Versuchsvorschrift

0.3 g of alpha-lactose monohydrate was dissolved in 2 ml deionized water, 98 ml of methanol was added to the aqueous solution and the mixture was introduced into the 32 ml particle formation vessel through the three-passage nozzle. The operating conditions were 270 bar and 70° C. inside the vessel, a solution flow rate (in the intermediate nozzle passage) of 0.5 ml/min and a supercritical CO2 flow rate (in the inner and outer passages) of 7.5 ml/min. The product (a fine white powder) was collected at the end of the experiment. An SEM micrograph and XRD pattern for the product are shown in FIGS. 5 and 6 respectively.
