Definitions

  • the present invention relates to a process for the crystallisation of a chemical substance, and more particularly a substance to be used as a pharmaceutically active agent.
  • Crystallisation is a well known technique for the purification of chemical compounds. Crystalline products prepared using traditional batch methodology may vary; for example in the degree of agglomeration experienced and the habit and size of individual crystals so formed. Moreover, in some circumstances, conventional batch mode crystallisation may give poor results, i.e. produces oils or crystals containing occluded impurities. There is therefore a need for a crystallisation process that gives rise to products of uniform and consistently small crystal size without the problems of batch processing, especially oiling or solvent inclusion. This is particularly true for pharmaceutically active compounds which might otherwise have to be milled to improve their bio-availability, or to increase their suitability in processing, e.g. the electrostatic deposition of active ingredients in tablet manufacture.
  • a process for the continuous crystallisation of an organic chemical compound which comprises contacting a stream of either the compound or a salt thereof dissolved in a solvent with a stream of anti-solvent or colder solvent, or a solution of an appropriate acid or base, and separating off the crystals formed.
  • the solute/solvent/antisolvent system will be one which has a fast precipitation time, as this gives rise to particularly small crystals.
  • 'precipitation time' we mean the time taken to observe precipitation in a mixed system e.g. cloudiness.
  • Precipitation times can be determined by mixing and observing precipitation in individual solvent systems.
  • the precipitation time will be less than 1 minute, especially less than 5 seconds, and particularly less than 1 second.
  • Precipitation times may be varied by adjusting the concentration of solute, the rates of flow of solution and anti-solvent, and the temperatures of the solvent and anti-solvent. It should be recognised that the process of crystallisation can involve the initial formation of amorphous solid particles which rapidly change into a crystalline form.
  • the contacting process may prove satisfactory for the contacting process to be undertaken using a simple three-way pipe connection (for example a T or ⁇ - connection) provided that appropriate flow rates are used.
  • a simple three-way pipe connection for example a T or ⁇ - connection
  • the contacting process is undertaken using conditions of high shear and turbulence.
  • Mixing devices suitable for use in this invention include known in-line mixers, e.g. of the type in which one or more turbulence-creating elements are located within a pipeline through which the components are caused to flow.
  • Another suitable type of mixer is a homogeniser, e.g. of the type in which two liquid phases are forced under pressure through a biased valve.
  • Suitable mixing devices may also include cavities subjected to high turbulence and or shear stress by means of turbines, propellers etc.
  • mixers for creating conditions of high shear and turbulence are a chamber wherein introduced fluids are subjected to intense rotational swirling, for example a vortex chamber of the type disclosed generally in EP-
  • the vortex chamber comprises a chamber of substantially circular cross section, e.g. generally cylindrical in shape, and having tangential inlets and an axial outlet.
  • the components are introduced via the tangential inlets where they experience swirling and intense mixing as they radially accelerate towards the centrally located outlet.
  • a vortex mixer e.g. a Power Fluidics mixer
  • the mixing is carried out under controlled residence times in the mixer as this gives rise to a product of uniform crystal size. Fast precipitation times give rise to particularly small crystals.
  • Each stream is fed at high velocity into the central mixing chamber where it is mixed and accelerated towards to the central exit orifice.
  • the internal diameter of such a vortex chamber is about 8 mm, and its height about 1mm.
  • a combination of small mixing chamber volume (approx. 0.05-0. lml) and high throughputs preferably between 0.5L and 2L/min) generate typical residence times of less than 10ms in a steady-state environment where all elements of the mixed stream experience
  • the mixed stream of solute in solvent and anti-solvent is cooled during the mixing process and/or subsequent to it before the crystalline material is separated from the solvent stream.
  • the outlet flow from the mixer e.g. the Power Fluidic mixer
  • the tubular reactors e.g. a flexible tubular reactor
  • such tubular reactors are cooled.
  • the compound to be crystallised is an active ingredient for a pharmaceutical composition.
  • Particularly preferred compounds for crystallisation in accordance with the process of this invention are: Eprosartan methanesulphonate - (-(E)-(-[[2-butyl-l-[(4-carboxyphenyl)methyl]-lH- imidazol-5-yl]methylene]-2-thiophenepropanoic acid methanesulphonate); and Nabumetone - 4-(6-methoxy-2-naphthalenyl)-2-butanone.
  • the process is one in which the compound to be crystallised is the same as the compound dissolved in the solvent prior to addition of the anti-solvent (e.g. neutral molecule, free acid or base, acid-addition salt or base-addition salt).
  • the process can also be used where a solution containing the free acid or base of a compound is mixed under conditions of high turbulence with a solvent containing either acid or base to form a salt, or alternatively where a solution of a salt of a compound is rapidly mixed under conditions of high turbulence with a solvent containing an acid or base.
