  • Patent number: 4571290
    Abstract: A process for the selective oxidation of olefins comprises the steps of forming a suspension of semiconductor powder in a solvent media, adding an olefin to the solvent media in the presence of an oxidant to form a mixture and, photochemically activating the mixture with illumination having an energy at least equal to the band gap of the semiconductor powder wherein the selectivity is controlled by the selection of A, of the solvent and of the oxidant. The process is one carried out at about ambient temperature and with gentle agitation. The semiconductor powder has the general formula A.sub.x B.sub.y C.sub.z where A is selected from Bi, Sn, Pt, Pd, Cu, Fe, W, V, Sb, Mo, Ru or Ag and mixtures thereof; B is Te, Sb, Ti, Cd, Mo, V or W and mixtures thereof; C is O or S; x equals 0 to 5; y equals 1 to 3; and z is a number necessary to satisfy the other elements, and is optionally metallized by an element selected from Pt, Pd, Cu or Ag.

  • Patent number: 4536640
    Abstract: An apparatus for deposition of coatings upon substrates generates a non-local thermal equilibrium arc plasma at the relatively high pressure of at least approximately 1 atmosphere. A closed chamber (25) is defined by a cylindrical anode (11) and annular housings (21, 22) carrying transparent end plates (23, 24). A pencil-shaped cathode (12) is passed through one end plate (23 or 24) coaxially into chamber (25) so that its tapered end (20) is spatially proximate to an exit orifice (44) centrally located in anode (11). Gas ports (30, 31) permit the introduction of a preselected gaseous environment at the desired pressure into chamber (25). A low-current arc is struck between anode (11) and cathode (12) establishing the desired plasma. Two coils (33, 34) are coaxially placed radially outward of both ends of the chamber in a Helmholtz coil configuration to generate a uniform magnetic field in chamber (25) and induce rotation of the arc plasma.
