| titleOfInvention | Process for improving flow characteristics of crystalline ibuprofen |
| abstract | A process for producing crystalline ibuprofen having a crystal habit characteriz ed by a particle length larger than 75 microns average and a length to width aspect ratio of greater than about 4 to 1 to about 5 to 1. The process involves crystallizing ibuprofen from a saturated solution of ibuprofen in a liquid hydrocarbon solvent by seeding and cooling such solution to a temperature of about 0 .degree.C to about -20 .degree.C at a rate to retard prim ary nucleation and promote secondary nucleation. The crystalline ibuprofen is separated from the slurry produced from such cooling. |
