process for producing platinum alkenyl polysiloxane complex compounds, especially platinum divinyltetramethyldisiloxane
    Patent number: 6777566
    Abstract: A process for producing platinum alkenyl polysiloxane complex compounds, especially platinum divinyltetramethyldisiloxane, by reacting a haloplatinum compound with at least one alkenyl polysiloxane in the initial presence of platinum in the form of a platinum complex compound as an autocatalyst and in the initial presence of at least one base in an organic solvent or mixture of organic solvents that can be oxidized by the haloplatinum compound.
    Type: Grant
    Filed: October 16, 2002
    Date of Patent: August 17, 2004
    Assignee: W. C. Heraeus GmbH & Co. KG

  • Method for producing a cyanide-free solution of a gold compound that is suitable for galvanic gold baths
    Patent number: 6733651
    Abstract: A method for producing a cyanide-free solution of a gold compound that is suitable for gold electrodeposition baths. The method includes the steps of reacting at least one of a cysteine and a cysteinate with at least one of tetrachloroauric acid and a tetrachloroaurate in a first aqueous medium, separating a resulting precipitate from the first aqueous medium, and dissolving the precipitate in a second aqueous medium with elevation of the pH to 12.0-14.0.
