Методы очистки

The acid has been recrystallised from H2O (fine needles) and is freely soluble in boiling H2O. It crystallises also from H2O on addition of acetone. Alternatively purify it by chromatography on Dowex 1 (in formate form), eluting with 0.25M formic acid. It is then adsorbed onto charcoal (which had been boiled for 15minutes with M HCl, washed free of chloride and dried at 100o) and recovered by stirring three times with isoamyl alcohol/H2O (1:9 v/v). The aqueous layer from the combined extracts is evaporated to dryness under reduced pressure, and the product is crystallised twice from hot H2O. [Morrison & Doherty Biochem J 79 433 1961]. It has max 259nm ( 15,400) in H2O at pH 7.0. [Alberty et al. J Biol Chem 193 425 1951, Martell & Schwarzenbach Helv Chim Acta 39 653 1956]. The acridinium salt has m 208o [Baddiley & Todd J Chem Soc 648 1947,
