    摘要: A method for the hydrogenolysis of a phenyl alcohol to eliminate a hydroxyl group therefrom, the method comprising contacting a feed comprising the phenyl alcohol and a hydrogenating agent with a heterogeneous catalyst comprising copper and zirconium at a reaction temperature of less than 135 °C and wherein the amount of copper (calculated as CuO) is in the range of from 10 to 80 % by weight of the catalyst and the amount of zirconium (calculated as ZrO 2 ) is in the range of from 20 to 90 % by weight of the catalyst. A process for the preparation of an alkylene oxide is also disclosed.

    摘要: The invention relates to a process for the preparation of an alkanediol and a dialkyl carbonate comprising: (a) reacting an alkylene carbonate and an alkanol at a temperature of from 10 to 200 °C, at a pressure of from 5x10
    4 to 5x10
    6 N/m
    2 and in the absence of a transesterification catalyst, to obtain a mixture comprising hydroxyalkyl alkyl carbonate, alkanol and alkylene carbonate; (b) contacting the mixture comprising hydroxyalkyl alkyl carbonate, alkanol and alkylene carbonate with a transesterification catalyst at a temperature of from 10 to 200 °C and at a pressure of from 5xl0
    4 to 5xl0
    6 N/m
    2 , to obtain a mixture comprising the alkanediol and the dialkyl carbonate; and (c) recovering the alkanediol and the dialkyl carbonate from the mixture comprising the alkanediol and the dialkyl carbonate.
