The present work focused on increasing the yield, energy efficiency, and environmental friendliness of the existing (conventional) method for preparing fire-resistant fluids (FRFs). A series of fire-resistant phosphate esters were synthesized. The reaction occurred vigorously under much milder conditions even without a catalyst if anhydrous alcoholates/phenolates dispersed in an excess of an aromatic hydrocarbon solvent were used. The proposed synthetic method increased the yield of target product by —10% as compared with the conventional one. In addition, the phosphate esters obtained by this method were practically free of tars even before vacuum distillation and had acceptable color and optical density. The proposed technology for synthesizing phosphate esters could produce FRFs with the physicochemical and operating properties required to operate over broad ranges depending on the product application by varying the quantitative and qualitative compositions of the alcohols and/or alkylphenols. In particular, a mixed friary, phosphate with properties meeting basic regulatory requirements for use in power-plant turbine control and lubricating systems was produced.
