Process for the production of concentrated aqueous emulsions or insoluble liquid,pasty or solid organic or inorganic substances

Abstract

Abstract CONCENTRATED AQUEOUS EMULSIONS OR DISPERSIONS OD WTER-INSOLUBLE LIQUID, PASTRY OR SOLID ORGANIC OR INORGANIC SUBSTANCES ARE PREPARED WITH EMULSIFIERS WHICH ARE PRODUCED BY THE REACTION OF: (A) ABOUT 1 MOLE OF UREA, GUANIDINE, DERIVATIVES OF GUANIDINE OR THE PRODUCTS OF THE DECOMPOSITION OF GUANIDINE DERIVATIVES, WITH (B) ABOUT 0.25-2.5 MOLES OF AN EPOXY COMPOUND CONTAINING IN THE MOLECULE ON THE AVERAGE MORE THAN ONE EPOXY GROUP, AND (C) ABOUT 0.1-2 MOLES OF AN AMINE OF THE GENERAL FORMULA R1-N(-R2)-R3 WHEREIN R1 REPRESENTS AN ALKYL GROUP HAVING 2-4 CARBON ATOMS OR AN ALKANOL GROUP OF 2-5 CARBON ATOMS, R2 AND R3 REPRESENT HYDROGEN, AN ALKYL GROUP HAVING 1-4 CARBON ATOMS, OR AN ALKANOL GROUP HAVING 2-5 CARBON ATOMS, WHEREIN RR2 AND/OR R3 REPRESENT IDENTICAL OR DIFFERENT GROUPS, AND AT LEAST TWO REACTIVE HYDROGEN ATOMS ARE PRESENT IN THE MOLECULE OF THE GENERAL FORMULA, UNDER HEATING, PREFERABLY IN THE PRESENCE OF WATER-MISCIBLE SOLVENTS BOILING AT MORE THAN ABOUT 50*C.
