2. Study of antioxidant property of a thiosphorated compound derived from cashew nut shell liquid in hydrogenated naphthenics oils
The present work shows the aspects related to the synthesis and thermogravimetric analysis of thiophosphorated and phosphorated compounds from hydrogenated cardanol. Studies on thermal-oxidative stability were investigated, using a classical thermoanalytical-thermogravimetric method (TG/DTG) in an air atmosphere. Its use as an antioxidant additive in hydroge

3. Determination of moisture content and water activity in algae and fish by thermoanalytical techniques
The water content in seafoods is very important since it affects their sensorial quality, microbiological stability, physical characteristics and shelf life. In this study, thermoanalytical techniques were employed to develop a simple and accurate method to determine water content (moisture) by thermogravimetry (TG) and water activity from moisture content v

4. Estudo da decomposição térmica de propelente sólido compósito de baixa emissão de fumaça
The thermal decomposition of hydroxyl-terminated polybutadiene (HTPB)/ammonium nitrate (AN) based propellants, so called smokeless formulations, and raw materials were investigated by differential scanning calorimetry (DSC) and thermogravimetry (TG). The thermoanalytical profile of different components and of propellant were evaluated and the Arrhenius param

5. Thermoanalytical studies of the sweeteners acesulfame-K, aspartame, ciclamate, stevioside and sacharine / Estudos termoanalíticos dos edulcorantes acessulfame-K, aspartame, ciclamato, esteviosídeo e sacarina
In this work the thermal decomposition of the non-caloric sweeteners acesulfame-K, aspartame, sodium ciclamate, stevioside, saccharine and sodium saccharine was performed. Initially, the compounds were characterized usually elemental analysis and IR spectroscopy some were recrystallised from commercial samples, resulting in purified compounds. After characte

6. CaracterizaÃÃo e desenvolvimento de mÃtodos analÃticos do ornidazol
The nitroimidazoles drugs acts to inhibit the synthesis of microbial DNA, this class presents the metronidzole as drug of choice. The ornidazol, derivative of the 5-nitroimidazoles, presents therapeutic advantages in relation to metronidazole, by presenting a bigger half-life, causing the reduction in the dosage frequency and the duration of the treatment in
