The invention relates to mixtures of at least one dialkylphosphinic acid of the formula (I) in which R1, R2 are the same or different and are each independently C1-C18-alkyl, C2-C18-alkenyl, C6-C18-aryl, C7-C18-alkylaryl, with at least one alkylphosphonic acid of the formula (II) in which R3 is C1-C18-alkyl, C2-C18-alkenyl, C6-C18-aryl or C7-C18-alkylaryl; to a process for preparation thereof and to the use thereof.

Single ethyl phosphinic acid group containing diethyl phosphinic acid and its salt preparation method

The invention relates to the field of fine organic chemical industry and polymer materials, and particularly relates to a preparation method of diethyl phosphinic acid without monoethyl phosphinic acid group and salt thereof. The preparation method of diethyl phosphinic acid comprises the following steps: uniformly mixing sodium hypophosphite monohydrate, acetic anhydride and organic solvent; adding organic acid and concentrated sulfuric acid or anhydrous sulfuric acid; cooling and standing; filtering and recovering sodium sulfate to obtain an anhydrous phosphinic acid organic acid solution; adding ethylene and dropwise adding a trigger mixture to obtain a first mixture; and distilling and recovering the organic acid and the organic solvent to obtain a product. The preparation method is simple and easy to implement, the monoethyl phosphinic acid is completely converted into diethyl phosphinic acid, and the prepared diethyl phosphinic acid does not contain the monoethyl phosphinic acid group. In the invention, the diethyl phosphinic acid without the monoethyl phosphinic acid group serves as a reactant and reacts with a metal compound, the obtained diethyl phosphinate does not contain impurities such as organic sodium salt, and the generated waste liquid is simple to dispose.
