摘 要:The syntheis of diphenyletylane with xylol and styrene as reactants and solid superacid SO42-/TiO2 doped rare-earth metal ion La3+ as a catalyst was *** results showed that the optimal conditions were using 1% of catalyst with the molar ration of xylol to styrene being 7.5:1,at temperature of 140℃ for 3 h;The yield of diphenylethylane under such conditions was about 97.5%.
