On the purification of aqueous fluorobenzene
Thread Content
Hello everyone, is there anyone who has experience in the purification of fluorobenzene? I have finished fluorobenzene here, and I need to reduce the moisture content from around 200 ppm to less than 20 ppm. Can conventional distillation be used to remove the moisture to meet the quality requirements? Since I don’t have the appropriate experimental equipment, it’s not possible to conduct tests at the moment; theoretically, it’s not clear whether this approach will work or not. If it passes through the molecular sieve directly, will that meet the requirements? What about the cost? I would appreciate some guidance from those who are more experienced.
Under reduced pressure distillation, part of the mixture of fluorobenzene and water is removed, leaving in the distillation flask the desired high-quality product.
Using 4A molecular sieve should enable meeting the 20 ppm requirement, with low production costs; the equipment investment depends on the processing volume
Do you produce fluorobenzene or use it? You can contact them via email at 2319369792@qq.com
Add alkali solution to absorb water, stir, and then separate the alkali
He already has 200 pp – how can it still be washed? Wash it, and it might reach 1000 ppm
