    摘要: The invention relates to a process for the preparation of finely divided suspensions by melt emulsification, comprising at least one substance with a melting temperature above room temperature, comprising the following steps:(a) passing at least one preemulsion, comprising one continuous phase and one disperse phase, to a rotor-stator machine, a rotor-rotor machine or to a continuous and/or disperse phase;(b) optionally adding one or more further components to the at least one preemulsion in the rotor-stator machine;(c) emulsifying the at least one preemulsion with mechanical shear and/or elongation and/or turbulence at a temperature which is at most 10 K above the melting temperature of the at least one substance with a melting temperature above room temperature, or at a temperature which is at least 10 K below and at most 10 K above the glass transition temperature or the melting temperature, if the substance with a melting temperature above room temperature is a polymer, for producing a finely divided emulsion;(d) cooling the finely divided emulsion to produce a finely divided suspension;where the disperse phase fraction at least in step (c) is in the range from 85% to 99.5%.
