The synthesis of n-octyl bromide with hydrobromic acid and n-octyl alcohol as reactants and rare earth solid super acid S2O82-/ZrO2-SiO2-Sm2O3as catalyst is studied.The results show that the optimum conditions should...
A novel type of rare earth promoted solid super acid catalyst,S2O82-/ZrO2-SiO2-Sm2O3,was prepared by a special precipitation method,and ammonia persulfate was used as promoter instead of sulfuric acid.The catalysts we...
