The process by which musk is formed in the body of the musk deer is recapitulated in the making of synthetic musk by the chemist. It is probably that natural musk is formed in the animal by transformation of fats or oils. Here, treated castor oil...
Synthetic detergent, left, produces billowy suds in hard water, while soap, right, forms insoluble curds. DuPont introduced the synthetics in America in 1933. Now the Organic Chemicals Department produces a number of synthetic detergents and other...
The durability of synthetic resin finishes, even under the most unusual conditions, was shown at the former DuPont Exhibition in the New York Museum of Science and Industry, Rockefeller Center. On top of the hardwood disc, covered with a synthetic...
Large bottles of terpineol, the chief constituent of synthetic lilac perfume. Reflected in the vessels of crystal clear oil are the large drums of the raw materials for perfume manufacture. Until the lilac odor was synthesized-one of the...
An intermediate step in making synthetic lilac perfume-the distillation of terpineol. The crude terpineol oil is vaporized in a vacuum still, the vapors are purified in a fractionating column, cooled in a condenser and finally the pure terpineol...
An intermediate step in making synthetic lilac perfume-crude terpin hydrate flowing into the large vat where it is filtered and purified. Until the lilac odor was synthesized-one of the outstanding achievements of the chemical laboratory in...
The E. I du Pont de Nemours & Company minute books document an important era in the history of the company from just before the turn of the twentieth century through the 1930s. The DuPont Company in this time went through many changes in structure...

Nordel is a new type of synthetic rubber resistant to sunlight, weathering and ozone determination. DuPont is producing it in a recently completed plant at Beaumont, Texas. The new rubber, a product of the company's pioneering research program, is...
Neoprene sheet becomes a rope prior to cutting and packing. Here, a DuPont foreman checks texture of the material at the 50 million pound neoprene plant near Montague, Michigan. The only general purpose synthetic rubber in commercial manufacture in...

Resurfacing material is made by mixing neoprene latex with a special kind of water setting cement and an aggregate of finely crushed stone. Man with brush is applying a prime coat of neoprene latex to secure a tight bond to the old concrete....
Work soles made of DuPont's synthetic rubber, neoprene are popular in many industries, but especially so among roofers. They are surefooted, abrasion resistant and long wearing. Neoprene crepe is much more resistant to oxidation than natural rubber...
These paper barrel covers are used here in an eastern chemical plant to keep materials clean and dry during temporary storage or during transport from point to point within the plant. They are made of no ordinary paper however; barrels are often...
Charging machine for water gas generator in which coke is heated and through which air and steam are blown to produce a crude mixture of hydrogen and carbon monoxide at the Belle WV plant of E.I. du Pont Nemours & Company. This is one of the...

Within the last few years, the chemist has developed a new kind of soap. Starting with ordinary vegetable and animal oils, the chemist now makes fatty alcohols which, in combination with sulfuric acid and other chemicals gives a new class of...
To make a test of the new salt water soap developed for the Army say Louise Feldman left, and Frances Montgomery, chemists in the DuPont Technical Laboratory at Deepwater Point, New Jersey. Miss Montgomery, using the new soap khaki colored for...
Storage section of the E.I. du Pont Nemours & Company laboratory at New Brunswick, New Jersey where essential oils of myriad odors are stored for use in synthetic perfume experiments.
