Editor: Gupta, R.R.; Lechner, M.D. Source: Landolt-Börnstein, New Series Volume: III/35D2 Year: 2005 Keyword: aromatic compounds; carbon-13; chemical shift; coupling constant; molecular structure ISBN: 978-3-540-20189-2 ISBN: 3-540-20189-0 Internet Resource: DOI:10.1007/b83345 RefComment: VIII, 291 p., Hardcover RefComment: Written for Science and engineers in the fields of physics, chemistry and physical chemistry who inted to use NMR to study the structure and the binding of molecules Abstract: Nuclear Magnetic Resonance (NMR) is based on the fact that certain nuclei exhibit a magnetic moment, orient by a magnetic field, and absorb characteristic frequencies in the radiofrequency part of the spectrum. The spectral lines of the nuclei are highly influenced by the chemical environment i.e. the structure and interaction of the molecules. NMR is now the leading technique and a powerful tool for the investigation of the structure and interaction of molecules. The present Landolt-Börnstein volume III/35 Nuclear Magnetic Resonance (NMR) Data is therefore of major interest to all scientists and engineers who intend to use NMR to study the structure and the binding of molecules. Volume III/35 "NMR-Data" is divided into several subvolumes and parts. Subvolume III/35A contains the nuclei 11B and 31P, subvolume III/35B contains the nuclei 19F and 15N, subvolume III/35C contains the nucleus 1H, subvolume III/35D contains the nucleus 13C, subvolume III/35E contains the nucleus 17O, and subvolume III/35G contains the nucleus 77Se. More nuclei will be presented later.

- 方法一:1.三氟甲基苯直接溴化法该方法收率为80%。原料消耗定额:三氟甲基苯(≥98%)686kg/t、溴素1142kg/t、铁粉200kg/t。2.由间氨基三氟甲苯重氮化、置换而得。搅拌下将间氨基三氟甲苯慢慢加入氢溴酸中,温度不超过50℃。冷却,加入亚硝酸钠溶液,温度控制在10℃以下,至重氮化结束。将重氮液加入煮沸的溴化亚铜和氢溴酸溶液内,并开始水蒸气蒸馏,将有机物随水蒸气蒸出。馏出液分层,取有机层,加浓硫酸洗涤,再用水、稀碱液洗涤,水洗涤至中性。油层用无水氯化钙脱水,过滤,减压蒸馏,收集73-74.5℃(6.0kPa)馏分,得间溴三氟甲苯。
