J. Nurit et al., POLYMORPHISM AND ANALYSIS OF THE THERMAL- BEHAVIOR OF A SERIES OF 3-(ALPHA-HYDROXYIMINOARYL)-1,2,2-TRIMETHYL CYCLOPENTANE CARBOXYLATE, Journal of thermal analysis, 45(3), 1995, pp. 535-558
The infrared, H-1 NMR and X-ray diffraction characteristics of a serie
s of 3-(alpha-hydroxy-imino-aryl)-1,2,2-trimethyl cyclopentane carboxy
late are reported. The thermal analysis of this series has been studie
d by differential scanning calorimetry. The results show a large varie
ty of thermal behaviours with some of the compounds exhibiting polymor
phism and the two types of isomers were detected.
