• Abstract:

  In this work, supercritical fluid technology were used to prepare coumarin / dimethyl-β-cyclodextrin complexes. The products obtained were characterized by UV-vis spectroscopy , the power x-ray-diffraction and the DSC analysis, and compared with those of the physical mixture. The complex formation were confirmed by the complete disappearance ..
