Updated definition of the three solvent descriptors related to the van der waals forces in solutions was written by Laffort, Paul. And the article was included in Open Journal of Physical Chemistry in 2018.Synthetic Route of C28H38O19 This article mentions the following:
Innovative viewpoint on the older topic of the van der Waals forces, is of interesting and significant issue to be concerned in both the fields related to the fundamental investigation and thus valuable in guiding the new physio-chem. phenomena and processes for both academic research and practical applications. The intermol. Van der Waals forces involved in solutions have been recently deeply reconsidered as far as the solute side is concerned. More precisely, the solute descriptors (or parameters) exptl. established, have been accurately related to mol. features of a Simplified Mol. Topol. In the present study, an equivalent result is reached on the solvent side. Both exptl. parameters have been obtained simultaneously in previous Gas Liquid Chromatog. studies for 121 Volatile Organic Compounds and 11 liquid stationary phases, via an original Multiplicative Matrix Anal. In that exptl. step, five groups of forces were identified, two of hydrogen bonding and three of Van der Waals: 1. dispersion (London), 2. orientation or polarity strictly speaking (Keesom), and 3. induction-polarizability (Debye). At this stage, an attempt of characterization the solvent parameters via the SMT procedure has been limited to those related to the Van der Waals forces, those related to the hydrogen bonding being for now left aside. In the experiment, the researchers used many compounds, for example, (2R,3R,4S,5R,6R)-2-(Acetoxymethyl)-6-(((2S,3S,4R,5R)-3,4-diacetoxy-2,5-bis(acetoxymethyl)tetrahydrofuran-2-yl)oxy)tetrahydro-2H-pyran-3,4,5-triyl triacetate (cas: 126-14-7Synthetic Route of C28H38O19).
(2R,3R,4S,5R,6R)-2-(Acetoxymethyl)-6-(((2S,3S,4R,5R)-3,4-diacetoxy-2,5-bis(acetoxymethyl)tetrahydrofuran-2-yl)oxy)tetrahydro-2H-pyran-3,4,5-triyl triacetate (cas: 126-14-7) belongs to tetrahydrofuran derivatives. Solid acid catalysis, and the advantages often associated with their use, have been proved equally efficient for the synthesis of tetrahydrofurans or furans. Oxidations have also proved to be valuable and efficient approaches to chiral tetrahydrofuran derivatives.Synthetic Route of C28H38O19
