Phosphorus trichloride (phosphorus chloride, PCl3) is a colorless fuming liquid that reacts violently with water to liberate phosphoric acid and hydrogen chloride (HCL) gas. In the laboratory it may be more convenient to use the less toxic red phosphorus. Dispose as hazardous waste. Most of its reactivity is consistent with this description. Symptoms may include burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea and vomiting. Alcohols such as ethanol react similarly in the presence of a base such as a tertiary amine:[6], In the absence of base, however, the reaction proceeds with the following stoichiometry to give diethylphosphite:[7][8]. For example, bis(diethylamino)chlorophosphine, (Et2N)2PCl, is obtained from diethylamine and PCl3. Fire: Use Class D extinguisher, such as Met-L-X or smother the fire with dry sand. Phosphorus oxychloride hydrolyzes rapidly in water at room temperature (1), and therefore will not volatilize from water or moist soil surfaces (SRC). The chemical formula is PCl3. The impact of variables on reaction rates including the interface surface area, layer depth, and stirring were investigated experimentally. Secondary amines (R2NH) form aminophosphines.

Show a balanced equation, including states, for the reaction between phosphorus trichloride and water. phosphorus pentachloride it quickly turns red solid. [4] Phosphorus trichloride is prepared industrially by the reaction of chlorine with a refluxing solution of white phosphorus in phosphorus trichloride, with continuous removal of PCl3 as it is formed (in order to avoid the formation of PCl5). Eye Contact: Causes severe burnes with local pain and blurred vision. [11], Phosphorus trichloride was first prepared in 1808 by the French chemists Joseph Louis Gay-Lussac and Louis Jacques Thénard by heating calomel (Hg2Cl2) with phosphorus. Seek medical attention as needed. Thiols (RSH) form P(SR)3. Spills: Control all sources of moisture. Skin Contact: Causes severe burnes with local pain and redness. Irreversible damage can occur from vapors and liquid contact. Do not heat PCl3 without proper containment for generated hydrochloric and phosphoric acid vapors. Phosphorus trichloride reacts spontaneously with moisture to form hydrochloric acid (cloud) and phosphorous acid. The product is soluble in benzene, carbon disulphide and carbon tetrachloride. The phosphorus is considered to be in a 3+ oxidation state and each chlorine is considered to be in a 1- oxidation state. Wear safety glasses, impervious gloves and a fire-retardant laboratory coat. It is used to convert primary and secondary alcohols into alkyl chlorides, or carboxylic acids into acyl chlorides, although thionyl chloride generally gives better yields than PCl3. Scoop spilled materials with spark-resistant tools and place in a container for disposal. When in contact, water and phosphorus trichloride will form two liquid layers with a reaction starting at the interface. The reaction of PCl3 with Grignard reagents and organolithium reagents is a useful method for the preparation of organic phosphines with the formula R3P (sometimes called phosphanes) such as triphenylphosphine, Ph3P. Based on a scenario where the chemical is spilled into an excess of water (at least 5 fold excess of water), half of the maximum theoretical yield of Hydrogen Chloride (hydrochloric acid) gas will be created in 0.12 minutes. A step-by-step explanation of how to draw the PCl3 Lewis Structure (Phosphorus Trichloride). Inhalation: Extremely destructive to tissues of the mucous membranes and upper respiratory tract. The chemical reaction is given below. [16] Later during the same year, the English chemist Humphry Davy produced phosphorus trichloride by burning phosphorus in chlorine gas. These compounds do not usually contain the chlorine atoms found in PCl3. It is found mainly in your bones and teeth. Keep a supply of dry sand available in the work area and ensure there is a Class D extinguisher immediately available. Avoid contact with water and humid environments.
