Liquid–liquid equilibrium data were measured for the ternary systems water + ethyl acetate + diethyl succinate and water + acetic acid + diethyl succinate at 298.15 K and atmospheric pressure. The reliability of the experimental data was confirmed using the Othmer–Tobias correlation. Vapor–li...

Density, viscosity and refractive index of binary mixtures consisting of diethyl succinate + 1-propanol, or +1-butanol, or +1-hexanol have been measured at atmospheric pressure and over the temperature range from 288.15 K to 323.15 K. Excess and deviation functions have been calculated from thes...

Diethyl succinate (DES) is a new and highly efficient carbon dioxide (CO2) absorption solvent. Vapor-liquid equilibrium data for the CO2 + DES system were obtained experimentally from 288.15 K to 318.15 K by the gas-phase recirculation method, and were modeled using the Kritchevsky-Kasarnovsky m...

This work reports experimental phase equilibrium data for the binary systems {CO2(1) + diethyl succinate(2)} and {CO2(1) + ethyl acetate(2)}, and for the ternary systems {CO2(1) + diethyl succinate(2) + ethanol(3)} and {CO2(1) + diethyl succinate(2) + ethyl acetate(3)}. The experiments for the b...

The aim of this study was to develop an efficient thermochemical method for treatment of industrial hemp biomass, in order to increase its bioconversion to succinic acid. Industrial hemp was subjected to various thermochemical pretreatments using 0–3% H2SO4, NaOH or H2O2 at 121–180 °C prior t...

Green oxidation of 2-furaldehyde (furfural) and its homologues were investigated using solid acid catalyst and hydrogen peroxide (H2O2) in aqueous media to form succinic acid (SA), a key chemical that affords wide applications in macromolecular, pharmaceutical and agrochemical industries. Amberl...

The H2O2 degradation of humic acids and lignite from Mír mine (South Moravian region, Czech Republic) resulted in oxidation of aromatic structures and cleavage of aromatic units. The hydrophilic fraction largely dominated the oxidation digest in both parental materials. The presence of polycycl...

Maleic anhydride grafting onto poly(lactic acid) (PLA) was conducted by reactive processing in a torque rheometer according to a 24 factorial design, in which the maleic anhydride and peroxide concentrations, peroxide type and dispersion medium were varied. Physical and chemical properties of mo...

5-Hydroxymethylfurfural was converted to succinic anhydride in 90–92% yield by oxidation with 30% hydrogen peroxide using 10 mol% 1-(alkylsulfonic)-3-methylimidazolium chloride acidic ionic liquid catalysts at 60 °C for 14 h. The acidic ionic liquid catalyst could be reused for four catalytic ...

Pretreatment is a necessary step in the process of biorefinery of lignocellulosics. Here, a novel sequential sugarcane bagasse (SCB) pretreatment method was developed based on potassium peroxymonosulfate (PMS) and alkaline deacetylation (AD) under mild conditions. The co-pretreatment could effic...

The aim of this study was to develop an integrated biofuel (cellulosic bioethanol) and biochemical (succinic acid) production process from rapeseed straw after dilute-acid pretreatment. Rapeseed straw pretreatment at 20% (w/v) solid loading and subsequent hydrolysis with Cellic® CTec2 resulted i...

Fluorescent carbon dots are optically unique materials that have many applications, including photocatalysis, drug delivery, and biosensing. In this work, carbon dots were synthesized in high yields from succinic acid and glycerol using a green, one-step hydrothermal method, and without the addi...

Levulinic acid is produced from the acidic aqueous degradation of 5-hydroxymethylfurfural, with potential applications in bio-value added chemicals synthesis. Here, we report for the first time, the Baeyer-Villiger oxidation of levulinic acid to succinic acid, with hydrogen peroxide and tungstic...

The aim of this study was development of polymeric NPs for efficient macrophage delivery of nevirapine for treatment of AIDS. Emulsification solvent evaporation method was employed to fabricate cellulose acetate butyrate (CAB) NPs containing nevirapine. The effects of quantitative independent va...

In this paper we demonstrate new poly vinyl alkylate homopolymers and copolymers with excellent solubility in scCO2 that can be used as stabilisers for dispersion polymerisation in scCO2. Poly (vinyl acetate) (PVAc) was combined in various ratios with poly (vinyl butyrate) (PVBu) and poly (vinyl...

The broadband rotational spectrum of methyl butyrate from 8 to 18 GHz, recorded using a chirp-pulsed Fourier transform microwave (FTMW) spectrometer, was combined with high resolution FTMW measurements over the 2–26.5 GHz region to provide a comprehensive account of its microwave spectrum under...

We used metabolic modeling to computationally investigate the potential of bacterial coculture system designs for CO conversion to the platform chemical butyrate. By taking advantage of the native capabilities of wild-type strains, we developed two anaerobic coculture designs by combining Clostr...

The work aims to interpret the phase behavior of multi-polymers in super critical CO2 via a spatially dependent structural parameter, the monomer sequence distribution, rather than traditional statistical factors. Well-defined statistical copolymers based on three CO2-philic monomers, vinyl acet...

High pressure phase equilibrium for four binary systems, (CO2 + 2-pentanol, CO2 + vinyl butyrate, CO2 + 2-pentyl butyrate and CO2 + butyric acid), were measured at three temperatures of (313.15, 323.15 and 333.15) K and pressures up to 11 MPa. These four organic compounds are those involved in t...

4-Heptanone is a common volatile constituent of human urine and is of unknown origin. We hypothesised that it arises from in vivo β-oxidation of 2-ethylhexanoic acid (EHA) from plasticisers, similar to formation of 3-heptanone from valproic acid. We investigated urine from individuals with norm...
