  • Distillative separation of liquid mixtures containing aliphatic alcohols
    Patent number: 4383893
    Abstract: Liquid mixtures containing aliphatic alcohols are separated, by distillation, into a higher-boiling alcohol-containing fraction and a lower-boiling fraction containing the other liquids, by carrying out the fractionation in the presence of water and of an alkanal and, over about 3/4 of the column height, in the presence of a non-volatile or only slightly volatile acid.
    Type: Grant
    Filed: April 20, 1981
    Date of Patent: May 17, 1983
    Assignee: BASF Aktiengesellschaft
    Inventors: Gerd Kaibel, Horst Hartmann, Waldhelm Hochstein, Franz-Josef Mueller
  • Removal of organic iodine compounds from acetaldehyde
    Patent number: 4383894
    Abstract: A process for separating off organic iodine compounds from acetaldehyde by subjecting the acetaldehyde to azeotropic distillation with a hydrocarbon boiling at from 25.degree. to 55.degree. C. under atmospheric pressure.

  • Preparation of aromatic silanes
    Patent number: 4363925
    Abstract: Aromatic silanes are prepared by reacting an aromatic halogen compound with a disilane in the presence of a palladium complex and a phosphite or phosphine.The aromatic silanes obtainable by the process of the invention are valuable intermediates for the preparation of drugs, dyes and pesticides.

  • Activation of substrates for electroless metallization with zero valent palladium complex
    Patent number: 3993807
    Abstract: A process for metallizing substrates by activation of the substrate by deposition of palladium from a palladium complex, followed by electroless metallization. The palladium is deposited on the substrate by dipping the substrate into a solution of a palladium(O) complex and decomposing this complex at from 100.degree. to 300.degree. C.With this method it is possible to effectively activate substrates which are attacked by acid or alkali or swollen by organic solvents.
