Organophilic bentonite and greases produced therefrom

Claim 1

A BENTONITE COMPLEX CONSISTING ESSENTIALLY OF THE REACTION PRODUCT OF BENTONITE AND (A) A POLYQUARTERNARY AMMONIUM COMPOUND HAVING FROM 2-5 QUATERNARY AMMONIUM GROUPS, SAID POLYQUARTERNARY AMMONIUM COMPOUND BEING THE REACTION PRODUCT OF (1) AN AMINE SELECTED FROM THE GROUPS CONSISTING OF TERTIARY MONOAMINES AND TERTIARY DIAMINES, THE NITROGEN ATOMS OF SAID AMINES BEING SELECTED FROM THE GROUP CONSISTING OF NITROGEN ATOMS IN A HETEROCYCLIC RING AND ALKYL SUBSTITUTED NITROGEN ATOMS IN WHICH THE ALKYL SUBSTITUENTS CONTAIN FROM 1-22 CARBON ATOMS AND (2) A DIHALIDE SELECTED FROM THE GROUP CONSISTING OF DIHALIDES IN WHICH THE HALOGEN ATOMS ARE SEPARATED BY AN ALKYLENE GROUP CONTAINING FROM 2-6 CARBON ATOMS AND DIHALIDES IN WHICH THE HALOGEN ATOMS ARE SEPARATED BY A POLYOXYALKYLENE GROUP CONTAINING FROM 2-6 RECURRING UNITS, EACH ALKYLENE GROUP CONTAINING FROM 2-6 CARBON ATOMS, AND (B) A MONOQUATERNARY AMMONIUM COMPOUND HAVING TWO LONG CHAIN ALKYL GROUPS ATTACHED TO THE NITROGEN ATOM, EACH OF SAID LONG CHAIN ALKYL GROUPS CONTAINING FROM 8-22 CARBON ATOMS, SAID NITROGEN ATOMS BEING SELECTED FROM THE GROUP CONSISTING OF NITROGEN ATOMS SUBSTITUTED WITH TWO SHORT CHAIN ALKYL GROUPS CONTAINING FROM 1-4 CARBON ATOMS AND NITROGEN ATOMS FORMING PART OF A HETEROCYCLIC RING, THE QUANTITY OF (A) BEING LESS THAN ONE EQUIVALENT PER TEN EQUIVALENTS OF (B) BUT SUFFICIENT TO MATERIALLY STIFFEN A GREASE MADE FROM SAID COMPLEX, THE TOTAL QUANTITY OF (A) AND (B) BEING SUCH THAT SUBSTANTIALLY ALL OF THE EXCHANGEABLE METAL CATION IN THE BENTONITE IS REPLACED BY THE CATIONS OF (A) AND (B).
