  • Calculation of the Isobaric Heat Capacities of the Liquid and Solid Phase of Organic Compounds at and Around 298.15 K Based on Their “True” Molecular Volume
    molecules Article Calculation of the Isobaric Heat Capacities of the Liquid and Solid Phase of Organic Compounds at and around 298.15 K Based on Their “True” Molecular Volume Rudolf Naef Department of Chemistry, University of Basel, 4003 Basel, Switzerland; [email protected]; Tel.: +41-61-9119273 Received: 28 March 2019; Accepted: 20 April 2019; Published: 24 April 2019 Abstract: A universally applicable method for the prediction of the isobaric heat capacities of the liquid and solid phase of molecules at 298.15 K is presented, derived from their “true” volume. The molecules’ “true” volume in A3 is calculated on the basis of their geometry-optimized structure and the Van-der-Waals radii of their constituting atoms by means of a fast numerical algorithm. Good linear correlations of the “true” volume of a large number of compounds encompassing all classes and sizes with their experimental liquid and solid heat capacities over a large range have been found, although noticeably distorted by intermolecular hydrogen-bond effects. To account for these effects, the total amount of 1303 compounds with known experimental liquid heat capacities has been subdivided into three subsets consisting of 1102 hydroxy-group-free compounds, 164 monoalcohols/monoacids, and 36 polyalcohols/polyacids. The standard deviations for Cp(liq,298) were 20.7 J/mol/K for the OH-free compunds, 22.91 J/mol/K for the monoalcohols/monoacids and 16.03 J/mol/K for the polyols/polyacids. Analogously, 797 compounds with known solid heat capacities have been separated into a subset of 555 OH-free compounds, 123 monoalcohols/monoacids and 119 polyols/polyacids.

The Bureau's overall goal is to strengthen and advance the Nation’s science and technology and facilitate their effective application for public benefit. To this end, the Bureau conducts research and provides: (1) a basis for the Nation’s physical measurement system, (2) scientific and technological services for industry and government, (3) a technical basis for equity in trade, and (4) technical services to promote public safety. The Bureau consists of the Institute for Basic Standards, the Institute for Materials Research, the Institute for Applied Technology, the Institute for Computer Sciences and Technology, and the Office for Information Programs. THE INSTITUTE FOR BASIC STANDARDS provides the central basis within the United States of a complete and consistent system of physical measurement; coordinates that system with measurement systems of other nations; and furnishes essential services leading to accurate and uniform physical measurements throughout the Nation’s scientific community, industry, and commerce. The Institute consists of the Office of Measurement Services, the Office of Radiation Measurement and the following Center and divisions: Applied Mathematics — Electricity — Mechanics — Heat — Optical Physics — Center for Radiation Research: Nuclear Sciences; Applied Radiation — Laboratory Astrophysics 2 2 2 2 — Cryogenics — Electromagnetics — Time and Frequency .

  • Investigation of the Atmospheric Ozone Formation Potential of Methyl Pivalate
    INVESTIGATION OF THE ATMOSPHERIC OZONE FORMATION POTENTIAL OF METHYL PIVALATE Report to ExxonMobil Chemical Company by William P. L. Carter, Dongmin Luo, and Irina L. Malkina November 17, 2000 College of Engineering Center for Environmental Research and Technology University of California Riverside, California 92521 00-AP-RT2R-001-FR ABSTRACT A series of environmental chamber experiments and computer model calculations were carried out to assess the atmospheric ozone formation potentials of methyl pivalate. The experiments consisted of determining the effects of this compound on NO oxidation, ozone formation, OH radical levels, and other measures of reactivity when added to varying simulated model photochemical smog systems. Methyl pivalate was found to slightly enhance O3 formation under conditions most representative of the atmosphere, but to inhibit radical levels and inhibit O3 in experiments that are sensitive to effects on radical levels. A mechanism for the atmospheric reaction for methyl pivalate was developed that is consistent with available laboratory data and current estimation methods, and that could simulate the results of these experiments after only minor adjustments of the overall nitrate yield to within its range of uncertainty. This mechanism was then incorporated in the overall SAPRC-99 mechanism and used to predict the atmospheric ozone impacts of this compound under various atmospheric conditions. The ozone formation potentials of methyl pivalate on a mass basis was found to be about 10-20% that of the mixture used to represent reactive VOC emissions from all sources. Its ozone formation potentials were found to be very similar to those of ethane, the compound used by the EPA as the basis for determining exemptions of compounds from regulation as ozone precursors.
