【Abstract】 1,1,3-trimethyl 3 phenylindane was synthesized from α methylstyrene with acid activated clay as catalyst The influenes of the reaction time,temperature and the quantity of catalyst on the yield of product were investigated,and the structure of the product was characterized by IR,MS and NMR The results showed when the temperature was 150℃ and the quantity of catalyst was 0 075 times of the quantity of α methylstyrene and the reaction time was 5h,the product yield was 89 06% The purity of the product could reach up to 99 9% by recrystallization in suitable solvent更多还原
