| titleOfInvention | METHOD FOR PRODUCING MAGNETIC LIQUID |
| abstract | 1. A method of obtaining a magnetic fluid, including obtaining highly dispersed particles of magnetite by chemical coprecipitation, stabilization of the obtained particles of magnetite with the formation of the first chemisorption layer, the subsequent dispersion of stabilized particles of magnetite in low molecular weight alcohols and acetone, characterized in that the stabilization of magnetite particles is carried out by dicarboxylic acid, and the dispersion stabilized particles of magnetite in low molecular weight alcohols and acetone is carried out after treatment with alcohol for the final formation of the protective sheath. ! 2. The method according to claim 1, characterized in that terephthalic, adipic and other high molecular weight dicarboxylic acids with the number of carbon atoms C6-C12 are used as dicarboxylic acid to stabilize the magnetite particles. ! 3. The method according to claim 1, characterized in that as the alcohol introduced for the final formation of the protective shell, use alcohols with the number of carbon atoms C6-C12. |
