Production of Diethyl Terephthalate from Biomass‐Derived Muconic Acid
Angewandte Chemie International Edition, 2015AbstractWe report a cascade synthetic route to directly obtain diethyl terephthalate, a replacement for terephthalic acid, from biomass‐derived muconic acid, ethanol, and ethylene. The process involves two steps: First, a substituted cyclohexene system is built through esterification and Diels–Alder reaction; then, a dehydrogenation reaction provides ...

ECS Meeting Abstracts, 2016
The production of biorenewable chemicals has significantly evolved over the past years and numerous processes either have reached commercial stage or are close to commercialization.1 Recently, the biological synthesis of diacids has been receiving greater attention for the manufacture of green polyesters and polyamides.2 Muconic acid, an unsaturated C6

Microbial production of cis, cis-muconic acid from benzoic acid
Applied Microbiology and Biotechnology, 1988The authors isolated numerous microorganisms with the capacity to assimilate large amounts of benzoate from many soil samples. Several of them were selected and subjected to mutation mainly by ultraviolet irradiation. One mutant lacking active muconate-lactonizing enzyme, the parent strain of which was identified as belonging to the genus Arthrobacter,

Identification of Muconic Acids in Bleach Plant Effluent
hfsg, 1996Muconic acids derived from guaiacol (4) were identified in ethyl acetate extracts of samples of effluents from 100% chlorine dioxide bleaching. Concentrations were estimated to be in the range 7.5-26 g/tonne. Chlorinated muconic acids derived from guaiacol were not found, but other muconic acids are likely present, both in the low molecular mass ...

AbstractThe hydrogenation of muconic acid (MA), a biobased platform molecule, offers a sustainable pathway to adipic acid (AA), a key industrial dicarboxylic acid. In this study, we explore the catalytic transfer hydrogenation (CTH) of muconic acid and muconates using ionic ruthenium complexes. Unlike previous approaches, our method aims to selectively

Assessment of trans, trans-muconic acid in human seminal plasma
Andrologia, 2001Trans, trans-muconic acid (tt-MA) is one of the most important metabolites of benzene, a pollutant ubiquitously distributed in ambient air and classified in 1982 as a group I carcinogen. For its sensitivity and specificity, tt-MA excreted in urine is considered a good biological marker of benzene exposure.

Muconic Acid as a Key Biorenewable Platform Molecule
Abstract: Muconic acid (2,4-hexadienedioic acid) has been proposed as a valuable biobased platform molecule for the future chemical industry. It can be accessed from biorenewable feedstock (lignin or sugars) via both chemical and biotechnological means and be transformed into a broad spectrum of both drop-in and new molecules with a variety of ...Ver Elst, Céderic, Maes, Bert

Synthesis of levulinic acid and derivatives from muconic acid
One of the major challenges of our time is the transformation of our petroleum based industry towards a more sustainable model based on other carbon sources. Indeed, the global warming combined with an ever growing world population make this matter more actual than ever.openaire +2 more sources
