The Radiation Chemistry of Phosphine-Ammonia Mixtures in the Gas Phase
Radiation Research, 1970Irradiation of gaseous mixtures of ammonia and phosphine with Co-60 gamma rays yields hydrogen, red phosphorus, and nitrogen. Attempts to find other products have been unsuccessful. Hydrogen yields are larger than predicted from the assumption of an "ideal" mixture, in which the ammonia and phosphine decompose proportionately to the dose each absorbs ...

Phosphine Gas Adsorption in a Series of Metal–Organic Frameworks
Inorganic Chemistry, 2015For the first time, phosphine adsorption has been evaluated in a series of metal-organic frameworks (MOFs). Open-metal coordination sites were found to significantly enhance the ability of MOFs to adsorb highly toxic phosphine gas, with the identity of the open-metal site also modulating the amount of gas adsorbed. The MOFs studied outperform activated

PERSISTENCE OF PHOSPHINE GAS IN FUMIGATED IRAQI DATES
Journal of Food Safety, 1984Phosphine gas (PH3) is a widely used fumigant for stored fruits and grains. Previous studies indicated that all residues of this gas are eliminated by normal aeration but the exact time has never been determined.The objective of this work was to determine the time required for desorption of phosphine from fumigated dates relative to aeration time and ...

Gas-chromatographic determination of phosphine in ambient air
The Analyst, 1978Air samples taken in the neighbourhood of a chemical plant manufacturing dicyanamide from calcium carbide, of which process phosphine is a by-product, were collected in polyester bags and brought to the laboratory for analysis. A gas chromatograph equipped with a nitrogen-phosphorus-selective detector was used. The working range was 0.5–5 p.p.b. (parts

A Comparative Study of the Gas-Phase Radiation Chemistry of Phosphine and Ammonia
Radiation Research, 1970Comparison studies of the decomposition in the gas phase of pure phosphine and pure ammonia by cobalt-60 gamma rays show that both compounds are broken down to their elemental constituents. Results of mass balance experiments with pure phosphine indicate that the overall radiolysis reaction is ${\rm PH}_{3}\rightarrow {\rm P}_{\text{red}}+{\textstyle ...

Journal of the Chemical Society, Dalton Transactions, 1972
The i.r. and Raman spectra of difluoro(isocyanato)phosphine, F2PNCO, and difluoro(isothiocyanato)phosphine, F2PNCS, have been recorded. Assignments have been made of all the fundamental frequencies, and normal coordinate analyses have been carried out.

On-site phosphine purification for gas-source MBE of InGaAlP
Journal of Crystal Growth, 1993A gas filter consisting of 150 cm 3 of 3A molecular sieve has been used to purify phosphine immediately prior to in gas-source molecular beam epitaxy. Use of the purified phosphine has been found to reduce the measured electron trap density in n-InGaP and substantially increase the carrier concentration at a given impurity concentration in n-InGaAlP ...

Gas phase ion/molecule reactions in phosphine/methylsilane mixtures
Journal of Organometallic Chemistry, 1996Phosphine/methylsilane mixtures investigated by ion trap mass spectrometry and reaction pathways together with the rate constants of the main reactions are reported. Mechanisms of ion/molecule reactions have been elucidated by single and multiple isolation steps.

Potential of phosphine gas for wood pest control
BIOCHEMICAL AND CELLULAR ARCHIVESWood is primarily attacked by insects, nematodes and fungi, and fumigation remains the main control measure. The major fumigants currently used against wood-boring insect pests are phosphine (PH3), sulfuryl fluoride (SF) and ethanedinitrile (EDN). Among these, PH3 is the most widely used because of its broad global registration. It is applied either in
