A method for preparing 2, 4, 6 - dicumylic

The invention relates to a preparation method of 2,4,6-tricumylphenol. The method comprises the following steps: phenol and a catalytic amount of aluminum powder have a reaction at certain temperature under nitrogen protection, a certain amount of ionic liquid is added to serve as a promoter after the aluminum powder disappears completely, then alpha-methylstyrene is added, HPLC (high performance liquid chromatography) is adopted to monitor a reaction, dilute sulphuric acid is added to terminate the reaction when the content of 2,4,6-tricumylphenol is not increased continuously, a reaction product is extracted with toluene, trace moisture in toluene is removed through atmospheric distillation, white crystals are dissolved out after cooling, and a crude product is obtained through filtering; the crude product is recrystallized for the second time by toluene, and 2,4,6-tricumylphenol with the content higher than 99% is obtained. The yield of the preparation method is about 64%, certain amount of phenol and a composite catalyst are supplemented to recrystallization mother liquor after the recrystallization mother liquor is subjected to solvent removal, reaction is performed continuously, and after the mother liquor is recovered, the yield can be higher than 95% in terms of the total feeding capacity.
