General Description
Clear colorless liquid.
Reactivity Profile
PHENYL PHOSPHINE(638-21-1) is a reducing agent. They slowly generate flammable or noxious gases in contact with water. Phosphides react quickly upon contact with moisture or acids to give the very toxic gas phosphine; phosphides also can react vigorously with oxidizing materials. In general, materials in this group are incompatible with oxidizers such as atmospheric oxygen. They are violently incompatible with acids, particularly oxidizing acids.
Air & Water Reactions
Pyrophoric in air. Insoluble in water. Slowly generates flammable or noxious gases in contact with water.
Potential Exposure
Polyphosphinate is used as an intermediate or a chemical reagent. Polyphosphinate compounds are used as catalysts and antioxidants disproportionate, when heated to give phosphonic acid derivatives plus PF.
Fire Hazard
Flash point data are not available for this chemical, but PHENYL PHOSPHINE is probably combustible.
First aid
Eyes: first check the victim for contact lenses and remove if present. Flush victim’s eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim’s eyes without specific instructions from a physician. Immediately transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop. Skin: immediately flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. Immediately call a hospital or poison control center even if no symptoms (such as redness or irritation) develop. Immediately transport the victim to a hospital for treatment after washing the affected areas. Inhalation: immediately leave the contaminated area; take deep breaths of fresh air. Immediately call a physician and be prepared to transport the victim to a hospital even if no symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, SCBA should be used; if not available, use a level of protection greater than or equal to that advised under protective clothing. Ingestion: if the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and immediately call a hospital or poison control center. Generally, the induction of vomiting is not recommended outside of a physician’s care due to the risk of aspirating the chemical into the victim’s lungs. However, if the victim is conscious and not convulsing and if medical help is not readily available, consider the risk of inducing vomiting because of the high toxicity of the chemical ingested. Ipecac syrup or salt water may be used in such an emergency. Immediately transport the victim to a hospital. If the victim is convulsing or unconscious, do not give anything by mouth, ensure that the victim’s airway is open and lay the victim on his/her side with the head lower than the body. Do not induce vomiting. Immediately transport the victim to a hospital.
Shipping
UN2845 Pyrophoric liquids, organic, n.o.s Hazard Class: 4.2, Labels: 4.2-Spontaneously combustible material. Technical Name Required. Note: this chemical is also a strong reducing agent.
Incompatibilities
A strong reducing agent. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Water reactive; spontaneously combustible in high concentrations in moist air. Potential exposure to gaseous phenylphosphine and phosphorus oxides when heated above 200C. Organophosphates are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrideds and active metals. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides.
Chemical Properties
Phenylphosphine is a clear, colorless liquid. Foul odor.
Uses
Exposure to phenylphosphine may occur when phenylphosphinates
(used as catalysts and antioxidants) are heated
above 200°C, yielding phenylphosphonic acid
derivatives and phenylphosphine.
Uses
It is mainly used as a precursor to other organophosphorus compounds. It can function as a?ligand?in coordination chemistry. Phenylphosphine also have uses in polymer synthesis.
Health Hazard
Phenylphosphine is a respiratory and skin irritant; multiple exposures in
rodents causes hematologic changes and testicular degeneration in males.
