Material of chloroacetyl chloride distillation tower
Thread Content
In a recent project, there was a distillation tower used to remove chloroacetyl chloride. It has been found that chloroacetyl chloride does not cause much corrosion to stainless steel when there is no water or oxygen present. The current operating conditions also involve the absence of water and oxygen. However, the design firm recommended using a glass-lined tower. Has anyone used such a tower before? Is stainless steel really suitable for this purpose?
Chloroacetic acid project? When the pressure is low, it’s best to use glass-lined materials; after all, chloroacetyl decomposes large amounts of CL-, which causes severe corrosion of stainless steel!
When the temperature is below 200 degrees, the equipment can be lined with PTFE.
Epoxy coating is traditionally used, which limits the production capacity of the devices; it has many defects, is prone to cracking, and is heavy.
