MICROCAPSULES WITH WATER OR WATER SOLUTION (VERSIONS) AND METHOD OF THEIR PRODUCTION (VERSIONS) Russian patent published in 2011 - IPC B01J13/02 A61J3/07 A01N25/28 

FIELD: process engineering.

SUBSTANCE: invention maybe used for efficient fire extinguishing, fast cooling of overheated structures and production of lower-flammability compounds. Microcapsules have a micro-sphere-like core containing water or water solution in gel state, main shell around said core to provide for core stable shape and composition and rule out water evaporation therefrom the core, and, additionally, comprises outer shell with lyophilic properties. Versions of proposed methods comprises producing aforesaid core via interaction of appropriate initial water solutions to be placed in microsphere and containing appropriate components of the shell with components of solutions to be precipitated and used for producing and cross-linking of gel, and producing additional lyophilic shell via interaction of components of initial solutions with appropriate components in organic medium.

EFFECT: high efficiency in fire extinguishing or fast cooling of overheated structures.
