After a mixture of 172 g of terphenyl, 860 ml of benzene, and 353 g of acetyl chloride was cooled to -5° C., it was added with a total of 200 g of anhydrous aluminium chloride in few instalments, and subjected to reaction at -5° C. for 1 hour and further at 10° C. for 1 hour. The solid materials thus formed were separated by filtration, washed with a total of 4 liter of methanol in few instalments, and then recrystallized from chloroform to obtain 121 g of 4-acetyl-p-terphenyl, 2. The yield was 59%.
