Abstract : Vapor-liquid equilibria data for hydrochloric acid solutions, composition from 7.07 to 37.24 wt pct HCl at temperatures between O and -40C, saturated with sodium chloride are presented. Solubility and solution densities have also been measured and are reported. Evidence has been obtained for the formation of a solid NaCl hydrate in equilibrium with the saturated solutions in the temperature range of -7 to -25C. Quadrupole mass filter sensitivity factors of water to HCl have been determined experimentally and agree with previous thermodynamic predictions to -4 to + or - 14 pct. (Author)
