ABSTRACT
Experimental equilibrium data of the systems water + NaCl or KCl+ 2-methyl 2-propanol are determined experimentally at boiling conditions and 101.3 kPa. The results obtained permit a study of the shape and different regions of their equilibrium diagrams. A comparison with similar diagrams of other alcohols is made, demonstrating that the ability of NaCl and KCl to split the water + alcohol mixture into two liquid phases increases with temperature and that NaCl splits the alcohols from water in the following order: 2-methyl 2-propanol greater than1-propanolgreater than 2propanol.
