R90 is soluble in water but for purification I have used organic separation where I used ethyl acetate, then upon drying this in roto vapour at 60°C at negative pressure I got a viscous honey like liquid, now if I try to dissolve it in water it forms a bead like structure and the whole solution turns cloudy even if i sonicate it didn't work. if I leave this it settles down but the cloudiness stays, can someone explain what should I do to get this problem solved
Yes, it is. After dissolving in water, R90 combines with organic solvents and loses its properties.
Hi, Wasim Abdin. I recommend not adding ethyl acetate.
Chat GPT said "Before trying to dissolve in water, ensure that the ethyl acetate is completely evaporated. Sometimes, even under reduced pressure, residual solvent can remain and cause issues. Try further drying under reduced pressure or at a lower temperature to ensure solvent removal."
