The reaction of phosphorus trichloride with a number of monobasic carboxylic acids has been studied and the optimum ratio of reactants for the yield of acid chlorides has been established.Based on analysis and the data from 31P NMR spectroscopy of the phosphorus-containing products from this reaction it is shown that at 40-50 deg C a mixture of P-H acids having a predominant content of pyrophosphorous acid is formed.
