Preparation of Thionyl chloride:
The main industrial synthesis involves the reaction of sulfur trioxide and sulfur dichloride:
                         SO3 + SCl2 → SOCl2 + SO2
it also can syntheses from phosphorus pentachloride or chlorine:
                         SO2 + PCl5 → SOCl2 + POCl3
                         SO2 + Cl2 + SCl2 → 2 SOCl2
                         SO3 + Cl2 + 2 SCl2 → 3 SOCl2
The first of the above three reactions also affords phosphorus oxychloride (phosphoryl chloride), which resembles thionyl chloride in many of its reactions.

Uses of Thionyl chloride:
Thionyl chloride is mainly used in the industrial production of organochlorine compounds, which are often intermediates in pharmaceuticals and agrichemicals. It is used to convert carboxylic acids to acyl chlorides and alcohols to the corresponding alkyl chlorides via an internal nucleophilic substitution.It is a component of lithium-thionyl chloride batteries, where it forms the anode with lithium as the cathode. In military usage, thionyl chloride is used in the "di-di" method of producing G-series nerve agents.

Safety Information of Thionyl chloride:
The Thionyl chloride is harmful by inhalation, in contact with skin and if swallowed.And it Causes severe burns. But there is limited evidence of a carcinogenic effect. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. When you use it wear suitable protective clothing, gloves and eye/face protection. After contact with skin, wash immediately with plenty of soap-suds.In case of accident or if you feel unwell, seek medical advice immediately (show the label whenever possible.)Take off immediately all contaminated clothing.
