性质描述: 低熔点结晶。熔点28.5℃,沸点210℃(1.33kPa),168-169℃(0.2kPa)。相对密度0.9848(20/4℃),折光率1.4631。溶于乙醇、乙醚、乙酸乙酯和石油醚,不溶于水。见光分解。
生产方法: 由十八醇与溴化氢反应而得。把醇加热到100℃,通入干燥的溴化氢,保持反应温度在100-120℃,至溶液不再吸收溴化氢为止。溴化物分层,取有机相加浓硫酸洗涤,分去酸液后的溴化物与等体积的90%甲醇混合,加氨水洗涤使溴化物呈碱性,再用90%甲醇洗涤,用无水氯化钙干燥。最后减压蒸馏,收集209-211℃(1.33kPa)馏分即为成品,产率90%。
用途: 有机合成中间体。

应用
1-Bromooctadecane is used in the preparation of shortened single-walled carbon nanotubes (s-SWCNTs). It is utilized to prepare octadecane in the presence of sodium borohydride as a catalyst. It is involved as a raw material for the preparation of dimethyldistearylammonium bromide, which is a bentonite modifier.

备注
Incompatible with strong oxidizing agents and strong bases. Store in a cool place. Keep the container tightly closed in a dry and well-ventilated place.
