Preparation method of polyphenylacetylene copper catalyst

The invention discloses a preparation method of a polyphenylacetylene copper catalyst. The preparation method comprises the steps: completely dissolving bivalent soluble copper salt into methanol under the ultrasonic action, adding a certain amount of phenylacetylene, adding a reducing agent, carrying out stirring reaction at room temperature for 2 hours, centrifuging to remove methanol, washing with deionized water for three times, drying in vacuum for 8 hours at the temperature of 60 DEG C, and grinding to obtain the polyphenylacetylene copper catalyst. The preparation method is simple in process and simple and convenient to operate. 本发明公开了一种聚苯乙炔铜催化剂的制备方法，将二价可溶性铜盐在超声作用下完全溶解到甲醇中，加入一定量的苯乙炔，再加入还原剂，室温下搅拌反应2小时，离心除去甲醇，去离子水洗涤3次，60℃下真空干燥8小时，研磨即可得到聚苯乙炔铜催化剂，工艺简单，操作简便。
