    Description / Table of Contents:
    Résumé On a suivi par ATD et à l'aide d'un derivatograph le comportement thermique des polyalcools suivants: D-mannitol, dulcitol, D-sorbitol, D-sorbitol hémihydraté, L-arabitol, xylitol et adonitol. Tous sont stables jusqu'à 200–250°C. Le pic endothermique qui apparaît sur la courbe d'ATD à plus basse température est dû à la fusion. Celle-ci ne s'accompagne pas d'un accroissement de la conductivité électrique. Les hexitols se décomposent endothermiquement avec ébullition simultanée au-dessus de 200–250° et élimination de la majeure partie des produits de décomposition; le résidu est oxydé. La décomposition des pentitols s'accompagne au début d'un effet exothermique.
    Abstract:
    Zusammenfassung Das thermische Verhalten von D-Mannitol, Dulcitol, D-Sorbitol, vom Semihydrat des D-Sorbitol, von L-Arabitol, Xylitol und Ribitol wurde differentialthermoanalytisch und derivatographisch untersucht. Diese Polyole waren bis 200–250° stabil. Die endothermische Spitze der DTA-Kurve bei niedrigerer Temperatur ist dem Schmelzen zuzuschreiben, welches durch kein Erhöhen der elektrischen Leitfähigkeit begleitet ist. Hexitole zersetzen sich endotherm in ähnlicher Weise beim Sieden über 200–250°, der größte Teil der Zersetzungsprodukte entfernt sich und der Rückstand wird oxydiert. Der Zersetzungsbeginn der Pentitole ist von einem exothermen Effekt begleitet.
    Notes:
    Abstract The thermal behaviour of D-mannitol, dulcitol, D-sorbitol, the semihydrate of D-sorbitol, L-arabitol, xylitol and ribitol was investigated by means of differential thermal analysis and a derivatograph. All these polyols are stable up to 200–250°. The endothermic peaks on the DTA curves at lower temperatures are due to melting. These effects are not accompanied by an increase in the electric conductivity. The hexitols decompose endothermally at boiling above 200–250°, the majority of the decomposition products boil out, and the residue is oxidized. The beginning of the decomposition of the pentitols is accompanied by an exothermic peak.

    Notes:
    Abstract The DTA, TG, DTG and electric conductivity curves of pentaerythritol (I), 1,3-dihydroxy-2-methylol-2-ethylpropane(II) and 1,3-dihydroxy-2-methylol-2-methylpro-pane(III) have been taken for the first time. Pentaerythritol undergoes a polymorphous change on heating, 1,3-dihydroxy-2-methylol-2-methylpropane forms a syrup in a narrow temperature interval before melting and 1,3-dihydroxy-2-methylol-2-ethylpropane melts with formation of a glass on cooling. The sublimation of substances was also observed.
