| Use | bromodecane was used to prepare soluble carbon nanoonions by covalent functionalization with a decanoyl chain. It can also be used in the synthesis of [2-(methacryloyloxy) ethyl] dimethyldecanoylammonium bromide monomer for the synthesis of novel methacrylate-based adsorbents. for the production of surfactants, also used in the system of fungicides, detergents and so on. Surfactant intermediates, also used in fungicides; Detergent production. |
| production method | the product is obtained by bromination of decaethol: the decaethol is stirred in a reaction pot, heated and melted, and red phosphorus is added. At 100 ° C., bromine was added dropwise while fully stirring, and controlled at 120-130 ° C. After about 6 hours, the dropwise addition was completed, and the reaction was continued and the hydrogen bromide was exhausted. Cool to below 50 ℃, add saturated and sodium chloride, stir and wash, stand and separate into layers, remove the lower waste liquid, then wash with water until neutral, distill, collect 220-230 ℃(2kPa) fraction, 1-bromodecane was obtained. |
