METHOD OF PREPARING CARRIER LIQUIDS |
摘要 |
The invention provides a method for the preparation of a carrier liquid which comprises the steps of: (I) preparing an emulsion comprising: a) an aqueous phase, b) A second liquid phase which is volatile and which is immiscible with aqueous phase (a), c) A carrier material which is soluble in the continuous phase of the emulsion and which is liquid at ambient temperature, and d) A dopant which is soluble in the disperse phase of the emulsion, (II) cooling the emulsion produced in step (I) to a temperature at which at least both the continuous phase and the carrier material become solid, (III) removing water and the volatile second phase from the cooled emulsion in vapor form, and, (IV) returning the product of step (III) to ambient temperature to obtain a liquid product with the dopant dispersed therein. |
