Enthalpies of formation of M(η-C5H5)2L complexes (M = Mo, W, Ti; L = C6H4O2, C10H6O2, C14H8O2)

Enthalpies of formation of crystalline dimethyldithiocarbamate complexes of chromium(III) and iron(III): the estimation of the mean M–S bond-dissociation enthalpies

“…was used as supplied. A glass Dewar calorimeter containing 120 cm 3 of solvent, previously described, (14) was used. The samples were sealed in thin glass ampoules that were broken into the appropriate solvent by compression between two glass rings.…”

Theoretical Study on the Thermodynamic Properties and Self-Decomposition of Methylbenzenediol Isomers

“…Table gives the calculated enthalpies of formation (Δ f H 298 ° ). The experimental standard enthalpies of formation for methylbenzenediol isomers listed in this table range from −69.69 ± 1.0 to −71.32 ± 0.79 kcal/mol. , The values calculated from differ from their corresponding experimental ones by 1.82−2.60 kcal/mol. Taking into account the marginal error in the theoretical method, along with the uncertainty in the enthalpy of formation of the reference species, the calculated and experimental enthalpies based on can be considered to be in satisfactory agreement.…”

Standard molar enthalpies of formation ofNi(CH3COO)2,Ni(CH3COO)2·4.00 H2O,Cd(CH3COO)2, andCd(CH3COO)2·2.00 H2Oin the crystalline state

“…The calorimetric solvents, HCl (aq, c = 1.000 mol · dm −3 ), H 2 SO 4 (aq, c = 0.500 mol · dm −3 ) and CH 3 COOH (aq, c = 2.000 mol · dm −3 ) were obtained by dilution with deionized water of Merck Titrisol ampoules of the acids: the compositions were, (2) respectively, HCl · 54.36H 2 All the compounds were studied in a Dewar isoperibol solution-reaction calorimeter (3,4) with a newly designed all-glass reaction vessel (5) equipped with a twin-bladed stirrer and with an ampoule holder that allows the introduction of new ampoules into the reaction vessel without having to take the reaction vessel out of the thermostatic bath. The calorimeter temperatures were measured using a quartz crystal thermometer (Hewlett Packard HP 2804-A) to 10 −4 K, every 10 s. The calorimetric system was interfaced to a PC using the program LABTERMO (5) to control the system.…”
