Some new indicators derived from vanillin: 4-hydroxy-3-methoxy-[beta]-nitrostyrene and homologues. Stewart, Ross

Abstract

Vanillin has been condensed with certain nitroparaffins to produce four compounds with indicator properties. The benzoyl derivatives of two of these were also synthesized. The colour change, pH range, and indicator constant were measured for each of the four indicators.
