Embodiment 1
[0031] Example 1: Preparation of Erdosteine Crystals
[0032] (1) Take erdosteine raw material, add it into deionized water at 50°C, and the volume of deionized water is 5 times the mass of erdosteine;
[0033] (2) Stir until completely dissolved;
[0034] (3) Add activated carbon for decolorization and filter to obtain a clear solution;
[0035] (4) Move the clarified solution into a pressure vessel, add isopropanol dropwise at 5°C under the condition of controlling the pressure in the pressure vessel at 1.0Mpa and stirring, the stirring speed is 35rmp, and the volume of isopropanol is deionized 5 times the volume of water;
[0036] (5) Release the pressure after the dropwise addition, cool the solution to -5°C at a rate of 10°C / min, let it stand for 2 hours, filter, wash, and dry under reduced pressure to obtain erdosteine crystals.
[0037] The X-ray powder diffraction pattern obtained by measuring the obtained erdosteine crystal using Cu-Kα ray is as follows: ...
