Paper Abstract

Results of preliminary studies of thermo- and photostability of 6CHBT and Demus' esters, based on the measurement of the current passing through the sample, are presented. Different purification techniques for 6CHBT are compared. It was found that the best technique of additional purification is adsorption on neutral silica gel. Good results were also obtained when a combined method was used (zinc dust + carbon + silica gel). 6CHBT is resistant to high temperature only when placed in a vacuum but is rather photostable in vacuum and in air. Demus' esters are thermally stable both in the air and in vacuum but they are not resistant to UV-radiation.
