Separation of methanol and toluene
Thread Content
The materials in question are methanol and toluene, which contain about 20% toluene. Methanol is required to be 99.9% and toluene 99.9%. The extraction effect using water is not ideal. The product concentration cannot reach methanol and toluene, which is prone to azeotropic distillation. The effect is not very good. Do you have any good ideas? Please give me some advice.
Just wash with 20% sodium chloride aqueous solution.
Thank you. I wonder if you have any application examples? How is the effect of washing with 20% sodium chloride aqueous solution to extract toluene? Can the purity be achieved?
I think this can be verified by doing a small test, and it is not difficult.
Is it not difficult? I don’t know if the purity can be achieved. Is there a better way? Has anyone encountered it? This post was last edited by vrain on 2009-2-26 14:53 ]
