...Pont process old nylon is put into a hot solution. The nylon (a synthetic chemical made from adipic acid and a base related to ammonia called hexamethylene-diamine) dissolves like sugar in hot tea. On cooling, the adipic acid crystallizes out and is purified, while the diamine remains in solution and can be purified by distillation. The two white crystalline chemicals resulting from this unscrambling of nylon fiber are then recombined and polymerized to form the long, tenuous molecules that give nylon its strength and elasticity. This new liquid nylon, identical with the original substance, can be squeezed out into...

...bubbled through a test tube, histamine and vitamin C react with each other, releasing ammonia (the amine part of histamine) and eliminating the irritating chemical.

...like it and grow fat. This announcement from the University of Wisconsin last week concluded its five-year study of the nutritive value of synthetic urea, opened a new era in feeds, perhaps in foods. Urea is a reasonably priced, simple nitrogen compound made chemically from nothing more than ammonia and carbon dioxide. Not a protein, synthetic urea is so closely related to protein that it can replace a major part of the vegetable proteins in cattle feed. Urea is manufactured in large quantity for use in many types of plastics and as a rich fertilizer. Caution: Urea...
