Title: Determining the degree of gloss
Date(s): 1938-02
Contributor(s): E.I. du Pont de Nemours & Company (originator)
Description: To determine the degree of gloss in a lacquer or finish, du Pont chemists use a device that measures the amount of light reflected. The light from a constant source is thrown back from the panel into the telescope tube. One half of the 'eyepiece' is illuminated by this reflected radiation, with the other half lighted by a small bulb in the photometer tube attached to the side of the telescope. This light is passed back and forth in the tube until the brightness of the two section meet. The...

This light is passed back and forth in the tube until the brightness of the two section meet. The distance of the light from the 'eyepiece' is then a measure of the amount of light reflected or the gloss.

Title: Determining the drying time of lacquer
Date(s): 1937-12
Contributor(s): E.I. du Pont de Nemours & Company (originator)
Description: How fast a lacquer or finish will dry is determined by the use of plate glass discs coated with the material to be tested and revolved slowly while a thin trickle of sand falls on them from a cone shaped container. It has been found by DuPont chemists that the point at which the sand no longer adheres accurately determines the drying time.

Title: Julian Hill recreating synthesis of first completely synthetic fiber
Date(s): 1941
Contributor(s): E.I. du Pont de Nemours & Company (originator)
Description: 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.

Show moreDr. 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.

Show moreTheodore 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.
