摘要 |
<p>A process for the preparation of mono, di or trisulfonated aryl phosphines whereby triaryl phosphine is sulfonated with oleum at 0 DEG to 40 DEG C. After dilution of the reaction product with water, the sulfonated triaryl phosphine is extracted with an amine dissolved in an organic solvent; both the amine and organic solvent being insoluble in water.
