Thermophysical Properties in Medium Temperature Range of Several Thio and Dithiocarbamates

The present study reports a DSC study of the thio-and dithiocarbamates: 3 H -benzoxazole-2-thione (2-mercaptobenzoxazole), 3 H -benzothiazole-2-thione (2-mercaptobenzothiazole), thiazolidine-2-thione (2-mercapto-2-thiazoline), oxazolidine-2-thione (2-mercapto-2-oxazoline) and tetrahydro-1,3-oxazine-2-thione (5,6-dihydro-4 H -1,3-oxazine-2-thiol) in the temperature interval  T =268 K and the melting temperatures. Temperatures, enthalpies and entropies of fusion are reported. No solid-solid phase transitions were observed for the compounds in the temperature interval studied. The heat capacity of the compounds as a function of temperature was measured.
