摘要：

Recently we reported on tetramethylurea (TMU) as a solvent for potentiometric acid-base titrations (1). It was shown that TMU is indeed a useful solvent and is suitable for differentiating a wide range of acids and bases. Results of the first study indicated that perhaps other methods of detecting the end points also might be investigated. Indicators have proved to be especially helpful in the detection of end points in cases where especially steep potential curves are observed in nonaqueous titrations (2). Because the titration curves obtained in TMU tended to be rather steep, the investigation of suitable indicators seemed an appropriate study. © 1969, American Chemical Society. All rights reserved.
