Summary:The invention discloses a preparation method of a rubidium/cesium extractant 4-tert-butyl-2-(alpha-methylbenzyl)phenol (t-BAMBP), which comprises the following step: carrying out Friedel-Crafts reaction on raw materials 4-bert-butyl phenol and styrene by using phosphoric acid and acid anhydride as a catalyst to synthesize the 4-tert-butyl-2-(alpha-methylbenzyl)phenol in a simple high-yield mode. The method is characterized in preparation of the catalyst; the phosphoric acid and acid anhydride firstly react under certain conditions to obtain a mixed acid catalyst, and the 4-bert-butyl phenol and styrene are added to react to finally obtain the 4-tert-butyl-2-(alpha-methylbenzyl)phenol at high yield. The product yield of the method can reach 71%, and the product purity is greater than 95%; and the method has the advantages of simple and accessible raw materials, simple synthesis technique, higher product quality and lower production cost.
