✦ Synopsis

A method was elaborated to establish the number of sulphonic groups bound to the aromatic ring of aromatic acids by means of a paper electrophoretic separation of the original compound from the derivative. The difference between the mobilities is directly proportional to the number of substituted sulphonic groups.
