CRYSTALLIZATION FROM OIL-IN-WATER EMULSIONS - PARTICLE SYNTHESIS AND PURIFICATION OF MOLECULAR MATERIALS

The use of emulsions as a means of studying the kinetics of homogeneou s nucleation has been well known for a number of years. In this contri bution, however, attention is given to the possible use of emulsions i n novel process technology, on the one hand as a means of directing th e size and morphology of particulate materials and on the other as the basis for melt purification. m-Chloronitrobenzene serves as a model c ompound in this work, although the central concepts are valid for any low melting molecular material. Particular attention has been paid to the choice and mode of action of the emulsifier since it is this which ultimately controls the outcome of the crystallization process.
