  • Patent number: 8299408
    Abstract: A system for heating wood products is provided. The system may include a launcher. The launcher may include a waveguide bend and a waveguide. The launcher may have one or more slots along the longitudinal axis of the waveguide. The slots may be slanted at an angle with respect to the longitudinal axis and spaced at an interval along the longitudinal axis. Moreover, the system may include windows covering the slots. The windows may serve as a physical barrier and allow electromagnetic energy to be transferred from the launcher to the wood product. The launcher and wood products may be contained in a microwave reactor (also referred to as a chamber) to heat the wood products.

  • Patent number: 7928267
    Abstract: Novel trivalent organophosphite ligands having the structure of general formula (I): wherein R is an alkyl or aryl group containing 1 to 30 carbon atoms; Ar1 and Ar2 are aryl groups containing 4 to 30 carbon atoms; R1 to R6 are H or alkyl or aryl hydrocarbon radicals containing 1 to 40 carbon atoms; and X is a connecting group or a simple chemical bond, were developed and found to be very active for hydroformylation processes for ethylenically unsaturated substrates. Catalyst solutions prepared from these ligands with a Rh metal show an unusual “ligand acceleration effect” for simple alkenes, i.e., the hydroformylation activity increases as the concentration of ligand increases, and are capable of producing linear or branched aldehydes under typical hydroformylation conditions.

  • Patent number: 7659432
    Abstract: Mixed ketones are prepared from a mixture of carboxylic acids in a process with high selectivity by using an improved catalyst. The catalyst contains zirconium dioxide or zirconium dioxide and titanium dioxide, and a Group 1 or 2 metal silicate or phosphate salt. The new catalyst is more selective toward the formation of the mixed ketone, as opposed to a symmetrical ketone.
