Description
Summary:The process of rectification purification of arsenic trichloride from hydrolysis products in a hydrogen chloride atmosphere has been considered. The dependence of the relative volatility coefficient of arsenic trichloride on its concentration in hydrochloric acid solution has been investigated. The behavior of the relative volatility coefficient has been compared with the concentrations of HCl and AsCl3. The preservation of the balance equation and the operating line equation of the column under such rectification conditions has been demonstrated.
