  Phosphate esters useful for gelling hydrocarbons in combination with a metal source are disclosed along with methods of preparation of the phosphate esters. Fouling in oil refinery towers has been attributed due to distillation of impurities present in phosphate esters used to gel hydrocarbons for oil well fracturing. The improved method of preparation of the phosphate ester results in a product that substantially reduces or eliminates volatile phosphorus, which is phosphorus impurities that distill up to 250° C., and increases the high temperature viscosity of the hydrocarbon gels formed using the phosphate esters.

  磷酸酯与金属源结合在一起用于凝胶化烃类物质，并公开了磷酸酯的制备方法。石油精炼塔中的结垢被归因于用于凝胶化油井压裂的磷酸酯中存在的杂质的蒸馏。改进的磷酸酯制备方法导致产品大幅减少或消除挥发性磷，即在250°C以下蒸馏的磷杂质，并增加使用磷酸酯形成的烃类凝胶的高温粘度。
