Refining and purifying diisopropyl ether
Thread Content
Diisopropyl ether contains about 3% each of 2-methyl-2-pentene and 3-methyl-2-pentene. Its boiling point is very close to that of diisopropyl ether; the mixture also contains trace amounts of water and isopropanol. It’s difficult to separate these components, making it hard to obtain diisopropyl ether with a purity of over 99%. What good solutions does anyone have? Please give me some advice; thanks!
Have you tried evacuating it? If nothing else works, distillation extraction is the only option
I haven’t tried vacuum extraction; its boiling point is already not high, and vacuum conditions would require chilled water as well. The key issue with extraction is finding an appropriate solvent. I searched online for solvents suitable for separating benzene from cyclohexane, and I tried them in software, but it was still not possible to separate diisopropyl ether from the impurities. It’s hard!
We can provide isopropyl ether with a purity of 99.7% directly; if you need it, please contact me at 15061735421
