Equipment for producing epichlorohydrin by the glycerol method
Thread Content
Currently, yellow solids are always formed at the bottom of the dehydration tower in the unit. I am seeking to understand the reason for this; does the ECH unit experience the same issue? I would appreciate it if you could share the reasons behind it as well as any measures that can be taken to address it.
It would be best if you had detailed photos to analyze the reasons and solve this problem
Due to the company’s computers, it’s difficult to upload the photos; they show yellowish, red-colored granular solids. There are solids at the bottom of the dehydration tower as well as at the top; it is said to be a polycondensation product of acraldehyde, so I have always suspected that this is also a polycondensation product of acraldehyde. However, not only acraldehyde is involved – chloral, which is produced by the hydrolysis of epichlorohydrin, must also be part of it
