Acids conjugated to various phenothiazine derivatives are titrated directly with sodium hydroxide, by means of an automatic thermometric titrimeter. The titration curves have sharp breaks, suitable for analytical use, and these are discussed, in the case of promethazine hydrochloride, as functions of various parameters such as pK(a), the solubility of the product and the enthalpy of neutralization (determined in this work).
