18.8 Occurrence, Preparation, and Properties of Phosphorus
Phosphorus trichloride undergoes a variety of redox reactions: 3PCl 3 + 2 CrO 3 → 3POCl 3 + Cr 2 O 3 PCl 3 + SO 3 → POCl 3 + SO 2 3 PCl 3 + SO 2 → 2POCl 3 + PSCl 3 PCl 3 as a nucleophile. Phosphorus trichloride has a lone pair, and therefore can act as a Lewis base, e.g., forming a 1:1 adduct Br 3 B-PCl 3. See more Phosphorus trichloride is an inorganic compound with the chemical formula PCl3. A colorless liquid when pure, it is an important industrial chemical, being used for the manufacture of phosphites and other organophosphorus compounds See more 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. Later during the same year, the English chemist Humphry Davy produced … See more It has a trigonal pyramidal shape. Its P NMR spectrum exhibits a singlet around +220 ppm with reference to a phosphoric acid standard. See more PCl3 is important indirectly as a precursor to PCl5, POCl3 and PSCl3, which are used in many applications, including herbicides, insecticides See more World production exceeds one-third of a million tonnes. Phosphorus trichloride is prepared industrially by the reaction of chlorine with white phosphorus, using phosphorus trichloride as the solvent. In this continuous process PCl3 is removed as it is formed in … See more The phosphorus in PCl3 is often considered to have the +3 oxidation state and the chlorine atoms are considered to be in the −1 oxidation state. … See more • 600 ppm is lethal in just a few minutes. • 25 ppm is the US NIOSH "Immediately Dangerous to Life and Health" level • 0.5 ppm is the US OSHA "permissible exposure limit" over a time-weighted average of 8 hours. See more WebA molecule is the smallest part of a substance that has the physical and chemical properties of that substance. In some respects, a molecule is similar to an atom. A molecule, however, is composed of more than one atom. Some elements exist naturally as molecules. For example, hydrogen and oxygen exist as two-atom molecules.
