Abstract
Abstract The viscosity of liquid organic systems is increased by adding thereto an organophilic clay gellant which is the reaction product of a smectite clay having a cation exchange capacity of at least 0.75 milliequivalents per gram and from 1.00 to less than 1.20 milliequivalents per gram of clay of a methyl benzyl dialkyl ammonium salt, wherein the two alkyl groups independently contain from 16 to 18 carbon atoms, and from 0% to 1% water in the absence of a polar organic dispersant for the gellant.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
147 words
A method of increasing the viscosity of a liquid organic system in the absence of a polar organic dispersant comprising mixing with said liquid organic system an amount sufficient to effect said viscosity increase of an organophilic clay comprising the reaction product of a methyl benzyl dialkyl ammonium compound and a smectite clay having a cation exchange capacity of at least 75 milliequivalents per 100 grams of said clay, wherein said alkyl radicals independently contain from 16 to 18 carbon atoms, and wherein the amount of said ammonium compound is sufficient to impart to the organophilic clay the enhanced dispersion characteristics desired, said amount of the ammonium compound being from 100 to less than 120 milliequivalents per 100 grams of said clay, 100% active clay basis, and from 0% to 1.0% water, wherein no polar organic dispersant for said organophilic clay is added to said organic system.
Claim 2
Independent Claim
147 words
A method of increasing the viscosity of a liquid organic system in the absence of a polar organic dispersant comprising mixing with said liquid organic system an amount sufficient to effect said viscosity increase of an organophilic clay comprising the reaction product of a methyl benzyl dialkyl ammonium compound and a smectite clay having a cation exchange capacity of at least 75 milliequivalents per 100 grams of said clay, wherein said alkyl radicals independently contain from 16 to 18 carbon atoms, and wherein the amount of said ammonium compound is sufficient to impart to the organophilic clay the enhanced dispersion characteristics desired, said amount of the ammonium compound being from 100 to less than 120 milliequivalents per 100 grams of said clay, 100% active clay basis, and from 0% to 1.0% water, wherein no polar organic dispersant for said organophilic clay is added to said organic system.
