<p>A gelling agent for a hydrocarbon fracturing fluid is disclosed, comprising the general formula of: in which X is an OR1, NR1R2, or SR1 group, R1 is an organic group having 2-24 carbon atoms, and R2 is an organic group or a hydrogen. Y is an NR3R4 or SR3 group, R3 is an organic group having 2-24 carbon atoms, and R4 is an organic group or a hydrogen. A method of making a gelling agent for a hydrocarbon fracturing fluid is also disclosed. Phosphoais oxyhalide is reacted with a chemical reagent to produce substantially only diester phosphoais oxyhalide, the chemical reagent comprising at least one of an organic alcohol having 2-24 carbon atoms, an organic amine with an organic group having 2-24 carbon atoms, and an organic sulfide having 2- 24 carbon atoms. The diester phosphoais oxyhalide is then hydrolyzed to produce diester phosphoric acid.</p> |
