  • Publication number: 20080153692
    Abstract: The present invention relates to a method of producing a catalyst or pre-catalyst suitable for assisting in the production of alkenyl alkanoates. The method includes contacting a modifier precursor to a support material to form a modified support material. One or more catalytic component precursors (palladium or gold) may be contacted to the modified support material. The atomic ratio of gold to palladium is preferably in the range of about 0.3 to about 0.90. The support materials with the catalytic component may then be reduced using a reducing environment. A composition for catalyzing the production of an alkenyl alkanoates including a modified support material with palladium and gold is also included within the invention. Catalysts of the present invention may be used to produce alkenyl alkanoates in general and vinyl acetate in particular and are useful to produce low EA/VA ratios while maintaining or improving CO2 selectivity.

  • Patent number: 7292500
    Abstract: A read activity detector circuit for use in a random access memory array includes a plurality of synchronizer circuits operative to receive a plurality of respective reference clock signals having a frequency that is substantially the same as a core reference clock and having different phases relative to one another. Each of the synchronizer circuits, in response to a first control signal presented thereto, generates an output signal having a rising edge or a falling edge which is substantially aligned to a rising edge or a falling edge of the reference clock signal corresponding thereto. The activity detector circuit further includes a controller operative to receive the respective output signals from the plurality of synchronizer circuits and to generate an output signal as a function thereof which is indicative of data to be read from the random access memory array.
