Kinetics of the ozonation of muconic acid in water

Journal of Hazardous Materials, 2006
The removal of muconic acid (specifically trans-trans-butanedioc acid) with ozone from water has been studied for kinetics purposes. Concentrations of muconic acid of 4.4x10(-4)M are completely removed with ozone in less than 14 and 9 min at pH 3 and 7, respectively, and 3x10(-4)M of ozone in the gas.

Microbial production of cis,cis-muconic acid

Journal of Biotechnology, 1990
Abstract Research on the microbial production of cis,cis -muconic acid is reviewed. Firstly, reports using various microorganisms are described. Secondly, our research on the production of cis,cis -muconic acid from benzoic acid using a total bioreactor system including downstream processing is shown.

Biological Production of Muconic Acid via a Prokaryotic 2,3‐Dihydroxybenzoic Acid Decarboxylase

ChemSusChem, 2014
AbstractNon‐oxidative decarboxylases belong to a unique enzyme family that does not require any cofactors. Here we report the characterization of a 2,3‐dihydroxybenzoic acid (2,3‐DHBA) decarboxylase (BDC) from Klebsiella pneumoniae and explore its application on the production of muconic acid.

Homogeneous iron-catalyzed photochemical degradation of muconic acid in water

Water Research, 2007
Iron photochemical oxidation has been used to remove muconic acid from water. Two different light systems were used: black lamps and solar irradiation. The effect of iron concentration, intensity of incident radiation, pH and presence of oxalic acid was investigated.

Radical polymerization of muconic acid and ethyl muconate

Journal of Polymer Science: Polymer Chemistry Edition, 1977
AbstractMuconic acid (Mu‐acid) was found to polymerize to trans‐1,4‐poly(Mu‐acid) with the use of azobisisobutyronitrile (AIBN) as an initiator. Similarly, a muconic acid derivative, ethyl muconate (EMu), was readily polymerized through a trans‐1,4 addition mechanism by the use of a radical or anionic catalyst, but did not polymerize when a cationic ...

Characterization of crystalline muconic acid polymorphs

2017 42nd International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz), 2017
Muconic acid is known to exhibit three isomeric forms, but the cis-trans isomer is largely uncharacterized. Using a combination of X-ray diffraction, solid-state density functional theory, and terahertz spectroscopy, a detailed solid-state structural investigation was performed for cis-trans muconic acid.

Reactive extraction of cis,cis-muconic acid

Fluid Phase Equilibria, 2015
Abstract The reactive extraction (RE) of carboxylic and dicarboxylic acids, such as cis,cis‑muconic acid (CCMA), is a promising integrated approach towards an efficient downstream processing development. Dicarboxylic acids have a high potential to be used as precursors for polymerization reactions or as monomers for new and innovative polymers and ...
