21 sty 2021 · The composition of the liquid phase (x 1) and vapor phase (y 1) of the ethanol mole fraction for the binary system ethanol (1) + water (2) at the different pressures of this work was obtained through a calibration curve of composition versus density.
A tetraethyl orthosilicate (TEOS) and water solution (1:4 molar ratio) was dissolved in ethanol and then pumped into an autoclave at 100 bar and 523 K for the SCF reaction process, and at 120...
