This book was released on 1967 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: Certain inorganic fluorides were reviewed for their chemical, physical and toxicological properties. The compounds are nitrogen trifluoride; tetrafluorohydrazine; chlorine trifluoride; bromine pentafluoride; oxygen difluoride; hydrogen fluoride, and fluorine. Seeds and seedlings of bean, corn, pea, squash and sudan grass were exposed to air or water mixture of these compounds. Exposure of dry seeds to a gaseous 100% NF3 atmosphere for 1 to 8 hours caused inhibition of subsequent germination depending on the seed species. Exposure of seeds to a 10% N2F4 atmosphere for 1 hour completely inhibited germination of all five species of seeds. Exposure of dry seeds to less than 500 ppm of either bromine pentafluoride or chlorine trifluoride in air drastically reduced their subsequent germination even when the exposure time was for less than one hour. Exposures of plant seedlings to gaseous ClF3 in air at 500 and 2,000 ppm for 5 minutes resulted in extensive destruction of the plants; bromine pentafluoride-air mixtures were even more damaging than ClF3 atmospheres. Concentrations of N2F4 or NF3 up to 10,000 ppm in air were required to cause visible damage of plant seedlings after a 30 to 60 minute exposure period. Plant injury was caused by irrigation of plant seedlings with solutions formed by the reaction of ClF3 or BrF5 with water. The exposed seeds and seedlings were analyzed for fluoride content. The equipment and methods used for these exposures is described.

Book Synopsis Metabolism and Pharmacology of Inorganic and Fluorine Containing Compounds by : Frank N. Dost
Download or read book Metabolism and Pharmacology of Inorganic and Fluorine Containing Compounds written by Frank N. Dost and published by . This book was released on 1968 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies have been made of the toxicology and chemistry of nitrogen trifluoride, tetrafluorohydrazine, chlorine trifluoride, bromine pentafluoride, and oxygen difluoride. Lethality of each agent by inhalation has been determined, as well as estimates of lethality after intraperitoneal administration. Experimental evidence suggests that the lethal effect of interhalogens is by corrosive local destruction of pulmonary surfaces, resulting in failure of gas exchange. Oxygen difluoride is thought to pass intact into the pulmonary cells where it reacts with biochemical reducing systems to ultimately cause cell death and structural failure. The nitrogen fluorides both cause intrinsically lethal levels of methemoglobin formation, but other pharmacologic activity by these compounds or their derivatives may also contribute to their toxic activity.

Download or read book Ignition! written by John Drury Clark and published by Rutgers University Press. This book was released on 2018-05-23 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: This newly reissued debut book in the Rutgers University Press Classics Imprint is the story of the search for a rocket propellant which could be trusted to take man into space. This search was a hazardous enterprise carried out by rival labs who worked against the known laws of nature, with no guarantee of success or safety. Acclaimed scientist and sci-fi author John Drury Clark writes with irreverent and eyewitness immediacy about the development of the explosive fuels strong enough to negate the relentless restraints of gravity. The resulting volume is as much a memoir as a work of history, sharing a behind-the-scenes view of an enterprise which eventually took men to the moon, missiles to the planets, and satellites to outer space. A classic work in the history of science, and described as “a good book on rocket stuff…that’s a really fun one” by SpaceX founder Elon Musk, readers will want to get their hands on this influential classic, available for the first time in decades.
