Complexes formation between aluminum ions and diglycolic and thiodiglycolic acids was studied at 25°C in 0·5 M NaClO4 by potentiometric measurements. In the investigated concentration ranges (−log|H+|
Mixed-ligand Ni(II) complexes involving thiodiglycolate(2−) anion (tdga) and nitrogen-donor ligands in the coordination sphere have been prepared. The complexes of composition [Ni(bpy)(tdga)(H2O)] · 4H2O (1), [(en)Ni(μ-tdga)2Ni(en)] · 4H2O (2), [Ni(phen)(tdga)(H2O)] (3), [Ni(1,8-dan)(tdga)(H2...
The association between vinyl chloride monomer (VCM) exposure and DNA damage has been established. However, the relationship between individual exposure and DNA single strand breaks was limited. Since environmental monitoring may not reflect the actual exposure, a useful marker of exposure is ne...
A sensitive capillary electrophoretic method was developed for the determination of thiodiglycolic acid (TDA) in urine which avoids the pretreatment of the urine sample. Several carrier electrolytes were examined. The most suitable carrier electrolyte system consisted of potassium hydrogen phtha...
BackgroundSchool-aged children living in the vicinity of vinyl chloride (VCM)/polyvinyl chloride (PVC) factories may have an increased risk of exposure to hazardous air pollutants.
The effect of exposure to vinyl chloride monomer (VCM) on susceptibility to hepatotoxicity in children is unknown, although experimental studies have demonstrated a significantly increased risk of hepatocellular carcinoma in rodents exposed to VCM in early life. Epidemiological studies have reve...
BackgroundOccupational and experimental studies have revealed that high vinyl chloride monomer (VCM) exposure is associated with non-alcoholic fatty liver disease (NAFLD). Epidemiological study reported that children living near a petrochemical complex have elevated exposure levels of urinary th...
In our previous paper (Chem. Eng. Process., 102 (2016) 27), a comprehensive theoretical study of membrane reactors for isoamyl acetate synthesis was presented. Here, as an extension of that work, the performance of a batch pervaporation membrane reactor was experimentally verified. In order to s...
The palladium-catalyzed acetoxylation of cyclic dialkyl allyl phosphonates is effected using palladium chloride as catalyst, in the presence of isopentyl nitrite in acetic acid under an oxygen atmosphere. The proposed mechanism for the reaction involves a palladium nitro–nitroso redox couple.
Excess molar volumes for binary mixtures containing vinyl acetate + methyl acetate, +ethyl acetate, +propyl acetate, +isopropyl acetate, +butyl acetate, +isobutyl acetate, +pentyl acetate, +isopentyl acetate have been determined from density measurements at 298.15 K using an Anton Paar DMA 58 vi...
The objective of this study was to evaluate the potential anticonvulsant effect of isopentyl ferulate, a new ester derived from ferulic acid in mice (Mus musculus) subjected to two models of induced seizures. According to the results obtained, the IF at doses of 25, 50 and 75 mg/kg (i.p.) showed...
Essential oils have played a prominent role in research on natural products, due to the high level of bioactive constituents, which include those derived from phenylpropanoids or terpenoids. This study aimed to evaluate the antioxidant capacity of isopentyl ferulate (IF) employing in vitro exper...
Isobaric vapor–liquid equilibria were determined at 101.3 kPa for methanol+pentyl acetate, methanol+isopentyl acetate, and vinyl acetate+pentyl acetate. The thermodynamic consistency of the experimental data was checked by using a modified Dechema test. The activity coefficients were correlated...
Pressure–composition isotherms of phase equilibria for the CO2 + isoalkyl acetate systems are investigated in the static method at five temperatures of (313.2, 333.2, 353.2, 373.2 and 393.2) K and pressures up to 18.24 MPa. The CO2 + isobutyl acetate, CO2 + isopentyl acetate and CO2 + isooctyl ...
The reactive distillation process regarding ionic liquid-catalyzed transesterification for iso-pentyl acetate production is attracting increasing attention owing to outstanding properties of green homogeneous catalysts. This work investigates the economics and controllability of conventional rea...
In this work a water film non-thermal plasma reactor is combined with an aerobic biological reactor to treat water contaminated by 1,4-dioxane. The plasma reactor converted 1,4-dioxane to organic products including ethylene glycol, ethylene glycol monoformate, ethylene glycol diformate, 1,4-diox...
In this article we have studied the photophysics of an alkaloid harmaline in 1,4-dioxane-water mixtures. It was known that the microstructure of this binary mixture changes upon varying the mole fraction of 1,4-dioxane in mixture. We have observed that the photophysics of harmaline in 1,4-dioxan...
In this paper, the hydrate formation pressure values for the systems of water + CO2, water + cyclopentane + CO2, water+1,4-dioxane + CO2, and water+1,4-dioxane + cyclopentane + CO2 were obtained at different mass fractions of 1,4-dioxane (5.1, 10.17, and 25.31) by using the isochoric pressure se...
A rotating advanced oxidation contactor (RAOC) equipped with activated carbon (AC)/TiO2 composite sheets for 1,4-dioxane removal from biologically treated landfill leachate (BTLL) was developed. The performance of the RAOC in 1,4-dioxane removal was compared to that of a TiO2 slurry reactor by e...
1,4-Dioxane has historically been used to stabilize chlorinated solvents and more recently has been found as a contaminant of numerous consumer and food products. Once discharged into the environment, its physical and chemical characteristics facilitate migration in groundwater, resulting in wid...
