Zusammenfassung

Es wurden 15 organische Verbindungen angegeben, bei denen Polymorphie gefunden wurde. 10 davon wurden näher beschrieben, wobei für die Untersuchungen thermomikroskopische, differential- scanning-calorimetrische und IR-spektroskopische Methoden verwendet wurden. Ausführlicher beschrieben wurden 1-Adamantyl-essigsäure, Äthylendiamintetraacetonitril, N-Äthylthioharnstoff, Benzilsäuremethylester, Benzylmalonsäure, Biphenyl-2-carbonsäure, Bis-(cyklohexanon)-oxaldihydrazon, l,4-Bis-[2-(4-methyl-5-phenyl)-oxa-zolyl]benzol, Butyloxycarbonyl-L-alanin-4-nitrophenylester und 3,3-Dimethylglutarsäure.

Summary

Fifteen organic substances in which polymorphism was found are specified. Ten of these were described in detail. Thermomicroscopic, differential scanning calorimetric and IR spectroscopic methods were used for the investigations. 1-Adamantylacetic acid, ethylene diamine tetracetonitrile, N-ethylthiourea, benzyl acid methyl ester, benzyl malonic acid, biphenyl-2-carbonic acid, bis-(cyclohexanone)-oxaldihydrazone, l,4-bis-2-(4-methyl-5-phenyl)-oxazolyl benzene, butyloxycarbonyl-L-alanine-4-nitrophenylester and 3,3-dimethylglutaric acid are described in more detail.
