| titleOfInvention | Multistage feeding formula anti-solvent jet crystallization device and its jet crystallization method |
| abstract | The present invention is a kind of multistage feeding formula anti-solvent jet crystallization device and its jet crystallization method, the tube type mold that the crystallizer is vertically arranged, supervisor entrance (1) is equipped on the top of the tube type mold, symmetrical aperture or slit (2) are provided with along the different height position of supervisor's wall from top to bottom, surge chamber (3) are provided with around the aperture or slit (2) of identical height and position, each surge chamber is provided with side feed inlet (4), is equipped with supervisor outlet (5) in the lower part of the tube type mold.The particle P of heterocyclic organic drug particle, inorganic salts or oxide, nitro class energetic material is dissolved in good solvent S and is configured to certain density solution system A, crude product particle P is recrystallized using tube type mold, solution system A and poor solvent quickly mix, nucleus and continued growth are constantly formed, finally obtains the suspension containing fine grained P in the outlet of jet crystallization device.Have many advantages, such as particle size by the grain products that this method obtains and distribution is controllable, particle diameter distribution is narrow. |
