Purification Methods |
Purify the tetrazole by recrystallisation from EtOH or CHCl3 (m 152o) [Tautomerism: Kauer & Sheppard J Org Chem 32 3580 1967, UV: Leiber et al. Can J Chem 37 563 1959]. The ammonium salt crystallises from EtOH and decomposes at 176o. The sodium salt crystallises from EtOH/*C6H6, melts at 96o and decomposes at 145o [Stollé J Prakt Chem [2] 133 60 1932]. It is used for the determination of Bi and Pd. [Fresenius Z Anal Chem 261 151 1972, Beilstein 26 III/IV 2065.] |
