Phosphorous trichloride is a popular chemical compound that is majorly used in the production of organophosphorus substance for chemical industries. The PCl3 solvent where the bulk process takes place is made by reacting chlorine with phosphorus directly, and then more phosphorus is added, followed by … Phosphorus trichloride is produced directly from phosphorus and chlorine. POCl 3 is a commonly used dehydrating agent in chemical laboratories. Phosphorus Chemistry in Everyday Living 2nd ed Toy ADF, Walsh EN; Phosphorus Chemistry in Everyday Living 2nd ed p.221 (1987). Toy ADF, Walsh EN; Phosphorus Chemistry in Everyday Living 2nd ed p.221 (1987). How to answer the questions below? The entire range of this reactive chemical is formulated using premium … Phosphorus trichloride (PCl 3) is a toxic and highly reactive reagent, which, on hydrolysis generates phosphorous acid (H 3 PO 3) and hydrochloric acid, exothermically. Thanks to the production technology used, it is characterised by high purity, with, amongst other things, a very low content of impurities in the form of phosphorus compounds at the fifth degree of oxidation (i.e., phosphorus oxychloride). It is used to treat polypropylene before drying in the manufacture of knitted fabrics. It is one of the most important phosphorus chlorides, others being PCl 3 and POCl 3. Other .
