Please optimize the molar ratio, Temp for the reaction and water content.

• Incorrect Molar Ratio: The components of the DES might not be in the correct molar ratio, leading to phase separation and crystallization.
• Temperature: The mixture might not have been heated to the appropriate temperature to ensure complete dissolution of the components.
• Water Content: Excess water or impurities in the mixture can affect the formation of the DES, causing it to crystallize instead of forming a homogenous solution
