Использование
1-Bromotetradecane was used in the synthesis of tetradecylferrocene, cationic and zwitterionic gemini surfactants, and 9-tetradecylcarbazole. Also used for synthesis of metallomesogenic polymers based on bis[η1(N)-3,4-dialkyloxybenzylidene-4?-dodecyloxyaniline]dichloropalladium(II) with octyl, decyl, dodecyl, tetradecyl and hexadecyl alkyl groups.
Подготовка
1-Bromotetradecane is synthesized from 1-tetradecanol by bromination. The 1-tetradecanol was added to the reaction pot, and the sulfuric acid was added dropwise with stirring, and the stirring was continued for half an hour after the addition. Then add hydrobromic acid, heat to 99-101°C, and react for 8h. Cool to 30°C, stop stirring, stand for 12 hours, and separate the upper layer of oil, and adjust the pH to 8 with 10% sodium carbonate solution. The water layer was separated, the oily substance was washed twice with an equal volume of 50% ethanol, the washed oily substance was added with sodium carbonate, stirred intermittently, and dried for 24h. Filtration to obtain 1-bromotetradecane.
