ion transport with charge protected and non charge protected cations using the compensated arrhenius formalism part 2 relationship between ionic conductivity and diffusion
Journal of Physical Chemistry B, 2012Co-Authors: Matt Petrowsky, Allison M Fleshman, Dharshani N Bopege, Roger FrechAbstract:Temperature-dependent ionic conductivities and cation/anion self-diffusion coefficients are measured for four electrolyte families: TbaTf-linear primary alcohols, LiTf-linear primary alcohols, TbaTf-n-alkyl Acetates, and LiTf-n-alkyl Acetates. The Nernst–Einstein equation does not adequately describe the data. Instead, the compensated Arrhenius formalism is applied to both conductivity and diffusion data. General trends based on temperature and alkyl chain length are observed when conductivity is plotted against cation or anion diffusion coefficient, but there is no clear pattern to the data. However, plotting conductivity exponential prefactors against those for diffusion results in four distinct curves, one each for the alcohol and Acetate families described above. Furthermore, the TbaTf-alcohol and TbaTf-Acetate data are “in line” with each other. The conductivity prefactors for the LiTf-alcohol data are smaller than those for the TbaTf data. The LiTf-Acetate data have the lowest conductivity prefactor...

preparation of monolignol γ Acetate γ p hydroxycinnamate and γ p hydroxybenzoate conjugates selective deacylation of phenolic Acetates with hydrazine Acetate
RSC Advances, 2013Co-Authors: Matthew Regner, Fachuang Lu, Allison Mohammadi, Timothy J Pearson, John RalphAbstract:We report here a reliable and facile synthesis of a range of monolignol γ-p-hydroxycinnamate (including p-coumarate, ferulate, and caffeate), γ-Acetate, and γ-p-hydroxybenzoate conjugates, many not previously reported, that are either putative intermediates in the biosynthesis of natural lignins or new monomer-conjugates destined for upcoming designer lignins. The key was the development of a highly selective deacylation approach for phenolic Acetates; i.e., a method that cleaves phenolic Acetates while leaving the sensitive monolignol ester conjugates intact.
