Zusammenfassung:The invention belongs to the field of chemical and pharmaceutical engineering, and relates to a darunavir crystal form and a preparation method thereof. A powder X-ray diffraction spectrum of the darunavir crystal form has characteristic peaks when a reflection angle 2theta is 7.50+/-0.2, 8.62+/-0.2, 12.17+/-0.2, 13.64+/-0.2, 15.65+/-0.2 and 18.16+/-0.2, and an infrared spectrum has characteristic peaks at 1693cm, 3348cm and 3465 locations. Meanwhile, the invention also provides the preparation method of the crystal form.
