Journal of Applied Solution Chemistry and Modeling https://www.lifescienceglobal.com/pms/index.php/JASCM <p>The Journal of Applied Solution Chemistry and Modeling exists primarily for the publication of significant new experimental measurements and theoretical modeling on electrolyte and nonelectrolyte solutions of manufacturing, environmental and pharmaceutical importance. Experimental measurements include thermodynamic and physical properties, acoustic properties, transport properties and phenomena, and phase equilibrium data, including solubility measurements involving organic pollutants and potential medicinal compounds. The journal welcomes theoretical papers dealing with the correlation and prediction of physical, transport, acoustic and thermodynamic properties of liquid mixtures.</p> en-US <h4>Policy for Journals/Articles with Open Access</h4> <p>Authors who publish with this journal agree to the following terms:</p> <ul> <li>Authors retain copyright and grant the journal right of first publication with the work simultaneously licensed under a <a href="http://creativecommons.org/licenses/by/3.0/" target="_new">Creative Commons Attribution License</a> that allows others to share the work with an acknowledgement of the work's authorship and initial publication in this journal.<br /><br /></li> <li>Authors are permitted and encouraged to post links to their work online (e.g., in institutional repositories or on their website) prior to and during the submission process, as it can lead to productive exchanges, as well as earlier and greater citation of published work</li> </ul> <h4>Policy for Journals / Manuscript with Paid Access</h4> <p>Authors who publish with this journal agree to the following terms:</p> <ul> <li>Publisher retain copyright .<br /><br /></li> <li>Authors are permitted and encouraged to post links to their work online (e.g., in institutional repositories or on their website) prior to and during the submission process, as it can lead to productive exchanges, as well as earlier and greater citation of published work .</li> </ul> support@lifescienceglobal.com (Support Manager) support@lifescienceglobal.com (Support Manager) Tue, 25 Feb 2020 00:00:00 +0000 OJS 3.2.1.3 http://blogs.law.harvard.edu/tech/rss 60 The Free-Radical Nonbranched-Chain Initiated Formation of Ethylene Glycol from Methanol–Formaldehyde Solutions https://www.lifescienceglobal.com/pms/index.php/JASCM/article/view/6418 <p class="04-abstract">The mechanism and kinetics are developed for the free-radical nonbranched-chain initiated formation of ethylene glycol in methanol–formaldehyde solutions at formaldehyde concentrations of 0.1–3.1 mol dm<sup>–3</sup> and temperatures of 373–473 K. The experimental concentrations of the free unsolvated form of formaldehyde are given at the different temperatures and total concentrations of formaldehyde in methanol. The experimental dependence of the radiation-chemical yields of ethylene glycol on formaldehyde concentration in γ-radiolysis of methanol–formaldehyde solutions at 373–473 K is shown. At a formaldehyde concentration of 1.4 mol dm<sup>–3</sup> and <em>T</em> = 473 K, the radiation-chemical yield of ethylene glycol is 139 molecules per 100 eV. The effective activation energy of ethylene glycol formation is 25 ± 3 kJ mol<sup>–1</sup>. The quasi-steady-state treatment of the reaction network suggested here led to a rate equation accounting for the non-monotonic dependence of the ethylene glycol formation rate on the concentration of the free (unsolvated) form of dissolved formaldehyde. It is demonstrated that the peak in this dependence is due to the competition between methanol and CH<sub>2</sub>=O for reacting with adduct radical HOCH<sub>2</sub>CH<sub>2</sub>O<sup>•</sup>.</p> Michael M.

A functional complement property of the Temkin isotherm has been studied as a particular case of the common theory of asymptotic complement. This property is shown to give rise to various analytical strategies to be employed for processing or interpretation of the experimental results, e.g. to perform mapping of data obtained in experiments onto a conjugated part of the true isotherm, to judge if presupposed energetic heterogeneity type of the surface really takes place, etc. Experimental data for adsorption of carbon monoxide on gold and of sodium oleate on steel with and without a magnetite coating have been extensively analysed.</p> Michael Vigdorowitsch, Liudmila E.
