Material selection for cyanoacetic acid storage tanks
Thread Content
Are there any sister companies that handle the storage of cyanoacetic acid? What materials are used for the storage tanks and pipelines?
Refer to the corrosion data manual for reference
I looked for the corrosion manual but couldn’t find it. . .
What about pressure? Will plastic work? PE?PP?
It can also be lined with steel, PTFE, or enamel.
Cyanoacetic acid is corrosive to stainless steel. Since cyanide is a strong electron-withdrawing group, cyanoacetic acid is more acidic than acetic acid, and the carboxylate ion also has chelating properties. Therefore, cyanoacetic acid causes relatively severe corrosion to stainless steel, and stainless steel equipment cannot be used to store it. From the internet
I can provide you with a polyaniline-coated carbon steel sample; it should be able to withstand the conditions. If that’s possible, using a carbon steel tank would work as well, which could save a lot of money
