Rensingsmetoder |
Purify cedrol by recrystallisation from aqueous MeOH. It is estimated colorimetrically with H3PO4 in EtOH followed by vanillin and HCl [Hayward & Seymour Anal Chem 20 572 1948]. The 3,5-dinitrobenzoyl derivative has m 92-93o. [Stork & Clarke J Am Chem Soc 83 3114 1961, Beilstein 6 III 424.] |
