Abstract
The liquid - vapour equilibrium is investigated and phase diagrams liquid - vapour are composed for the systems: HCl - SiCl4 and HCl - SiHCl3 within temperature range 203-293 K at total pressure Ptotal = 1.3 atm. The data obtained can be used to choose conditions of HCl desorption from the solutions HCl with chlorosilanes in order to recover HCl from these mixtures.
