Resumo: Polarised light microscopy and DTA have been used to study the phase transitions observed in cis and trans-1,2-cyclohexanediol during heating/cooling cycles performed between ambient and melting temperatures to prove that the presence of impurities even in trace amounts can affect the thermal properties of the substances. Good quality commercial material before and after further purification were used in this study.
