| Purification Methods |
Crystallise the pentaacetate from MeOH or EtOH. It is best purified by recrystallising 160g from 1L of hot 95% EtOH (charcoal) and filtering hot. It is important that as soon as the temperature of the filtrate cools to ~20o it is filtered off. Note that some -D-isomer will crystallise out if a prolonged crystallisation period is allowed. Further crystallisation in this manner and drying in a vacuum over CaCl2 will give pure -D-anomer which has m 132o, [] D 20 + 4o (c 5, CHCl3).
