Data on the activity of acetone for the binary system acetone‐formamide, and a specific ternary system cellulose acetate‐acetone‐formamide are given for the temperature range 0 to 30°C. A method of determining concentration changes occurring on the membrane surface during the evaporation stage in the process of making cellulose acetate reverse osmosis membranes is illustrated.
