Abstract
1-Bromododecane was synthesized from potassium bromide which is the by-product of synthesizing 2-hydroxy-4-n-dodecyloxybenzophenone and n-dodecyl alcohol using concentrated sulfuric acid as catalyst.By investigating the reaction condition,the experimental result showed that the optimal conditions are potassium bromide 0.1 mol,n-dodecyl alcohol 0.08 mol,concentrated sulfuric acid 6 mL,H2O 2.5 mL,refluxing for 4 h,the separated yield is high up to 92.5%.Raw product was analyzed by GC and no by-product was detected almost.Pure product was characterized by IR and index of refraction.
