A vapor phase process for making methyl or ethyl nitrite from methanol or ethanol, respectively, by reacting a nitrogen oxide composition with methanol or ethanol.Arthur R. DoumauxJames M. DowneyJoseph P. HenryJohn M. HurtUSUS4353843 * 1981年3月12日 1982年10月12日 Union Carbide Corporation ...
It was found that one parameter, λ, was dependent on solvent only and could be fixed on 2.11 for water, methanol, and ethanol solutions of all kind of electrolytes systems. The other parameter, S , was independent of temperature. The calculated vapor pressures agreed well with the ...
2. To obtain the vapor pressure of methanol and ethanol, the air pressure must be subtracted from each of the measured pressure values. However, for Trials 2-4, even if no methanol was present, the pressure in the flask would have increased due to a higher temperature, or decreased due ...
Since the sum of the partial pressures (xi Pi) equals the total pressure, it’s important to determine the bubble point temperature at each concentration used in constructing the curve. Example This example, for the binary system ethanol-methanol, explains the method for constructing a VLE curve...

Ren et al. presented the VLE data for the binary solutions of 10%–50% [EMIM][DMP] with water, ethanol, and methanol following the bubble point method (Ren et al., 2011). Several researchers documented the thermophysical data for [DMIM][DMP]+H2O that assists in evaluating the efficacy ...
Notably, the nanocomposites with a 5wt% addition of WO3 showed the lowest optimal operating temperature (132 °C), the fastest response/recovery speed (28/9 s), and the highest selectivity against ethanol, methanol, and EG. On the other hand, the nanocomposites with a 10wt% addition of ...

The ITO substrates were cleaned using detergent, acetone, isopropanol, ethanol and deionized water in sequence. CdS buffer layer was deposited by chemical bath deposition7. CdS layers were treated with H2O2 (30 wt%) and 20 mg ml−1 CdCl2 (Aladdin) absolute methanol solution by spin ...
