Abstract
PURPOSE: Paradichlorobenzene, useful as vermicide or deodorant, is melt dispersed into water and solidified by cooling the dispersion as it is to form ball particles of crystals, thus improving the operability on processing.
CONSTITUTION: Paradichlorobenzene, 1 volume, is added to 0.5W5 volumes of water containing 0.002W0.1 wt% of a p-dichlorobenzene dispersant and kept in the temperature range from 55 to 80°C under stirring. Thus, the dichlorobenzene is dispersed in hot water as molten particles, then they are rapidly cooled below 31°C and solidified in the shape of molten particles. The solid particles are washed with water, separated, and dried to obtain the fine balls of dichlorobenzene crystals, not conventional flakes.
