Thermodynamic characteristics of triphenylantimony bis(acetophenoneoximate)

Thermodynamic characteristics of triphenylantimony diacrylate

“…Figure 3 shows a fragment of a one dimensional chain of Ph 3 Sb(O 2 CCH=CH 2 ) 2 molecules observed in crys tals. The organic derivatives of pentavalent antimony studied earlier [5][6][7][8][9] also have a chain layered struc ture topology.…”

“…Corundum was used as a reference sample. The procedure for deter mining from differential scanning calorimetry (DSC) data is described in detail in [8,16] and Netzsch Software Proteus.…”

“…The thermodynamic charac teristics of the organic derivatives of pentavalent anti mony were not sufficiently studied [4]. We examined the standard thermodynamic properties of pentaphe nylantimony Ph 5 Sb [5], tetraphenylantimony ben zophenone oximate Ph 4 SbONCPh 2 [6], tetrapheny lantimony acetophenone oximate Ph 4 SbONCPhMe [7], triphenylantimony bis(acetophenone oximate) Ph 3 Sb(ONCPhMe) 2 [8], and triphenylantimony dimethacrylate Ph 3 Sb(O 2 CCMe=CH 2 ) 2 [9], at tem peratures from 0 to 350-450 K.…”

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 ?…”

Calorimetric Study of Triphenylbismuth Dimethacrylate Ph3Bi(O2CCMe═CH2)2

“…The physicochemical investigation of these types of compounds is an actual task. Previously, we focused on the thermodynamic properties of the organic derivatives of pentavalent antimony (pentaphenylantimony Ph 5 Sb, tetraphenylantimony benzophenoneoxymate Ph 4 SbONCPh 2 , tetraphenylantimony acetophenoneoxymate Ph 4 SbONCPhMe, triphenylantimony bis (acetophenoneoxymate) Ph 3 Sb­(ONCPhMe) 2 , , triphenylantimony diacrylate Ph 3 Sb­(O 2 CCHCH 2 ) 2 , triphenylantimony dimethacrylate Ph 3 Sb­(O 2 CCMeCH 2 ) 2 , and triphenylantimony bis (1-adamantanecarboxylate) Ph 3 Sb­[OC­(O)­C 10 H 15 ] 2 ). The present paper is devoted to the calorimetric study of triphenylbismuth dimethacrylate Ph 3 Bi­(O 2 CCMeCH 2 ) 2 over the temperature range from T = 5.3 to 420 K, detection of possible physical transitions, the calculation of the standard thermodynamic functions, namely, C p,m o , H m o ( T ) – H m o (0), S m o ( T ), and Φ m o ( T ) from T → 0 to 385 K, and the standard entropy of formation, Δ f S m o at T = 298.15 K for crystalline Ph 3 Bi­(O 2 CCMeCH 2 ) 2 .…”
