Versuchsvorschrift

In a 150 mL glass beaker, 100 gram of 20% w/w citric acid solution was prepared and 2.2 gram of carvedilol was added. The solution became slightly brownish after 15 minutes stirring, with only a little solid sticking on the bottom of the beaker. The beaker was then placed in a fume hood for evaporation. After staying in the hood overnight, large single crystals appeared in the beaker. The solid crystals were isolated and dried in a desiccator under vacuum. Similarly single crystals of citrate salt could be obtained by slow evaporation of carvedilol/citric acid solutions (containing citric acid 5%, 10% or 20% w/w) in Petri dishes (150 mm diameter) placed in a desiccator connected to a house vacuum.
