    Product Safety Summary Phosphorus Oxychloride CAS No. 10025-87-3 This Product Safety Summary is intended to provide a general overview of the chemical substance. The information in the summary is basic information and is not intended to provide emergency response information, medical information or treatment information. The summary should not be used to provide in-depth safety and health information. In-depth safety and health information can be found in the Safety Data Sheet (SDS) for the chemical substance. Names Phosphorus oxychloride Phosphorus trichloride oxide Phosphoric trichloride POCl 3 Product Overview Solvay Novecare does not sell phosphorus oxychloride directly to consumers. Phosphorus oxychloride (POCl3) is used as a chemical intermediate to produce a variety of products which are used in several applications including manufacture of triarylphosphate esters which are used as flame retardants as well as an intermediate in the production of pharmaceutical, textile and agricultural chemicals. Phosphorus oxychloride is used in industrial applications and other processes where workplace exposures can occur. Consumer exposure does not occur as phosphorus oxychloride is not used in any commercially available product. Phosphorus oxychloride is dangerous to human health. Phosphorus oxychloride may be fatal if inhaled, highly toxic if swallowed, harmful if absorbed through skin and can cause severe burns which may result in scarring. Phosphorus oxychloride is consumed in manufacturing processes. POCl3 can make its way into the environment through unintentional releases (spills). POCl3 will not bioaccumulate but is not biodegradable. POCl3 in higher concentrations can be harmful to aquatic life due to formation of acids from the hydrolysis of POCl3. When released into the atmosphere, phosphorus oxychloride exists as vapor.

OSHA defines these materials as "select" carcinogens, reproductive toxins and acutely toxic materials.

The information in the summary is basic information and is not intended to provide emergency response information, medical information or treatment information. The summary should not be used to provide in-depth safety and health information. In-depth safety and health information can be found in the Safety Data Sheet (SDS) for the chemical substance. Names Phosphorus trichloride Phosphorus (III) chloride Phosphorous chloride PCl 3 Product Overview Solvay Novecare does not sell phosphorus trichloride directly to consumers and phosphorus trichloride has no known uses except as an intermediate to produce other chemicals. Phosphorus trichloride (PCl3) is used as a chemical intermediate to produce a variety of products which are used in several applications including agricultural products, surfactants and metal extractants, flame retardants, additives for lubricants and stabilizers for plastics. Phosphorus trichloride is used in industrial applications and other processes where workplace exposures can occur. Consumer exposure does not occur as phosphorus trichloride is not used in any commercially available product. Phosphorus trichloride is dangerous to human health. Phosphorus trichloride may be fatal if inhaled, highly toxic if swallowed, harmful if absorbed through skin and can cause severe burns which may result in scarring. Phosphorus trichloride is consumed in manufacturing processes. PCl3 can make its way into the environment through unintentional releases (spills). PCl3 will not bioaccumulate but is not biodegradable. Based on ecotoxicological testing performed on fish and fresh-water invertebrates, PCl3 in higher concentrations can be harmful to aquatic life due to formation of acids from the hydrolysis of PCl3.

Tertiary phosphines with heavy grol .pa would be most valuable for this work since phosphorus seems to be better suited to ezhi- bit asymmetry than any other element 01' the fifth group.<24) It is believed that the heavy groups would slow down the oscillations of the phosphorus atom and make possible the resolution of the optical isomers .. However, this work has been retarded by the lack of a convenient means of preparing asymmetrical sub- stituted triaryl phosphines. The usual method of preparing triaryl phosphines is by the reaction of the appropriate phosphenyl chloride with a Grignard reagent.
