Griffin, Jr, T J

The ester-type product is formed by reacting an essentially anhydrous hydroxy ether with a pentavalent phosphorus compound which is substantially free from acid groups such as Cl, F, and the like. When the total carbon atoms in the hydroxy ether is 3 or 4, there also is reacted with the hydroxy ether and phosphorous compounds a long chain aliphatic monohydric alcohol containing at least 5 carbon atoms. To gel an organic liquid the reaction product is dispersed into an organic liquid along with an aluminum activator such as an alkali metal aluminate, aluminum isoproproxide, hydrated alumina or the like, the reaction product and the activator being employed in amounts and a specific ratio to each other to impart to the organic liquid a desired viscosity. The gelled organic liquid can be employed as a fracturing fluid, as a carrying liquid for solids, and other utilities where organic liquids having a viscosity which is greater than the normal viscosity of the organic liquid is useful. 37 claims.
