Dissociation Constants of Para Substituted Benzoic Acids in Alcoholic Solutions


Lewis, William Bradley (1933) Dissociation Constants of Para Substituted Benzoic Acids in Alcoholic Solutions. Dissertation (Ph.D.), California Institute of Technology. doi:10.7907/N64X-D109.


The dissociation constants for benzoic and p-chlorobenzoic acids were measured in aqueous solution, and the constants for benzoic, p-chlorobenzoic, p-bromobenzoic, p-iodobenzoic, p-toluic, p-ethyl benzoic, and p-cuminic acids were measured in 80% alcoholic solutions by means of a quinhydrone electrode.

A description of the electrode, and the vacuum tube amplifying circuit used in connection with the potantiometer, is given.

The synthesis of p-toluic, p-ethyl benzoic, and p-cmninic acids is described.
