Impact of NaOH on the Hydrothermal Oxidation of Guaiacol for the Production of Value-Added Products

Energies, 2022
In this study, the impact of NaOH on the hydrothermal oxidation of guaiacol was investigated. It was found that NaOH significantly accelerated the production of formic acid and acetic acid with H2O2 or CuO as the oxidant.

Thermal and Mechanical Properties of Guaiacol–Fatty Acid–Sulfur Composites

Macromol, 2023
A series of six composites was prepared from the reaction of lignin-derived guaiacol, fatty acids, and sulfur. In this preparation, the organic comonomers undergo C–S bond-forming reactions to establish a highly crosslinked network material in which some

Metabolism of chlorinated guaiacols by a guaiacol-degrading Acinetobacter junii strain [PDF]

Applied and Environmental Microbiology, 1993
The metabolism of chlorinated guaiacols by a pure bacterial strain identified by its ability to use guaiacol as the sole carbon and energy source was studied. This strain, identified as Acinetobacter junii 5ga, was unable to grow on several chlorinated guaiacols and catechols. However, strain 5ga grown on guaiacol degraded 4- and 5-chloroguaiacol and 4,

Predicting the substrate specificity of a glycosyltransferase implicated in the production of phenolic volatiles in tomato fruit [PDF]

, 2011
The volatile compounds that constitute the fruit aroma of ripe tomato (Solanum lycopersicum) are often sequestered in glycosylated form. A homology-based screen was used to identify the gene SlUGT5, which is a member of UDP-glycosyltransferase 72 family ...

Hydrophilic hypercrosslinked polymeric sorbents for the solid-phase extraction of polar contaminants from water [PDF]

, 2010
Three new hypercrosslinked polymers with hydrophilic character arising from hydroxyl moieties in their skeletons have been prepared in microsphere format and applied to the off-line solid-phase extraction (SPE) of polar compounds from water samples.
