The heat capacity of triphenylantimony diacrylate Ph 3 Sb(O 2 CCH=CH 2 ) 2 was studied in an adi abatic vacuum calorimeter at 6-350 K and differential scanning calorimeter at 330-450 K. Melting was revealed at these temperatures; the melting point was estimated at 428.4 ± 0.5 K. It was accompanied by the partial decomposition of the substance. The low temperature (20 K ≤ T ≤ 50 K) heat capacity was treated using the Debye theory of the heat capacity of solids and its multifractal model. The type of the structure topology was determined. The standard thermodynamic functions (T), H°(T) -H°(0), S°(T), and G°(T) -H°(0) of the compound in the crystal state were calculated from the obtained experimental data in the range from T → 0 to 428 K. The standard entropy of the formation of the crystalline compound Ph 3 Sb(O 2 CCH=CH 2 ) 2 at T = 298.15 K was determined.
scite is a Brooklyn-based startup 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 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.
