実験手順

Uncoated Dextromethorphan Resin Complex was prepared by first dissolving 119.28 g of dextromethorphan HBr in 1 L of purified water heated to 75-80° C., followed by the addition of 223.01 g AMBERLITE IRP-69 resin under gentle mixing for 4 hours. At the completion, the suspension was allowed to settle, and was then decanted and rinsed with purified water twice and dried in an oven maintained at 50° C. until the moisture content was around 5%. The dried resin complex was hand sieved through a 40 mesh screen.
