Urinary Benzene Biomarkers and DNA Methylation in Bulgarian Petrochemical Workers: Study Findings and Comparison of Linear and Beta Regression Models [PDF]

, 2012
Chronic occupational exposure to benzene is associated with an increased risk of hematological malignancies such as acute myeloid leukemia (AML), but the underlying mechanisms are still unclear.

Renewable Adipic Acid From the Hydrogenation of Trans,Trans-Muconic Acid: Selection of a Three Phases Kinetic Model

Chemical Engineering Transactions, 2017
The hydrogenation of muconic acid to adipic acid is studied in a three phases slurry reactor. This is the last step of a novel biotechnological process which, starting from lignocellulosic biomass, allows the production of renewable PA 6,6. A new Pt/C 5%

Muconic Acid Esters as Bio-Based Acrylate Mimics

Polymer Chemistry, 2019
The synthesis of polymers from radical polymerization of dialkyl muconates, a renewable monomer that is readily available from biofermentation, is described. Polymuconates are scarcly described in literature, and were previously believed to polymerize only sluggishly.

Further insights on predictors of environmental tobacco smoke exposure during the pediatric age [PDF]

, 2019
Background: The smoking ban in public places has reduced Environmental Tobacco Smoke (ETS) exposure for non-smokers, but despite this, domestic environments still remain places at high risk of exposure, and, today, about 40% of children worldwide are ...

Cu‐Catalyzed Aerobic Oxidative C─C Cleavage in Lignin‐Derived Oligomers and Biological Funneling of the Monomeric Products

Angewandte Chemie, Volume 138, Issue 2, 9 January 2026.
Catalytic aerobic oxidation under aqueous alkaline conditions promotes C–C cleavage in pine‐ and poplar‐derived lignin oligomers, accessing high yields of aromatic monomers. The monomeric phenols obtained from this process then undergo effective biological conversion into cis,cis‐muconic acid and 2‐pyrone‐4,6‐dicarboxylic acid using engineered strains ...

Reactive extraction of muconic acid by hydrophobic phosphonium ionic liquids - Experimental, modelling and optimisation with Artificial Neural Networks

Heliyon
Muconic acid is a six-carbon dicarboxylic acid with conjugated double bonds that finds extensive use in the food (additive), chemical (production of adipic acid, monomer for functional resins and bio-plastics), and pharmaceutical sectors.

Reference intervals for urinary cotinine levels and the influence of sampling time and other predictors on its excretion among italian schoolchildren [PDF]

, 2018
(1) Background: Environmental Tobacco Smoke (ETS) exposure remains a public health problem worldwide. The aims are to establish urinary (u-) cotinine reference values for healthy Italian children, to evaluate the role of the sampling time and of other ...

Fast pyrolysis of muconic acid and formic acid salt mixtures [PDF]

Journal of Analytical and Applied Pyrolysis, 2015
Abstract Lignocellulosic feedstocks are a potential renewable resource for the production of liquid fuels and chemicals. As a major by-product of the pulping industry, lignin is an underutilized source of organic carbon in lignocellulosic biomass. Residual lignin remaining in pulp after cooking of lignocellulosic biomass is typically removed during ...
