Abstract
Improvements in the object of the main patent no. 335.945, by "process for obtaining salts of para-dihydroxy-benzenesulfonic acid", characterized by the fact of effecting a double decomposition between the potassium salt of p-dihydroxy acid benzene sulfonic acid and a lithium salt of a mineral or organic acid, in a liquid in which the lithium salt of p-dihydroxybenzenesulfonic acid is soluble and in which the potassium salt formed as a by-product it is little or nothing soluble.
