...president suggested an interesting comparison between his own field and business administration. Chemistry, as a practical profession, evolved from alchemy only when the chemist Boyle wrote a book revealing the known facts candidly and ridiculing the veil of secrecy which had caused distrust of the whole science. "At present," said President Conant, "we are lifting the veil from the field of business and economics and it too is emerging as a highly useful profession...
...process is feasible because synthetic chemistry has cheapened the manufacture of malic acid, the substance which gives apples their flavor. Dr. Charles Raymond Downs, Manhattan consulting chemist who presented the wine-aging idea, passes a mixture of air and benzene over a catalyst to get maleic acid. Other action turns the maleic to malic acid, which combines with calcium to form the desired calcium malate...
Plastics. Carleton Ellis, Montclair, N. J. research chemist, surveyed modern developments in synthetic resins. Best known ones are those made from phenol and formaldehyde (Bakelite, Durez), urea and formaldehyde (Unyte, Plaskon, Beetle), glycerol and phthalic anhydride (Glyptal, Rezyl), and vinyl compounds (Vinylite). Other trade names: Tornesite, Thiokol, Plioform, Victron. With Bakelite starting the grand march they have been widely used in small molded shapes. Late developments make it possible to mold large objects (chair backs and legs, table tops, radio cabinets) from plastics. Tanks nine feet in diameter have been molded from Haveg, a phenol-aldehyde. Textiles can be impregnated...
Zein. The director of the Corn Industries Research Foundation, Chemist Harry Everett Barnard, urged chemists to invent uses for zein, a protein left over as a by-product from the corn-refining industry. Arthur Dehon Little, Cambridge industrial chemist, is already experimenting. Zein resembles cellulose and cellulose derivatives in certain ways. It can be mixed with them, as in plastics. It resists water, decay and flames, has advantages as an adhesive, in sizing paper and textiles, and in finishing leather. Chemist Morris Omansky, Boston consultant, reports zein useful as a reinforcing compound for rubber manufacture, arid Dr. Barnard thinks...
Synthetic Rubber. E. I. du Pont de Nemours &. Co. decided the time was propitious to announce that its synthetic rubber was good enough for all, and cheap enough for some, industrial uses. Dr. Wallace Hume Carothers, research chemist, appeared for the company and said: "Starting with vinylacetylene, a compound made available through the discoveries of Dr. J[ulius] A[rthur] Nieuwland of Notre Dame University, du Pont chemists have synthesized a large number of new compounds closely related to isoprene. At least two of them, chloroprene and bromo-prene, are enormously superior to any other materials as starting points...
