摘要：
The liquid-vapor equilibria in the ASCl(3)-HCl-H2O system have been studied by a flow method at high hydrogen chloride concentrations (above 20 wt %) over the entire arsenic trichloride solubility range at temperatures from 25 to 105 degrees C and a pressure of 1.013 MPa. The composition effects on the parameters of the liquid-vapor equilibria have been assessed, and the conditions for the most effective recovery of arsenic trichloride from hydrochloric acid solutions by distillation were established.
