실험 절차

A sample of 149.4 g of hydrocodone bitartrate containing 2.1 wt % of ethanol was placed in a crystallisation dish. The sample was placed in a vacuum oven along with a crystallisation dish containing water (ca 200 ml). A vacuum was applied (16665 pascals (approximately 10 mm to 1 mm Hg)) and the sample was dried at 60° C. for 24 hours to afford 151.7 g of ethanol-free (as defined below) product. The water content measured by Karl Fisher titration was 9.66% which indicated that the final product was a hemi-pentahydrate.
