Preparation of Phosphorus pentachloride: PCl₅ is prepared by the chlorination of PCl₃. This reaction was used to produce ca. 10,000,000 kg of PCl₅ in 2000. PCl₅ exists in equilibrium with PCl₃ and chlorine, and at 180 °C the degree of dissociation is ca. 40%. Because of this equilibrium, samples of PCl₅ often contain chlorine, which imparts a greenish colouration.

Uses of Phosphorus pentachloride: In its most characteristic reaction, PCl₅ react upon contact with water to release hydrogen chloride and give phosphorus oxides. PCl₅ is most often used for chlorinations of organic and inorganic compounds. The first hydrolysis product is phosphorus oxychloride:

PCl₅ + H₂O → POCl₃ + 2 HCl

When you are using this chemical, please be cautious about it as the following:
This chemical is very toxic. It is harmful if swallowed and is very toxic by inhalation. In addition, it can cause burns. In case of contact with eyes, you should rinse immediately with plenty of water and seek medical advice. Whenever you will contact it, please wear suitable protective clothing, gloves and eye/face protection. In case of accident or if you feel unwell seek medical advice immediately (show the label where possible).

You can still convert the following datas into molecular structure:
