Abstract

The conditions for the extraction of strychnine with 1,2,2-tetrachloroethane, chloroform, 1,2-dichloroethane and carbon tetrachloride were studied and described. The distribution and extraction constants were calculated for strychnine in selected solvents from the dependence of the extraction yield on the pH at various ionic strengths. In addition, a study was carried out of the extraction properties of the ion associates of strychnine with selected groups of azodyes with identical basic skeleton but different numbers of sulfo groups.
