실험 절차
Codeine base (4.0002 g; 12.60 mmol) was dissolved in ethanol (100 mL; 99.7-100%) with stirring. Lauric acid (2.7822 g; 13.86 mmol; 10% excess relative to codeine base) was dissolved in the ethanol/codeine solution. The resulting solution was stirred for 5 minutes. The ethanol was removed by rotary-evaporation to give a pale yellow residue. The residue was redispersed in ethyl acetate (10 mL) by heating on a water bath (60° C.). Once all the material had redissolved the solution was placed at 4° C. for 16 hours. A white precipitate formed which was isolated by vacuum filtration. The precipitate was dried further in a vacuum oven for 16 hours at 40° C. to give codeine laurate (2.4757 g; 36.50%). The material was analysed by Differential Scanning Calorimetry in order to determine the melting point. However, thermal analysis from 50 to 200° C. showed no thermal event.
