Selection of materials for alkaline substances
Thread Content
Our company uses trichloropropane to react with 32% liquid caustic soda. Experts, may I ask what type of reactor material should be used? Thank you. The temperature is around 80 degrees. At atmospheric pressure.
Choosing a nickel-based one might be more durable!
The company’s design calls for the use of enamel-lined reaction vessels; I’m not sure what their lifespan is
If trichloropropane can ionize to release chloride ions, stainless steel cannot be used. If the final pH value. With proper temperature control, glass-lined equipment can be used. Glass-lined reactors in which alkali solutions are involved in the reaction are widely used. It depends on the pH value and temperature. The inlet of the alkali solution pipe is given special treatment.
Enameled surfaces are not resistant to alkalis; do not use enamel
What is the temperature? If it’s high, use nickel-lined or nickel-based alloys; Inconel 690 performs well in terms of resistance to alkalis and high temperatures, though it is relatively expensive
80 degrees Celsius – isn’t steel-lined PTFE great?
