I aim to synthesize a deep eutectic solvent using a 1:2 ratio of choline chloride to diethylene glycol through a heating method to achieve a homogeneous solvent. However, after 24 hours, crystals formed in the solvent. Please suggest a solution to this issue.
Dear Reza Daneshfar, it is the most studied combination among DES systems, with the ratio you mentionned. Have you done any literature search ? Or you are looking for something special ? My Regards
It precipitated exactly in the ratio I intended. Could you advise me on how to adjust the conditions of time, temperature, and stirring to prevent precipitation? Thank you for guiding me on the precise steps to take.
Most probably it is due to high water content. Get rid of it from your components prior to mixing.
I am confident that they are dry. Please advise me on stirring time, temperature, and preparation conditions. Thank you.
