Method of producing microcolloidal aqueous emulsions of unsaturated organic compounds

Abstract

Abstract A METHOD OF REDUCING THE MICELLE SIZE OF AN AQUEOUS EMULSION OF AN UNSATURATED ORGANIC COMPOUND UTILIZES AN IONIC PUMPING ACTION TO ACHIEVE MICELLE DIVISION. THE RESIN UTILIZED IS SELECTED ON THE BASIS OF THE PRESENCE IN THE MOLECULAR CHAIN OF A HIGH NUMBER OF SITES WHICH CAN ACCEPT A POSITIVE ION TO CAUSE THE MOLECULE TO ASSUME AN OVERALL CHARGE. A GROSS EMULSION IS FIRST FORMED UTILIZING A SUFFICIENT QUANTITY OF SURFACTANT SO THAT AN EXCESS IS PRESENT TO ASSURE SURFACING OF THE NEWLY FORMED MICELLES UPON DIVISION OF THE MICELLES OF THE INITIAL EMULSION. THE RESIN IS EQUILIBRATED UTILIZING A COMPOUND CAPABLE OF DONATING POSITIVE IONS TO THE RESIN MOLECULE TO CAUSE THE MOLECULE TO ASSUME A CHARGE OF THE SAME SIGN AS THE SIGN OF THE CHARGE ON THE EMULSION MICELLES. THE RESULTING IN CREASED CHARGE IN THE EMULSION RESULTS IN DIVISION OF THE MICELLES INTO MICELLES OF A SMALLER SIZE. THE RESIN PUMPING ACTION CAN BE CONTINUED UNTIL THE MICELLES OF THE EMULSION ARE CHARACTERIZED BY AN INABILITY TO REFLECT LIGHT OF A VISIBLE WAVELENGTH. THE INVENTION ALSO PROVIDES FOR A METHOD OF KILLING INSECTS WHEREIN A MICROEMULSION OF AN UNSATURATED ORGANIC COMPOUND HAVING INSECTICIDAL PROPERTIES IS PREPARED IN THE MANNER SET FORTH ABOVE. AN ADDITIONAL STEP IS THE INCLUSION OF A CHELATING AGENT FOR THE CALCIUM IONS WHICH ARE PRESENT IN THE BASIL MEMBRANE OF AN INSECT. THIS ALLOWS THE EMULSION MICELLES OF THE INSECTICIDE TO PENETRATE THROUGH THE INSECT.
