Title:
微細化された安定な固体ディスパージョンを製造するための方法
Document Type and Number:
Japanese Patent JP4280510
Kind Code:
B2
Abstract:
The production of a finely divided stable dispersion of solids having an average particle size of 10 nm to 10 microns comprises injecting at least two streams of a pre-dispersion via high pressure pumps through a nozzle into a reactor chamber enclosing a reactor housing, introducing water vapor into the reactor chamber via an opening so that a vapor atmosphere mainly consisting of water vapor is produced in the chamber, and removing the finely dispersion and vapor and/or partially condensed vapor consisting mainly of water on the gas inlet side from the reactor chamber. An Independent claim is also included for a device for carrying out the process. Preferred Features: The pre-dispersion comprises water or organic compounds as the liquid phase. The pre-dispersion contains a dispersing agent and/or surface-active substances. The water vapor has a temperature of the boiling temperature of water at the pressure prevailing on the gas inlet side.
