  • Patent number: 4946976
    Abstract: A Group IIA metal-Group IIIA metal-silicon substantially homogeneous liquid alkoxide is prepared from a reaction mixture of a Group IIA metal, a Group IIIA metal, a silicon tetraalkoxide, and a liquid defined by the formula ROR' where R is an alkyl group and R' is hydrogen or an alkyl group. The alkoxide can then be hydrolyzed, azeotropically distilled, dried, milled, and calcined to produce a ceramic powder. Advantageously, the ceramic powder can be compacted and sintered at relatively low temperatures which enable it to be used in electrical applications where high sintering temperatures would be deleterious.

  • Patent number: 4910348
    Abstract: Polyfluoroenolates, R.sup.1 CX.dbd.CR.sup.2 OM (R.sup.1 is F or a perfluoroalkyl group, R.sup.2 is a perfluoroalkyl group, X is F, Cl or Br), are easily formed at good yields by dehydrohalogenation reaction of polyfluoroalcoholates, R.sup.1 CXY--CR.sup.2 HOM (Y is F, Cl or Br), with a strong base such as, e.g., an alkyl metal or an aryl metal. A typical example of the polyfluoroenolates is lithium pentafluoro-2-propenolate which is obtained from hexafluoro-2-propanolate. A polyfluoroenolate of the above general formula can be converted into another polyfluoroenolate having an alkyl or aryl group in place of the halogen X by reaction with an alkyl or aryl metal.

  • Patent number: 4816594
    Abstract: The present invention relates to aluminate coupling agents, their synthesis and applications. Metallic aluminum is reacted with lower alcohols, then reacted with selected longer chain alcohols, phenols, carboxylic acids etc., satisfied the coordination number of aluminum to give aluminate coupling agents having good hydrolytic stability and lower associativity. They can be used directly as typical coupling agents in processing of composition products such as plastics, rubber, coatings and laminates etc., and as adhesive promoter or primer to treat fillers, pigments and various materials in order to improve the processing and the quality of products, to increase the dosage of filler, to develop new products, to reduce energy consuming and cost of products.

  • Patent number: 4670573
    Abstract: There are disclosed improved methods for preparing metal alkoxides from metals and alcohols. The methods involve dry-grinding the metal in an inert atmosphere prior to the addition of the alcohol. When an activator is used, it is usually ballmilled with the metal. Higher yields are obtained, particularly when the metal and alcohol are not very reactive absent an activator. Typical metals are those from Groups 2A, 2B, 3A, and 3B, particularly aluminum, magnesium, and yttrium. Typical alcohols are those which contain up to 16 carbon atoms, particularly those containing 4 or more carbon atoms.
