Abstract

DTA/SDTG and DSC techniques were used to study the thermal behaviors of citronellol- -D-glucopyranoside (CGLY) . The heating rate was 5, 7.5, 10, and 12.5 K min-1, the samples were heated from 30oC to 500oC. Methods of Friedman and Flynn-Wall-Ozawa were applied to calculate the parameters of thermal degradation, the parameters were substituted to the methods of Coats-Redfern and Phadnis-Deshpande to estimated degradation mechanism. The TG-DTG curves showed that with the increased heating rate, the mass of starting loss T0, the biggest rate of mass loss Tp and final mass loss Tf met the functions respectively: T0=3.8825B+194.97, Tp=2.2825B+281.47, Tf=5.5825B+305.72. The DSC curve showed that melting and decomposition proceeded at sametime. By Friedman and Flynn-Wall-Ozawa, thermal degradation of the apparent activation energy Ea are obtained, which are 133.15 KJ/mol, 126.62KJ/mol respectively, and the correlation was related.
