Patent number: 8846954Abstract: A method for the production of crystalline glycopyrronium bromide, comprises the reaction of glycopyrronium base with methyl bromide in a solvent, in which the solvent is selected such that the diastereoisomeric ratio of the product favors the R,S and S,R diastereoisomers over the R,R, and S,S diastereoisomers, and separating the desired diastereoisomers by one or more controlled crystallization steps. This method gives a product having a particle size of narrow distribution.Type: GrantFiled: March 3, 2006Date of Patent: September 30, 2014Assignee: Sosei R&D Ltd.Inventors: Andrew Douglas Baxter, Kenneth Walter Sinden, Stefan Kleinebekel

Patent number: 8210403Abstract: A method for the vaporization of particulate material (10) includes providing one or more containers (15) each containing possibly distinct particulate materials (10) each having at least one component, fluidizing the particulate material (10) in at least one of the containers (15), and providing a vaporization zone (50) that is thermally isolated from at least one of the containers (15). The method further includes delivering particulate material received from each container (15) to the vaporization zone (50), and applying heat to vaporize the delivered particulate materials (10) at the vaporization zone (50).Type: GrantFiled: March 13, 2006Date of Patent: July 3, 2012Assignee: Sosei R&D Ltd.Inventors: Sergio Malorni, David John Marchant
