4. The non-solvated crystalline darunavir according to claim 3 , further characterized by a DSC thermogram as depicted in FIG. 2 .

5. A process for the preparation of non-solvated crystalline Darunavir comprising the steps of:

a) dissolving Darunavir in an ester solvent,

b) adding an anti solvent, and

c) isolating non-solvated crystalline Darunavir.

6. The process according to claim 5 , wherein the solvent is selected from ethyl acetate, methyl acetate or butyl acetate and anti solvent is selected from hexane, heptane or cyclohexane.

7. A process for the preparation of amorphous Darunavir comprising the steps of:

a) dissolving non-solvated crystalline Darunavir in a solvent,
