Method of preparing quaternary ammonium naphthenates

Claim 1

THE METHOD OF PREPARING AN OIL SOLUBLE, WATER DISPERSIBLE QUATERNARY AMMONIUM NAPHTHENATE HAVING ANTIMICROBIAL PROPERTIES WHICH COMPRISES MIXING IN AQUEOUS SOLUTION A QUANTERNARY AMMONIUM HALIDE REACTANT SELECTED FROM THE GROUP CONSISTING OF QUANTERNARY AMMONIUM CHLORIDES, BROMIDES AND IODIDES HAVING ATTACHED THERETO A LONG CHAIN ALKYL GROUP CONTAINING BETWEEN EIGHT AND EIGHTEEN CARBON ATOMS, AND A WATER-SOLUBLE SALT OF NAPHTHENIC ACID REACTANT, SAID QUANTERNARY AMMONIUM HALIDE REACTANT AND THE NAPHTHENATE SALT REACTANT BEING REACTED IN SUBSTANTIALLY EQUIMOLAR AMOUNTS AND THE COMBINED WEIGHT OF SAID REACTANTS BEING AT LEAST ABOUT FIVE PERCENT BY WEIGHT OF THE TOTAL WEIGHT OF THE REACTANTS AND THE WATER WHICH TOGETHER MAKE UP THE REACTION MIXTURE, AGITATING SAID REACTANTS UNTIL THEY REACT TO FORM (1) AN UPPER OILY LAYER CONTAINING SUBSTANTIALLY ALL OF THE QUANTERNARY AMMONIUM NAPHTHENATE REACTION PRODUCT, ANY WATER CONTAINED IN SAID LAYER BEING DISSOLVED IN SAID REACTION PRODUCT, AND (2) A LOWER AQUEOUS LAYER CONSISTING ESSENTAILLY OF A SOLUTION OF THE SALT OF THE HALOGEN AND THE CATION FROM THE SALT OF NAPHTHENIC ACID REACTANT, SAID AQUEOUS LAYER BEING SUBSTANTIALLY FREE OF QUATERNARY AMMONIUM NAPHTHENATE REACTION PRODUCT, AND EFFECTING PHYSICAL SEPARATION OF SAID OILY LAYER OF QUATERNARY AMMONIUM NAPHTHENATE FROM SAID AQUEOUS LAYER BY WITHDRAWING ONE OF SAID LAYERS FROM THE OTHER LAYER.

Claim 2

THE METHOD OF PREPARING AN OIL SOLUBLE, WATER DISPERSIBLE QUATERNARY AMMONIUM NAPHTHENATE HAVING ANTIMICROBIAL PROPERTIES WHICH COMPRISES MIXING IN AQUEOUS SOLUTION A QUANTERNARY AMMONIUM HALIDE REACTANT SELECTED FROM THE GROUP CONSISTING OF QUANTERNARY AMMONIUM CHLORIDES, BROMIDES AND IODIDES HAVING ATTACHED THERETO A LONG CHAIN ALKYL GROUP CONTAINING BETWEEN EIGHT AND EIGHTEEN CARBON ATOMS, AND A WATER-SOLUBLE SALT OF NAPHTHENIC ACID REACTANT, SAID QUANTERNARY AMMONIUM HALIDE REACTANT AND THE NAPHTHENATE SALT REACTANT BEING REACTED IN SUBSTANTIALLY EQUIMOLAR AMOUNTS AND THE COMBINED WEIGHT OF SAID REACTANTS BEING AT LEAST ABOUT FIVE PERCENT BY WEIGHT OF THE TOTAL WEIGHT OF THE REACTANTS AND THE WATER WHICH TOGETHER MAKE UP THE REACTION MIXTURE, AGITATING SAID REACTANTS UNTIL THEY REACT TO FORM (1) AN UPPER OILY LAYER CONTAINING SUBSTANTIALLY ALL OF THE QUANTERNARY AMMONIUM NAPHTHENATE REACTION PRODUCT, ANY WATER CONTAINED IN SAID LAYER BEING DISSOLVED IN SAID REACTION PRODUCT, AND (2) A LOWER AQUEOUS LAYER CONSISTING ESSENTAILLY OF A SOLUTION OF THE SALT OF THE HALOGEN AND THE CATION FROM THE SALT OF NAPHTHENIC ACID REACTANT, SAID AQUEOUS LAYER BEING SUBSTANTIALLY FREE OF QUATERNARY AMMONIUM NAPHTHENATE REACTION PRODUCT, AND EFFECTING PHYSICAL SEPARATION OF SAID OILY LAYER OF QUATERNARY AMMONIUM NAPHTHENATE FROM SAID AQUEOUS LAYER BY WITHDRAWING ONE OF SAID LAYERS FROM THE OTHER LAYER.
