1 Julian Hill recreating synthesis of first completely synthetic fiber 1941 E.I. du Pont de Nemours & Company (originator) Probably the most dramatic moment in DuPont research history is re-enacted above-the birth of the first completely synthetic fiber, impractical for commercial use but true forerunner of nylon itself. Here chemist Julian Hill shows how he pulled molten sample of material from a laboratory test tube at the company's Experimental Station near Wilmington, Delaware. The molasses-like mass stuck to the glass stirring rod and was drawn out into a thin fiber.

2 Preparing a monomer for polymerization study 1950/1959, 1950, 1959 E.I. du Pont de Nemours & Company (originator) In a fundamental research project, a scientist in the Central Research Department at the DuPont Company's Experimental Station, prepares a monomer that will later be used in a polymerization study. One of the components boils at 29 degrees below zero and must be cooled to keep it in liquid form. This causes the frost or ice formation on the tubes in the picture. The coolant is a mixture of dry ice and acetone.

Theodore Hoffman, director of the DuPont perfume laboratories and an outstanding authority on perfumes, applies the last test to a bottle of perfume-which depends on the olfactory sense and not on formulas, at the New Brunswick, New Jersey factory of E.I. du Pont Nemours & Company. For perfume making is both an art and a science. The materials are supplied by he chemist-whether he extracts them from natural sources or creates synthetic components. But the blending calls for the perfumer who works by inspiration. It takes a great artist to create a rare perfume, for not enough is known of the perfumers work to proceed by scientific formula. Until the lilac odor was synthesized-one of the outstanding achievements of the chemical laboratory in perfumery-there was no lilac perfume, for no satisfactory means has ever been found of extracting this natural oil. Moreover, there is no known natural extract so sweet or so peculiarly powerful in odor as synthetic lilac. Chemistry converts volatile turpentine into fragrant lilac rivaling natures illusive floral fragrance.

Dr. Paul W. Morgan of DuPont's Textile Fibers Pioneering Research Laboratory demonstrates the making of nylon, instantaneously, at room temperature, without any apparatus other than a drinking glass, a small jar or beaker. Practical commercial manufacture of nylon requires high temperatures, precision controls and complex and expensive equipment. Dr. Morgan shows here how a nylon rope can be drawn from a beaker when a solution of a fast reacting diacid chloride in a water immiscible solvent is brought into contact with an aqueous solution of an aliphatic diamine. A film of high polymer forms where the two solutions meet which is called the interface. The film can then be pulled from the interface immediately and as if by magic, it is continuously replaced to form a long endless cord of polyamide-hence the nylon rope trick. This particular method of making nylon is an invaluable laboratory tool to researchers and teachers in chemistry because permits polymeric experimentation which are both inexpensive and uncomplicated.
