Synthesis of Hydrotalcites from Waste Steel Slag with [Bmim]OH Intercalated for the Transesterification of Glycerol Carbonate

open access: yesMolecules, 2020
Ca-Mg-Al hydrotalcites were prepared by coprecipitation from Type S95 steel slag of Shanghai Baosteel Group as supports of ionic liquid in this paper. Five basic ionic liquids [Bmim][CH3COO], [Bmim][HCOO], [Bmim]OH, [Bmim]Br and ChOH were prepared and ...

Dynamic modelling of a fractionation process for a liquid mixture using supercritical carbon dioxide [PDF]

open access: yes, 2001
This work presents a simple dynamic modelling of a process of separation of a quaternary mixture using supercritical CO2. Thermodynamic description is accomplished using efficient available models (SRK equation of state with MHV2 mixing rules).

A review on transesterification of propylene carbonate and methanol for dimethyl carbonate synthesis

open access: yesCarbon Resources Conversion, 2019
Dimethyl carbonate (DMC) is widely applied in various fields according to its outstanding physico-chemical properties, especially as a solvent in electrolyte of lithium-ion batteries. More than 90% DMC in China is industrially produced from the propylene

A life-cycle assessment of poly-hydroxybutyrate extraction from microbial biomass using dimethylcarbonate [PDF]

open access: yes, 2016
Poly-hydroxyalkanoates are an example of biodegradable and biocompatible polymers, produced from renewable raw materials. With respect to other bioplastics the market share of poly-hydroxyalkanoates is still limited because of their commercial costs.

Environmentally-Benign Dimethyl Carbonate-Mediated Production of Chemicals and Biofuels from Renewable Bio-Oil

open access: yesEnergies, 2017
Due to the increasing emission of carbon dioxide (CO2), the development of fuels and chemicals based on renewable resources has attracted much attention. Bio-oil, as a carbon rich material, has been considered as a feedstock for biodiesel production.

Lignin-first fractionation of softwood lignocellulose using a mild dimethyl carbonate and ethylene glycol organosolv process.

open access: yesChemSusChem, 2020
Here we report on a mild lignin-first acidolysis process (140 °C, 40 min) that uses the benign solvent dimethyl carbonate (DMC) and ethylene glycol (EG) as stabilization agent/solvent in order to produce high yield of aromatic monophenols directly from ...

Conformational Preferences of 3-(Dimethylazinoyl)propanoic Acid as a Function of pH and Solvent; Intermolecular versus Intramolecular Hydrogen Bonding [PDF]

open access: yes, 2009
The conformational equilibrium of 3-(dimethylazinoyl)propanoic acid (DMAPA, azinoyl = N^+(O^−) has a weak pH-dependence in D_2O, with a slight preference for trans in alkaline solutions.
