1. a kind of preparation method of Suzuki coupling reactions palladium-carbon catalyst, it is characterised in that comprise the following steps:

  • Cocoanut active charcoal is boiled activation by S1 through 5%-10% dust technologies, and then deionized water is washed to neutrality, drying;

    S2 meterings are added in the alcoholic solution containing phosphorus part and are impregnated through the cocoanut active charcoal after step S1 treatment, whereinDipping temperature is controlled at 50-60 DEG C, and solvent is removed afterwards, obtains loading the activated carbon of triphenylphosphine;

    The activated carbon of S3 load triphenylphosphines is beaten with the ammonia palladium of bicarbonate four with water, ethanol or ethylene glycol;

    S4 controls temperature at 80-100 DEG C, is passed through hydrogen reducing 3-4h, you can obtain palladium-carbon catalyst.
