Died, Rev. Dr. Julius Arthur Nieuwland, 58, chemist, priest of the Roman Catholic Congregation of the Holy Cross, onetime dean of Notre Dame University's College of Science; of a heart attack; in Washington, D. C. His researches gave mankind Lewisite (deadliest of war gases) and chloroprene (artificial rubber...
...Villanova College last week went the Rev. Julius Arthur Nieuwland, Belgian-born professor of organic chemistry at Notre Dame, to receive the Mendel Medal as Catholic scientist-of-the-year for his researches on acetylene which led to the development of synthetic rubber (TIME, Nov. 16, 1931 et seq.). Before the ceremony a newshawk questioned the famed priest on another outgrowth of his researches, lewisite, only war gas deadlier than mustard gas. Said Father Nieuwland...
...chemists tried to make synthetic rubber by picking latex apart, deciding what it was composed of, reassembling the elements. It might have been better to look for a compound which would serve the purpose of rubber rather than duplicate its composition. The synthetic rubber which grew out of the Nieuwland researches is 40% chlorine, not an ingredient of natural rubber at all. At a chemistry symposium in Rochester, during the winter of 1925, Father Nieuwland read a paper on the formation of divinyl acetylene from acetylene and cuprous ammonium chloride. Du Font's Dr. Elmer K. Bolton was there...
...Father Nieuwland helped the du Pont group under Wallace H. Carothers prepare the monovinyl, suggested catalysts for changing it to chlorobutadiene. Carothers found that after standing ten days in a closed vessel, chlorobutadiene became an elastic mass like rubber. Thus Duprene. Last summer du Pont announced that Duprene automobile tires were satisfactory in every respect (TIME, July...
...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 for the synthesis of rubber." DuPrene, derived from chloroprene, is the synthetic...
