BaF(<i>p</i>-BDC)<sub>0.5</sub> as the Catalyst Precursor for the Catalytic Dehydrochlorination of 1-Chloro-1,1-Difluoroethane to Vinylidene Fluoride
A BaF(<i>p</i>-BDC)<sub>0.5</sub> catalyst was prepared by solid state reaction at room temperature with Ba(OH)<sub>2</sub> as precursor, NH<sub>4</sub>F as F source, and H<sub>2</sub>(<i>p</i>-BDC) as organic ligand. The calcin...
