Thermodynamic properties of heptacyclotetradecane C14H16

Thermodynamic properties of methyl esters of benzoic and toluic acids in the condensed state

“…and the mole-fraction purities x determined by the fractional-melting method for the samples used in the study described. (4)(5)(6)(7) The liquid samples of masses 1.03013 g for methyl benzoate, 0.61200 g for methyl o-toluate, 0.61162 g for methyl m-toluate, and 1.03417 g for methyl p-toluate were loaded into stainless-steel containers, which were filled with a heat-exchange helium gas. Containers were sealed with an indium gasket.…”

Thermodynamic properties of some cyclohexyl esters in the condensed state

“…(3)(4)(5)(6) The liquid samples with masses of 0.90825 g for CHF, 0.51808 g for CHA, 0.88950 g for CHB, and 0.56140 g for CHV were loaded into stainless-steel containers, which were filled with helium gas for heat-exchange. Container sealing was made with an indium gasket.…”

Thermodynamic properties of pentacyclo[5.4.0.02,6.03,10.05,9]undecane, C11H14

“…A more detailed description of the calorimeter appears in an earlier publication. (1) The molar heat capacities C sat, m of samples at Tq300 K and the molar enthalpy of fusion D fus H°m were measured by the triple heat-bridge method, which is described in detail elsewhere. (3) The error of the C sat, m measurements, as established by using reference compounds, did not exceed 1.5·10 −2 ·C sat, m to 2·10 −2 ·C sat, m .…”

“…(19) A detailed description of the apparatus has appeared in an earlier publication. (1) An isoperibol calorimeter equipped with a static bomb and an isothermal water jacket was used for measurements of the energy of combustion. The internal volume of the bomb was 320.5 cm 3 .…”

“…( 1) It was shown that additional strain energy which results via formation of a cage structure from the fusion of five-membered cycles is probably much less than the sum of the strain energies of the independent rings. The substance B possesses an extremely high density: r(293 K)=1.242 g·cm −3 , in comparison with other crystalline hydrocarbons.…”
