Definition of phosphine in English:

phosphine

noun ˈfɒsfiːnˈfɑsfin

mass nounChemistry

A colourless foul-smelling gaseous compound of phosphorus and hydrogen, analogous to ammonia.
Chemical formula: PH₃. It forms salts containing the phosphonium ion, PH₄⁺
Example sentencesExamples
- Since the explosion yesterday morning, which jammed a main cargo door shut, gases including hydrogen, phosphine and arsine, a derivative of arsenic, have started venting from the cargo hold.
- The two main alternatives for methyl bromide in pesticides are ‘integrated commodity management’ and fumigation, which uses phosphine and carbon dioxide to kill the pests.
- The suspected gasses in the SIDS deaths were; arsine from arsenic, phosphine from phosphorus, and stibine from the element antimony.
- The inorganic compound phosphine is very similar to ammonia in its substitution reactions.
- It is believed Sir Derek took aluminium phosphide, which creates the toxic gas phosphine when it comes into contact with moisture.

Origin

Late 19th century: from phospho- 'relating to phosphorus' + -ine⁴, on the pattern of amine.
