| titleOfInvention | A kind of (R)-lansoprazole anhydrous crystal forms and preparation method thereof |
| abstract | The invention discloses one (R)-lansoprazole anhydrous crystal forms and preparation method thereof.This anhydrous crystal forms is Cu-K α at use source of radiationn 1 powder x-ray diffraction spectrum in, in diffraction angle 2 θ=7.66,11.23,13.18,13.68,15.28,15.58,17.44,18.43,18.64,20.19,21.10,21.84,22.70,22.88,23.23,24.20,25.45,26.26,27.04,27.46,28.81,30.20,30.56,30.97,31.32,31.62,32.61, there is peak at 33.48,34.42,36.36,37.38,37.92 and 39.35 degree of places; 2 θ value limit of error are ± 0.3.This preparation method comprises the steps: in a heated condition, (R)-lansoprazole is dissolved in organic solvent, adds diethylamine and mix, under the condition of 30 ~ 45 DEG C, add anti-solvent afterwards to point covered with clouds, then cooling crystallization, separating obtained crystal.This anhydrous crystal forms physico-chemical property is excellent, stability is high. |
