Abstract
The 1-bromo-n-dodecane i synthesized using 1-dodecanol and hydrobromic as raw material,solid superacid SO_4~(2-)/ZrO_2 as catalyst.The effect of preparing condition of solid superacid catalyst and reaction condition on synthesizing 1-bromo-n-dodecane are discussed by orthogonal experiment.The best preparation conditions of solid superacid catalyst SO_4~(2-)/ZrO_2 were:concentration of sulphuric acid was 0.5 mol/L,impregnating time 0.5 h,650 ℃ roasting for 2 h.The conditions for synthesizing 1-bromo-dodecane were as follows; 110 ℃ reaction for 6 h,molar ratio n(C_(12)H_(25)OH)∶n(HBr)=1.0∶(2.0),mass ratio of catalyst m(C_(12)H_(25)OH)∶m(cat)=1.000∶0.150,the yield of 1-bromo-n-dodecane was 72.0%.
