The vapor‐liquid equilibrium of the binary system was determined, especially in the range of low water concentrations. The purity of anhydrous hydrogen fluoride used in this work was 9N (99.9999999%) with a conductivity of (water concentration of 0.033 ppm). We elucidated that the vapor‐liquid equilibrium of the binary system obeyed Raoult's law below (18 ppm) water concentration. We determined the activity coefficients of and at the boiling point of the binary system .
