使用
1-Bromohexadecane is used in the preparation of soluble carbon nano-onions by covalent functionalization with hexadecyl chains. It is also used to synthesize [2-(methacryloyloxy)ethyl]dimethylhexadecylammonium bromide monomer, required for the synthesis of novel methacrylate based adsorbents.
使用
1-Bromohexadecane has been used:
in the preparation of soluble carbon nano-onions by covalent functionalization with hexadecyl chains
as extraction solvent in determination of endocrine-disrupting phenols (EDPs) in water samples by ultrasound-assisted emulsification microextraction (MS-USAEME) method
in the preparation of [2-(methacryloyloxy)ethyl]dimethylhexadecylammonium bromide monomer, required for the synthesis of novel methacrylate based adsorbents
in the synthesis of surfactant, N-hexadecyl ethylenediamine triacetic acid (HED3A)
製造方法
Synthesis of 1-Bromohexadecane from hexadecanol by bromination: put hexadecanol into the reaction pot and stir, heat, melt and put in red phosphorus. Add bromine drop by drop at 100℃ with sufficient stirring on one side, control 120-130℃, about 6h drop by drop, continue the reaction and drain the hydrogen bromide. Cool to below 50 ℃, add saturated and sodium chloride, stirring and washing, resting stratification, parting off the lower waste stream, then wash with water to neutral, distillation, collect 220-230 ℃ (2kPa) fraction, to obtain 1-bromohexadecane.
純化方法
Shake the bromide with H2SO4, wash with H2O, dry with K2CO3 and fractionally distil it in vacuo.[Beilstein 1 IV 542.]
