Introduction Our recent work indicated that chronic ethanol exposure led to impairing kidney function by significant enhancement of plasma creatinine, urea, and cystatin C levels. In addition, ethanol ingestion resulted in

Abstract  

Excess molar enthalpies of the ternary mixture {x 1 tert-butyl methyl ether (MTBE)+x 2 ethanol+(1–x 1x 2) hexane} and, the involved binary mixtures {x tert-butyl methyl ether (MTBE)+(1–x) ethanol}, {x tert-butyl methyl ether (MTBE)+(1–x) hexane} and {x ethanol+( 1–x) hexane} have been measured at 298.15 K and atmospheric pressure, over the whole composition range, using a Calvet microcalorimeter. The results were fitted by means of different variable degree polynomials.

Excess molar enthalpies of the ternary mixture {x 1 tert-butyl methyl ether (MTBE)+x 2 ethanol+(1–x 1x 2) octane} and the involved binary mixture {x ethanol+(1–x) octane} have been measured at 298.15 K and atmospheric pressure, over the whole composition range, using a Calvet microcalorimeter. The results were fitted by means of different variable degree polynomials.

Abstract  

Excess molar enthalpies of binary mixtures for tributyl phosphate (TBP)+methanol/ethanol were measured with a TAM air Isothermal calorimeter at 298.15 K and ambient. The results for xTBP+(1–x)CH3OH are negative in the whole range of composition, while the values for xTBP+(1–x)C2H5OH change from positive values at low x to small negative values at high x. The experimental results have been correlated with the Redlich–Kister polynomial. IR spectra of the mixtures were measured to investigate the effect of hydrogen bonding in the mixture.

Abstract  

The influence of microporous carbon oxidation on thermodynamic properties of methanol and ethanol adsorbed at 308, 328, and 348 K was investigated. Adsorption mechanisms are suggested and the obtained results are compared with the presented previously for adsorption of methane and carbon tetrachloride on nonoxidised and oxidised microporous carbons.

Ethanol recovery from aqueous fermentation broth by extraction using oleic acid with simultaneous esterification by lipase enzyme was studied. To determine the optimal conditions for the complex process, the ternary system was characterised; binodal curves and tie lines of (ethanol+oleic acid+water) system were determined. Enzymatic esterification of ethanol and oleic acid was carried out and resulted in higher than 50% conversion with simultaneous reduction of ethanol content in the broth. Finally, the effect of the ester product (ethyl oleate) on the distribution of ethanol was determined.

Single screw extrusion of cassava starch was evaluated as a pre-treatment for the enzymatic hydrolysis of the extrudate and fermentation to yield alcohol. The acid concentration, barrel temperature and moisture content showed that all the variables were significant. Increasing acid concentration or barrel temperature induced starch depolymerisation with a higher water solubility index and lower water absorption index. At 20 and 24% moisture contents the cold paste viscosity decreased. As a result of the addition of acid during extrusion cooking the degree of starch hydrolysis resulted in low hot paste viscosity. Acid concentration was significant in the production of reducing sugars. At concentrations above 0.024 N, as the temperature increased, the reducing sugar content also increased. Nevertheless, at concentrations below 0.024 N, the reducing sugar content showed the opposite result. The best yield of alcohol obtained from the extruded starch was 98.7% (0.56 g of ethanol/g starch), which, on average, was 5.7% and 6.8% higher than that obtained from starch extruded without acid and from starch gelatinized by the conventional method, respectively.

Abstract  

In the scope of design and optimise the equipment for alcoholic distillate beverages production, a sufficient knowledge of physical properties and phase equilibria is necessary. In this paper we present the temperature dependence of excess molar volumes of the ternary system ethanol+water+1-propanol at the range 288.15–323.15 K and atmospheric pressure, due to the importance of the 1-propanol among the flavour compounds contained into this type of beverages. Derived properties were computed due to its importance in the study of specific molecular interactions.
