| Abstract: | 1-Bromododecane was synthesized from n-dodecyl alcohol using byproduct hydrobromic acid from 1-bromoadamantan process as raw material in the presence of the concentrated sulfuric acid.The optimal conditions were as follow:the molar ratio of n-dodecyl alcohol,hydrobromic acid and concentrated sulfuric acid was 1:1.25:1.15,the reaction time was 3 h.No by-product was detected in the product by GC.The yield of 1-bromododecane was 92.5%,and the purity was 99.9%.The product was characterized by IR and index of refraction. |
