Patent number: 7404828Abstract: A method of preparing particles of a substance, for example selected from a flavor, fragrance, pigment, dye, biologically active compound or a plastics material, comprises contacting the substance of a formulation (which may include the substance in conjunction with a second solvent) with a first solvent which comprises a C1-C4 hydrofluorocarbon, especially tetrafluoroethane, and subjecting the resultant mixture to a separation process, for example, by allowing the mixture to be sprayed as a mist (14) from a high pressure environment in a first vessel (2) to a low pressure environment in a second vessel (8), thereby to cause separation of a least some of the substance from the first solvent and the formation of fine particles (20) of the substance.Type: GrantFiled: November 15, 2000Date of Patent: July 29, 2008Assignee: Glaxo Group LimitedInventor: Mazin Nicola

Publication number: 20060084812Abstract: An improved process for improving the purity of an impure material, for example for producing low color nicotine is disclosed. The process involves passing a solution of less pure material, for example nicotine, in a non-aqueous solvent, such as a fluorinated hydrocarbon, for example tetrafluoroethane, through an ion exchange resin or absorbent such that the impurity is retained on the resin, and purer material passes through. The process eliminates the need for distillation to prepare a purer material, for example to separate nicotine from colour causing compounds. Said process is non-flammable, non-ozone depleting, and has low toxicity.Type: ApplicationFiled: January 18, 2002Publication date: April 20, 2006Inventors: Simon Bellamy, Lyn Hughes, Mazin Nicola

Patent number: 6383772Abstract: A first compound is converted to a second compound enzymatically in a solvent mixture containing water and a fluorinated, non-chlorinated alkane, alkene, or alkyne having up to 4 carbon atoms. Lactams, for example 6-aminopenicillanic acid (6-APA), may be prepared by enzymatic conversion of a first compound, for example penicillin-G, in a solvent mixture comprising water and a non-aqueous organic solvent, for example 1,1,1, 2-tetrafluoroethane. The 6-APA can be caused to precipitate, isolated by filtration and optionally derivatized to produce a desired compound. A by-product of the enzymatic conversion, for example phenylacetic acid, can be isolated by solvent extraction, suitably using a solvent which also comprises 1, 1, 1, 2-tetrafluoroethane.Type: GrantFiled: March 2, 2000Date of Patent: May 7, 2002Assignee: Advanced Phytonic LimitedInventor: Mazin Nicola
