In 1849, the French chemists Jean-François Persoz and Bloch, and the German chemist Peter Kremers (1827-?), independently first synthesized thionyl chloride by reacting phosphorus pentachloride with sulfur dioxide. However, their products were impure: both Persoz and Kremers claimed that thionyl chloride contained phosphorus, and Kremers recorded its boiling point as 100 °C (instead of 74.6 °C). In 1857, the German-Italian chemist Hugo Schiff subjected crude thionyl …
