Chemical properties of phosphine
Phosphine, or what is called
hydrogen phosphide, is considered a very toxic gas. It is colorless and
flammable. It has an odor similar to the strong, unbearable smell of garlic, in
addition to having a structural formula similar to the structural formula of
ammonia; However, it is considered a weak solvent and also does not dissolve
well in water, and phosphine is formed as a result of the interaction of white
phosphorus with a strong base or with hot water, or as a result of the
interaction of water with calcium phosphide, and when phosphine bonds with
other organic compounds, it is called phosphine derivatives, where it is
possible One of the bonds with hydrogen atoms is replaced by one of these
groups, and single, double or triple bonds can be formed, and the resulting
compound is called by adding the first syllable of the compound that was
attached to it, and in the case of mineral salts linking, the resulting
compounds are called phosphide compounds, and when hydrogen atoms are
connected, the products are called compounds phosphonium;
Phosphine's Health Effects
When exposed to phosphine, some
health problems will result, including:
1. Exposure to phosphine gas results in respiratory,
nervous, and digestive problems as well.
2. The resulting symptoms may include headache and
dizziness, fatigue and drowsiness, a feeling of burning in the bronchi, nausea
and vomiting, a feeling of discomfort in the digestive system, coughing with
green phlegm, difficulty breathing and chest tightness, and others.
3. Continuous exposure to phosphine may cause weight loss
and effects on the liver and kidneys.
4. There is no evidence that phosphine is a carcinogen.
Expected dangers when using phosphine
Among the risks expected when
dealing with phosphine are the following:
· Exposing phosphine to heat or combustion produces
toxic fumes.
· Phosphine is a highly explosive substance. The
explosion may occur when interacting with air, heating the containers in which
it is stored, or rupturing the cylinders in which it is placed.
