Ibuprofen (IB), a nonsteroidal anti-inflammatory drug, is a chiral molecule and is currently used clinically as a racemate (racIB). Usually, conventional solvents are employed for the separation and recovery of ibuprofen. Breakage affects the extraction performance and hence is an important parameter. The bulk volume of the porous mass was noted in terms of expansion ratio. The skeletal formula of 2-methylpropylbenzene is shown on the right. We conducted an XRD study using Cu radiation filtered by Ni to characterize the physical form of ibuprofen in selected sample formulations.
