Seek advice on concentrating dilute acetic acid? A 30% acetic acid solution is produced as a by-product, which needs to be concentrated to around 70%. Is there any way? Can ordinary distillation be used? ?
A 30% acetic acid solution is concentrated to around 70%; ordinary distillation can be used, with a graphite condenser for condensation.
Distillation can be used; extraction is needed if a higher concentration is required.
This concentration can be achieved through ordinary distillation; if higher precision is required, azeotropic distillation is needed. Butyl acetate can be used as an azeotrope
An enamel-coated patch condenser can also be used for distillation.
What products are produced that result in acetic acid as a by-product?
Just react it directly with soda ash to produce liquid sodium acetate.
