Phosphine

The only gas I can think of is poisonous phosphine which is not especially stable. ❋ Unknown (2010)

Titan life's metabolism might involve chemical compounds such as phosphine and hydrogen sulfide, which are both foul-smelling gases that are toxic to humans. ❋ Unknown (2010)

India exports corn fumigated with aluminium phosphine, considered milder than methyl bromide, across Asia; no other Asian countries have complained of pests. ❋ Sameer Mohindru (2011)

The dragons, named for the mythical Terran beast they resembled, had two valuable characteristics: They could instantaneously travel from one place to another, and after chewing a phosphine, bearing rock, they could emit a flaming gas. ❋ Christian Bell (2010)

I discovered turned out to be quite useful for asymmetric hydrogenation, at least those that contained the appropriate enantiomerically pure phosphine ligand. ❋ Unknown (2006)

Methyl bromide which is currently being replaced by phosphine for the fumigation of stored cocoa beans has been identified as an ozone-depleting substance. ❋ Unknown (2007)

The resourceful colonists fought back with the last of their space-going technology while devising a series of long-term, biological defenses, chief among them, fire-breathing dragons that chewed phosphine-bearing rocks -- firestone -- to create their flames. ❋ McCaffrey, Anne (2006)

Children in the home may be injured by direct contact with caustic materials such as lye and hydrochloric acid, solvents such as acetone and ether, or toxic gases such as ammonia vapors and phosphine gas. ❋ Unknown (2006)

The phosphine first used by Knowles was not enantiomerally pure, yet it produced a mixture in which there was ❋ Unknown (2001)

Knowles exchanged the non-chiral phosphine triphenylphosphine in A to the chiral phosphine B and obtained a catalyst for asymmetric hydrogenation. ❋ Unknown (2001)

(A) was replaced by one of the enantiomers of a chiral phosphine. ❋ Unknown (2001)

A professional exterminator fumigates the stack with phosphine. ❋ Unknown (1998)

Wear a full face mask with a new type AX breathing filter (brown coloured ring)! in contrast to working with phosphine, this mask must definitely be worn in any case on applying methyl bromide. ❋ Unknown (1996)

This limits the possibilities of application of phosphine severely. ❋ Unknown (1996)

· For phosphine, only use type B filters with a grey coloured label, ❋ Unknown (1996)

As far as phosphine is concerned, new methods of application may contribute to a reduction of the quantities required for treatment and improve its performance Among the technologies which have been developed, mixtures with CO?, combination with heat or the constant flow system which improves gas distribution seem promising. ❋ Unknown (1996)

The same criteria for sealing apply as for phosphine described in section 9.2.1 5. ❋ Unknown (1996)

Poor fumigation practices have, however, led to resistance against phosphine to alarming proportions world-wide, and the tendency is increasing. ❋ Unknown (1996)

As there is a danger of self-ignition with large concentrations of phosphine, tablets and pellets should not touch each other. ❋ Unknown (1996)

Recent improvements led to a product with delayed decomposition packed in bags made of polyethylene fleece, which is permeable to water vapour and phosphine, but resistant to liquid water, ❋ Unknown (1996)
