The densities of 1-butanol and 1-pentanol were measured in aqueous solutions of dodecyltrimethylammonium bromide and dodecyldimethylamine oxide and the partial molar volumes at infinite dilution of the alcohols in aqueous surfactants solutions were obtained. The observed trends of this quantity as a ...
The behavior of the standard partial molar heat capacities of alcohols in micellar solutions in the region above the cmc and below the structural transition was explained using a previously reported mass-action model for the alcohol distribution between the aqueous and the micellar phase and the ...
Excess molar enthalpies,densities,and speeds of sound at the temperatures(283.15,298.15,313.15)K are reported for the binary mixtures 6,6-dimethyl-2-methylenebicyclo[3.1.1]heptane(beta-pinene)+ 1-pentanol and beta-pinene + 2-pentanol.Exc... AF Ribeiro,E Langa,AM Mainar - 《Journal of Chemi...
Discuss in terms of intermolecular forces. Consider the following two compounds: C5H11SH, 1-pentanethiol C5H11OH, 1-pentanol (a) Which compound has the higher molar mass? (1-pentanethiol or 1-pentanol?) (b) Which compound has the higher bo...
From the 4-methyl-2-pentanol reaction, gas chromatographic analyses showed the formation of acetaldehyde, acetone, 2-methyl-2-propanal and 4-methyl-2-pentanone, with molar formation yields of 37±6, 26±3, 11.1±1.2 and 25±2%, respectively. In situ atmospheric pressure ionization mass ...
Density and viscosity of the binary liquid mixtures of (THFA + cyclopentanol, THFA + 1-pentanol and cyclopentanol + 1-pentanol) have been measured as a function of composition range at 293.15, 303.15, 313.15K. From density and viscosity data, the values of excess molar volume (VE), the ...
For the solubility of each solvent mixture studied, the mole fraction solubility of terephthaldialdehyde in mixed solutions increased with increasing temperature and mass fraction of ethanol, isopropanol, ethyl acetate or isopentanol for the four systems of (ethanol+N,N-dimethylformamide), (isopropanol+...
and then the mass fraction obtained in 99.50% of amyl acetate under reduced pressure; 3) acetic acid and methanol pentyl ester by catalytic distillation reaction of 2-pentanol and 3-pentanol mixture; transesterification reaction temperature is 62 ~ 80 ℃, molar ratio of methanol, amyl acetate is...
The apparent molar volume of pentanol in the ternary system was analyzed using a mass-action model for the alcohol distribution in micellar solutions. The partial molar volume of alcohol bound to the micelles and the ratio between the binding constant and the aggregation number of the surfactant ...
1-pentanol at a concentration of 0.1 M adsorbed on the lipid vesicles leading to more dissipative vesicle layers. Furthermore, 0.1 M 1-pentanol induced membrane disorder as inferred from the large decrease in main phase transition temperature. After heating and cooling scans, mass loss of the la...
