Stability, non-fiammability and easy recovery are other features of these solvents for development and process work. FOR POWERFUL, fast-penetrating solvents with selective action covering a wide scale of boiling ranges, specify Du Pont Chlorinated Solvents! The lowest in the series boils at -23.8°C. and the highest at 160.5°C—a range not ap proached by any other related group of non-flammable or moderately flammable solvents. These solvents readily dissolve oils, fats, waxes, tars, natural resins, free alkaloids. Low surface tension and high wetting power contribute to this effect. They're miscible with alcohol, ether and other organic solvents. Yet sugars, ordinary plant acids and water are insoluble or practically insoluble in them. And these solvents can be recovered easily and economically from extracted oils, meals and residues. Du Pont Chlorinated Solvents find wide use in the ex-
traction field. They are also used extensively in Che dry cleaning, metal degreasing, textile processing, refrigerat ing, drug and paint fields. Each of these solvents has properties which make it exceedingly useful and efficient for specific types of work. Detailed information about these se lective solvents is given in the Du Pont technical bulletin "Chlorinated Hydro carbons.''
