摘要:
A bimetallic catalyst supported on a transition metal oxide is described. A method to make and use the bimetallic catalyst is also described. A method for preparing supported bimetallic catalysts of coinage group metal and a combination of a coinage group metal and a platinum metal group is described. A method for direct synthesis of adipic acid (AA) adopting green catalytic oxidation route of cyclohexane (CH) using the bimetallic catalysts is described. The reaction to convert CH into AA in the presence of bimetallic catalyst is carried in an autoclave in the temperature range of 25 to 300° C. The CH conversion was over 21% with AA selectivity of 34% and ca. 63% selectivity of cyclohexanone and cyclohexanol together over Au—Pd/TiO2 bimetallic catalyst.
摘要:
The present invention relates to a method for preparing halogenated benzonitriles by vapor phase ammoxidation at a reaction temperature in the range of 300 to 500° C. in a fixed bed reactor using a three-component catalyst. More particularly, the method of the invention relates to a method for preparing 2,6-dichlorobenzonitrile (2,6-DCBN) from 2,6-dichlorotoluene (2,6-DCT) by vapor phase ammoxidation. The invention also relates to a three-component catalyst provided on a carrier and its use in a vapor phase ammoxidation reaction according to the invention. In addition, the invention provides a method for preparing the three-component catalyst.
