Zhenjiang site will benefit from the cleanest and most sustainable patented technology based on a fully integrated ex-catechol and guaiacol
production value chain, including an exclusive water treatment process.
and syringols), and catechol occur in the SW quadrant together with an aliphatic marker of fresh plant material (Al13).
The development of oxidative stress during the coffee-drying process can be controlled more efficiently in pulped natural coffee by the early action of guaiacol
peroxidase during the drying process.
Oxidation of guaiacol
by myeloperoxidase: a two-electron-oxidized guaiacol
transient species as a mediator of NADPH oxidation.
2009) using a mixture of EO components supplementation including thymol, eugenol, vanillin, guaiacol
, and limonene, and in vitro studies using thymol and THY (Castillejos et al.

Some of the phenolic compounds are guaiacol
and syringol which are very characteristic in smoked fish .
The majority is synthesized in chemistry labs, and typically made from lignin, a constituent of wood left over from the paper-making industry, or guaiacol
, which is derived from wood creosote.
Reaction of chromic acid with lignin model compounds such as guaiacol
and catechol indicates that chromic acid photostabilizes wood by reacting with lignin to create photostable lignin complexes enabling energy transfer or energy emittance from wooden surfaces.
Para a determinacao da atividade enzimatica, 0,5 mL do sobrenadante foram misturados a 1,5 mL de tampao fosfato a 200 mM, pH 6,5, 0,5 mL de guaiacol
a 190 mM e 0,5 mL de [H.
Higher molecular weight compounds seemed to shift the range of boiling temperatures higher: it required higher temperatures to distill phenol and guaiacol
from the BCD mixture than from the synthetic mixture.
This category includes phenol, tannic acid, and guaiacol
