POCl3 reacts with water to give hydrogen chloride and phosphoric acid: O=PCl3 + 3 H2O → O=P(OH)3 + 3 HCl Intermediates in the conversion have been isolated, including pyrophosphoryl chloride, O(POCl2)2. Upon treatment with excess alcohols and phenols, POCl3 gives phosphate esters: O=PCl3 + 3 ROH → O=P(OR)3 + 3 HCl
