Solvent treatment where distillation is not suitable can be carried out using molecular sieve membranes
Thread Content
In actual solvent treatment, we encounter problems such as solvent azeotropy and the removal of trace impurities from the solvent. You might consider using complex distillation for this purpose, but in some cases, using molecular sieve membranes can bring you some pleasant surprises. Regardless of the dehydration using conventional solvents such as ethanol and dioxane, it applies to the dehydration of formic acid and acetic acid as well. **Removal of trace methanol and ethanol from furan ； It can be reduced to below 300 ppm, or even lower – you wouldn’t have guessed that.
Boss, what type of molecular membrane should be used for formic acid dehydration?
