I would like to ask the experts here: what method is used to treat maleic anhydride in the acrylic acid production process? I am extremely grateful to all of you for your help!

Distillation is the only way to separate it; what else can be done?

Maleic anhydride is produced by the dehydration of maleic acid during the purification process, and it remains essentially in the acrylic acid product in the end, without affecting the product quality.

It is discharged as a reconstituted component, so its content in the product is very low

Reply to 4# tomorrow8: What is the content of maleic anhydride in the reconstituted fraction? What are the other ingredients?
