COMPARATIVE-ANALYSIS OF SOME MEDITERRANEA N PLANTS BY THERMAL AND CHEMICAL-ANALYSIS

Thermal analysis can be used for the behaviour of plants during heatin g and most particularly in the risk prevention of forest fire. Cellulo se, holocellulose and lignin are the most important compounds determin ated by analytical procedures in six mediterranean vegetals: Acacia de albata, Pinus halepinsis, Quercus coccifera, Rosmarinus officinalis, T hymus vulgaris, Ulex parviflorus. TG-DTA is applied to the powders obt ained after drying (110 degrees C), pounding and sifting. The rate of pyrolysis about 300 degrees C allows a semi-quantitative estimate of t he cellulose present in the vegetal and its flammability.
