  • Process for the enhancement of the cycle life of a zinc-chromium based catalyst in the synthesis of 2-methylpyrazine
    Publication number: 20020143180
    Abstract: The present invention relates to enhancement of the cycle life of a zinc chromium based catalyst used in the synthesis of 2-methylpyrazine by increasing the reaction temperature step-wise, starting from a low temperature, while monitoring the levels of total conversion and selectivity towards pyrazine. The catalyst can be regenerated after each cycle of use without substantial loss of activity.

  • Process for the microwave induced preparation of crystalline microporous titanium silicalite
    Patent number: 6387349
    Abstract: The present invention relates to a process for the microwave induced preparation of crystalline, microporous titanium silicalite. More particularly; the present invention relates to a process for the preparation of crystalline microporous titanium silicalite of the formula: xTiO2:(1−x)SiO2 wherein x is greater than 0.043 and less than or equal to 0.11. These silicalites, prepared under microwave irradiation have the same physico-chemical properties as titanium silicalite prepared by hydrothermal methods.
