Abstract
A gelling agent for a hydrocarbon fracturing fluid is disclosed, comprising the general formula of: in which X is an OR, NRR, or SRgroup, Ris an organic group having 2-24 carbon atoms, and Ris an organic group or a hydrogen. Y is an NRRor SRgroup, Ris an organic group having 2-24 carbon atoms, and Ris an organic group or a hydrogen. A method of making a gelling agent for a hydrocarbon fracturing fluid is also disclosed. Phosphorus oxyhalide is reacted with a chemical reagent to produce substantially only diester phosphorus 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 phosphorus oxyhalide is then hydrolyzed to produce diester phosphoric acid.
