摘要: The sulfonation of arylphosphines, i.e. mono-, di-, oligo- and polyphosphines, which contain at least one aromatic radical capable of being sulfonated, is carried out in the presence of a Lewis acid at 0.degree. to 80.degree. C. The process avoids side-reactions, in particular the formation of phosphine oxides. In treating the sulfonation mixture, the Lewis acid can be removed together with the sulfuric acid.

摘要: The invention relates to a method for producing sulfonated aryl phosphines by reacting aryl phosphines with oleum. After reacting the aryl phosphines with oleum, the sulfonation mixture is firstly diluted with water and an inert gas stream is then fed through the diluted sulfonation mixture until SO2 is no longer released from the diluted sulfonation mixture. Afterwards, the sulfonation mixture is subsequently processed in a usual manner. The invention also relates to a method for producing solutions of sulfonated aryl phosphines by reacting the aryl phosphines with oleum, diluting the sulfonation mixture with water, extracting the aqueous solution using an organic solution consisting of an amine, and subsequently carrying out a reextraction using an aqueous solution having an inorganic base. According to the invention, the solution containing aqueous sulfonated aryl phosphines is adjusted to a pH value of up to 3 by adding acid, and an inert gas stream is then fed through the aqueous solution until sulfur dioxide is no longer released. The invention additionally relates to an aqueous catalyst solution containing rhodium and an aqueous solution of sulfonated aryl phosphines, treated as defined by the invention, for carrying out the hydroformylation of olefinically unsaturated compounds, and relates to the use thereof for carrying out the same.
