In the chlorination of dimethyl hydrogen phosphite the purity of the dimethyl phosphorochloridate obtained is influenced by the presence of hydrogen chloride in the reaction mixture and the ingress of water into the reaction sphere. With the aid of /sup 31/P NMR spectroscopy it was shown that, when moisture finds its way into the sphere of reaction, in the further distillation of the crude reaction mixture, apart from the latter, trimethyl phosphate formed as a result of the breakdown of tetramethyl pyrophosphate also distills off.
