摘要
A process for removing contaminating solvents from solutions containing solid solutes comprising contacting a co-solvent that forms an azeotrope with the contaminating solvent forming a mixture thereby and spray drying the contaminating solvent co-solvent mixture in the presence of the co-solvent at a temperature equal to or above the temperature where the azeotrope distills whereby the contaminating solvent has been azeotropically distilled away from the solute. The process is particularly useful for polymeric solutes, especially silicones.
