Tetrapropylammonium Bromide(TPABR) CAS 1941-30-6

Tetrapropyl ammonium bromide Cas:1941-30-6, with a molecular formula of C12H28NBr and a molecular weight of 266.26; Content 99%, off white solid, melting point 266-270 ℃. Easy to absorb moisture, soluble in water and alcohol, slightly soluble in ethyl acetate. Tetrapropyl ammonium bromide Cas:1941-30-6 can be used as a molecular sieve template. And phase transfer catalysts used in organic synthesis chemistry such as halogen substitution reactions, oxidation-reduction reactions, N-alkylation, dichlorocarbene reactions, etc. A method for extracting tetrapropylammonium bromide from zeolite synthesis waste liquid: acidify the zeolite synthesis waste liquid, then add organic modified zeolite with a mass concentration of 1020g/L and attapulgite, and stir and adsorb at 6070 ℃ for 23 hours, with a stirring speed of 100200r/min. After settling for 610 hours, heat and reflux the supernatant for 1020 hours The present invention first acidifies the waste liquid, then uses attapulgite and organic modified zeolite for primary adsorption and precipitation treatment, followed by secondary reflux treatment, which can greatly improve the extraction efficiency of tetrapropyl ammonium bromide. Finally, ethyl acetate can greatly purify the extraction efficiency of tetrapropyl ammonium bromide(TPABR) CAS:1941-30-6.
