EMULSIFYING DISPERSANTS, METHOD FOR EMUSIFICATION AND DISPERSION WITH THE SAME, EMULSIONS, AND EMULSION FUELS

摘要

The invention provides an emulsification technique which permits the formation of functional oil/water or functional granules/water emulsion systems excellent in thermal stability and long-term stability and which can attain the emulsification and dispersion of functional oil or functional granules independent of Erforderlich HLB of the oil or surface properties of the granules. In the technique is used an emulsifying dispersant comprising as the main component vesicles formed from an amphiphilic substance capable of self-assembly or an emulsifying dispersant comprising single particles of a biopolymer as the main component. The amphiphilic substance capable of self-assembly is selected from among polyoxyethylene hardened castor oil derivatives represented by the general formula (1) wherein the average number of added ethylene oxide molecules is 5 to 15, dialkyldimethylammonium halides wherein the chain length of the alkyl or alkenyl is 8 to 22, and particles made from phospholipids or phospholipid derivatives. According to the invention, a three-phase structure composed of an aqueous phase, an emulsifying dispersant phase and an oil phase is formed on the surface of an emulsion to give an emulsion (such as emulsion fuel) excellent in thermal stability and long-term stability.
