Butanol (I) wird durch die Wismutverbindung (II) zu einem Gemisch aus Butyraldehyd (III), Butylacetat (IV), Benzol (V) sowie einem Gemisch verschiedener Phenylwismut‐acetate (VI) oxidiert.
Heat capacities of triphenylantimony dimethacrylate Ph3Sb(O2CCMeCH2)2 were measured by precision adiabatic vacuum calorimetry over the temperature range from T = (6 to 335) K and by differential scanning calorimetry over the temperature range from T = (300 to 470) K. The melting of the sample was observed within the above temperature range. The melting was accompanied by a compound decomposition. On the obtained data, the standard thermodynamic functions of molar heat capacity C

o(0) of Ph3Sb(O2CCMeCH2)2 were calculated over the range from T = (0 to 400) K. The low-temperature (T < 50 K) heat capacity dependence was analyzed on the basis of Debye's heat capacity theory of solids and its multifractal model, so the characteristic temperatures and the fractal dimension were determined, and some conclusions about the structure topology were made. The standard entropy of formation at T = 298.15 K of Ph3Sb(O2CCMeCH2)2(cr) was calculated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
