Phosgene was first deployed as a chemical weapon by the French in 1915 in World War I. [24] It was also used in a mixture with an equal volume of chlorine, with the chlorine helping to spread the denser phosgene. [25] [26] Phosgene was more potent than chlorine, though some symptoms took 24 hours or more to manifest.
Phosphine (IUPAC name: phosphane) is a colorless, flammable, highly toxic compound with the chemical formula P H 3, classed as a pnictogen hydride.Pure phosphine is odorless, but technical grade samples have a highly unpleasant odor like rotting fish, due to the presence of substituted phosphine and diphosphane (P 2 H 4).
The toxicity of aluminium phosphide is attributed to the liberation of phosphine gas, a cytotoxic compound that causes free radical mediated injury, inhibits vital cellular enzymes and is directly corrosive to tissues. The following reaction releases phosphine when AlP reacts with water in the body: AlP + 3 H 2 O → Al(OH) 3 + PH 3, and
The Mayo Clinic diet was created by weight management practitioners at the Mayo Clinic and was designed as a lifestyle change program to promote gradual and sustained weight loss, says Melissa ...
Higher levels of omega-6 fatty acids often found in ultraprocessed foods may interfere with the immune system’s fight against cancer cells, a new study says.
Tributylphosphine is the organophosphorus compound with the chemical formula P(CH 2 CH 2 CH 2 CH 3) 3, often abbreviated as PBu 3. It is a tertiary phosphine. It is an oily liquid at room temperature, with a nauseating odor. It reacts slowly with atmospheric oxygen, and rapidly with other oxidizing agents, to give tributylphosphine oxide.
Starting a blog helped me document my experience and find solace. When I was diagnosed, I couldn’t find any information about some of the ins and outs of going through cancer treatment, beyond ...
Organophosphines are organophosphorus compounds with the formula PR n H 3−n, where R is an organic substituent.These compounds can be classified according to the value of n: primary phosphines (n = 1), secondary phosphines (n = 2), tertiary phosphines (n = 3).
