| Production method | Obtained by bromination of hexadecanol: Put hexadecanol into a reaction pot, stir, heat, melt, and add red phosphorus. At 100 ℃, stir thoroughly while adding bromine dropwise. Control the temperature between 120-130 ℃ and complete the dropwise addition after about 6 hours. Continue the reaction and remove all hydrogen bromide. Cool to below 50 ℃, add saturated and sodium chloride, stir and wash, let stand for layering, separate the lower waste liquid, wash with water until neutral, distill, collect the fraction at 220-230 ℃ (2kPa), and obtain 1-bromohexadecane. |
