“…The provenance of the ATcT enthalpy of formation of methanol is quite distributed, the top 90% being spread over 168 determinations, with 965 determinations needed to pedigree 99%. The provenance is somewhat top-heavy, with the combustion calorimetry of gas-phase methanol by Rossini − emerging as the most prominent contributor (49.4%). Other experimental contributors include the combustion calorimetry of hydrogen ,, (2.4%) and of liquid methanol (1.9%), photoionization measurements of AE 0 of CH 2 OH + from methanol by Borkar et al .…”

Active Thermochemical Tables (ATcT) thermochemistry for the sequential bond dissociations of methane, ethane, and methanol systems were obtained by analyzing and solving a very large thermochemical network (TN). Values for all possible C-H, C-C, C-O, and O-H bond dissociation enthalpies at 298.15 K (BDE298) and bond dissociation energies at 0 K (D0) are presented. The corresponding ATcT standard gas-phase enthalpies of formation of the resulting CHn, n = 4-0 species (methane, methyl, methylene, methylidyne, and carbon atom), C2Hn, n = 6-0 species (ethane, ethyl, ethylene, ethylidene, vinyl, ethylidyne, acetylene, vinylidene, ethynyl, and ethynylene), and COHn, n = 4-0 species (methanol, hydroxymethyl, methoxy, formaldehyde, hydroxymethylene, formyl, isoformyl, and carbon monoxide) are also presented. The ATcT thermochemistry of carbon dioxide, water, hydroxyl, and carbon, oxygen, and hydrogen atoms is also included, together with the sequential BDEs of CO2 and H2O. The provenances of the ATcT enthalpies of formation, which are quite distributed and involve a large number of relevant determinations, are analyzed by variance decomposition and discussed in terms of principal contributions. The underlying reasons for periodic appearances of remarkably low and/or unusually high BDEs, alternating along the dissociation sequences, are analyzed and quantitatively rationalized. The present ATcT results are the most accurate thermochemical values currently available for these species.

The existing thermochemical data on the normal olefin (al kene-I) hydrocarbons are reviewed and conelated. These data are used in conjunction with the value previously proposea for the increase in the heat content per added CH2 group to obtain values for those members of this series of hydrocarbons for which no calorimetric data exist. For all these hydrocarbons in the gaseous state, selected "best" values are given for the h eats of combustion at 25°C and for the heats of formation, from solid carbon and gaseous hydrogen , at 25°C and OOK.As in the case of the previously reported values for the normal paraffin hydrocarbons and primary normal alkyl alcohols, the h eats of formation of the gaseous normal olefin (alkene-I ) hydrocarbons can he r epresented by means of an expression of the form t::.H = A+ Bn+t::., where t::.1-1 is the heat of formation, A and B are constant for a given temperature, n is the num be r of carbon atoms in the molecule Cn H2n, and t::. is the t erm giving the deviation from linearity, which is zero for n> 5. Values of the constants A and B and of t::. are given both for 25° C and 0° K.
