Use
Recrystallise glycine anhydride from H2O (plates) and it can be sublimed (slowly) at 260o or at 140-170o/0.5mm. The dihydrochloride has m 129-130o and is prepared by dissolving it in conc HCl and adding EtOH to crystallisation point; dry it in a vacuum. The bis-1-naphthylurethane has m 232o(dec), and the diperchlorate has m 117o (hygroscopic).
