The company needs to purchase pumps for producing thionyl chloride; it’s not clear what material should be used
Thread Content
The company needs to purchase a pump for chlorosulfuryl chloride handling; the temperature is around 150 degrees, with occasional spikes to 200 degrees. Will a stainless steel pump work?
Don’t do it occasionally; if the temperature can be kept below 170 degrees, fluorine-lined pumps can be used. 200 degrees won’t work.
Thionyl chloride has a boiling point of 78.8°C; when heated to about 140°C, it decomposes into chlorine, sulfur dioxide, and sulfur monoxide. The temperature is around 150 degrees, occasionally dropping to 200 degrees? What's going on?

Our company also uses this; the conditions are similar
