NEW CLOSE-CUT SOLVENTS SPEED PRODUCTION CUICOSIS III SCORES ΟΓ INDUSTRIES Esso Hexane, Heptane and Octane N o w Provide Boiling Ranges of 7°F. to 75°F. Esso S t a n d a r d Oil features t h r e e very narrow cut, commercially p u r e , aliphatic solvents, available at prices as a t t r a c t i v e as those solvents w i t h much wider boiling ranges. Known as Esso Hexane, Esso Hep tane and Esso Octane, these three new solvents have boiling· ranges spreading over 7°F. to 15°F with initial boil ing points of 154°F., 205°F., and 225° F., respectively. In addition to their narrow boiling' ranges, these new sol vents show + 2 5 Saybolt color, pass doctor and corrosion tests and are of such high purity as to be accepted as commercially pure hydrocarbons. The new Esso Solvents offer manufacturers a uniform drying rate, less solvent retention, and less residual odor than solvents with wider boiling ranges. Boon to Seed Oil, Rubber and Textile Manufacturers Because it is a selective solvent for vegetable oils, Esso Hexane is gaining* wide acceptance in soybean and cotton seed mills using the solvent extraction method. It is also proving highly eco nomical, both because of its low initial cost and because its high normal hex ane content permits re-use indefinitely without deterioration. Manufacturers of rubber goods find the new close-cut Esso Solvents desir able in the manufacture of rubber gloves and other products requiring a fast-drying rate. In the textile industry these fast-drying naphthas are more desirable than many other solvents in dissolving rubber to make the cement EVAPORATION

Esso VM & Ρ Naphtha has been reduced to a 45 °F. range, with a 245°F. initial boiling point and a 290°F. dry point. The net result of this narrower range means reduced evaporation loss in storage and speedier processing through elim ination of slow-drying residues. Improved Esso VM&P Naphtha is proving of great benefit to manu facturers of traffic paints, roto gravure and textile printing inks, and to tanners who use it in degreasing leather.
