Seeking advice on the corrosiveness of dichloroethane
Thread Content
What are the corrosive properties of dichloroethane and carbon tetrachloride, and with which organic substances are they miscible?
It’s mainly mixed with inorganic acids and bases; how can anti-corrosion measures be taken?

For materials resistant to corrosion by dichloroethane and carbon tetrachloride, impermeable graphite is the best choice, such as graphite heat exchangers, graphite towers, graphite falling film absorbers, graphite reactors, graphite condensers, etc. - -
The key is the situation of mixing it with alkalis; using titanium material is the best choice.
Previously, epoxy coating was used for anti-corrosion on the equipment, but the results were not good
Temperature is provided, and perfluorinated anti-corrosion materials can be selected.
Is the poster asking about the internal anti-corrosion of the equipment or its external anti-corrosion? The anti-corrosion PTFE inside the equipment is pretty good. There are other options as well.
I’m not quite sure what you want to ask Pure carbon tetrachloride and dichloroethane have very weak corrosivity. Are inorganic acids mentioned again below?
Carbon tetrachloride, dichloroethane, as well as toluene, hydrofluoric acid, etc
For temperatures below 100 degrees, fluoroplastics are used; if resistance to temperatures up to 120 degrees is required, fluoroplastic alloys are needed, and there is also a type that can withstand temperatures of 140 degrees!

Graphite materials can be used to manufacture pipelines, heat exchangers, reactors, tower equipment, custom-made devices, pressure vessels, and more.
