Thermodynamic characteristics of triphenylantimony diacrylate

Abstract

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.

Bis(but-2-enoato-κO)triphenylbismuth(V)

“…Organic glasses based on triphenylantimony diacrylate and methylmethacrylate having increased fungal resistance are now available (Dodonov et al, 2004). The thermodynamic properties of triphenylantimony diacylates have been studied (Letyanina et al, 2012;Markin et al, 2011). The crystal structure and chemistry of a similar orgaonmetallic compound of antimony has been reported by Gushchin et al (2013).…”

Calorimetric study of organic compounds of antimony and bismuth Ph3Sb(O2CCH=CHCH3)2 and Ph3Bi(O2CCH=CHCH3)2

“…Previously, we reported the thermodynamic properties of pentaphenylantimony Ph 5 Sb [11], tetraphenylantimony benzophenoneoxymate Ph 4 SbONCPh 2 [12], tetraphenylantimony acetophenoneoxymate Ph 4 SbONCPhMe [13], triphenylantimony diacrylate Ph 3 Sb(O 2 CCH=CH 2 ) 2 [14], triphenylantimony dimethacrylate Ph 3 Sb(O 2 CCMe=CH 2 ) 2 [15], triphenylantimony bis(acetophenoneoxymate) Ph 3 Sb(ONCPhMe) 2 [16,17], and triphenylantimony bis(1-adamantanecarboxylate) Ph 3 Sb[OC(O)C 10 H 15 ] 2 [18]. The present article continues our studies in the same line and reports the calorimetric study of the temperature dependence of the heat capacity of triphenylantimony and triphenylbismuth dicrotonates from 6.5 to 490 K including the detection of possible physical transitions, the calculation of the standard thermodynamic functions, namely C o p , H°(T)-H°(0), S°(T), and G°(T)-H°(0) from T ?…”
