真空干燥脱水就可以吧

下一步如果溶剂含水，不要干燥了。

这东西好多都用在油水反应体系里了，目的就是均相，加的时候就是加个表面活性剂用量的范围，我用的时候就很少称量

有心人帮帮忙啊，哪位朋友做过？

就看它参与的反应里有没有水了，要有，就真的无所谓了

若是要求无水条件又该怎么处理呢？怎样才能成功的干燥？

60度，40mmHg下真空干燥36~48hr
Tetra-n-butylammonium bromide [1643-19-2] M 322.4, m 1 1 9 . 6o. Crystallise the salt from *benzene (5mL/g) at 80o by adding hot n-hexane (three volumes) and allowing to cool. Dry it over P2O5 or Mg(ClO4)2, under vacuum. The salt is very hygroscopic. It can also be crystallised from ethyl acetate or dry acetone by adding diethyl ether and dried in vacuo at 60℃ for 2 days. It has been crystallised from acetone by addition of diethyl ether. It is so hygroscopic that all manipulations should be carried out in a dry-box. It has been purified by precipitation from a saturated solution in dry CCl4 on addition of cyclohexane or by recrystallisation from ethyl acetate, then heating in vacuum to 75o in the presence of P2O5. [Symons et al. J Chem Soc, Faraday Trans 1 76 2251 1908.] It also recrystallises from CH2Cl2/diethyl ether and is dried in a vacuum desiccator over P2O5.
