Summary

Nineteen phenothiazines were pyrolyzed and their products analyzed gas chromatographically. The pyrolysis products were compared with those obtained from a similar study of the barbiturates. Tentative identifications have been made of three pyrolysis products. The pyrolyzates of the various phenothiazine derivatives yield gas chromatographie patterns which differentiate among them.

Zusammenfassung

Die Pyrolyseprodukte von 19 Phenothiazinen wurden gaschromato-graphisch analysiert und mit jenen verglichen, die bei einer analogen Untersuchung von Barbituraten erhalten worden waren. Die Identifizierung von drei Pyrolyseprodukten wurde versucht. Die Pyrolysate der verschiedenen Phenothiazinderivate lassen sich gaschromatographisch unterscheiden.

Résumé

On a effectué la pyrolyse de dix-neuf phénothiazines et analysé les produits résultants par chromatographie en phase gazeuse. On a comparé les résultats — ceux obtenus au cours d'une étude semblable sur les barbiturates. On a tenté d'identifier trois produits de pyrolyse. Les produits de pyrolyse de plusieurs dérivé de la phénothiazine donnent en chromatographie en phase gazeuse des enregistrements qui permettent de les différencier.
