1. EXPERIMENTO COM ABACATE, BORRA DE CAFÉ, LICURI E LEITE DE COCO PARA EXTRAÇÃO DE ÓLEO, PRODUÇÃO DE BIODIESEL E ANÁLISE ESPECTRAL
An undergraduate organic chemistry experiment for oil extraction and biodiesel production using alternative biomass was developed, whereby oils of avocado, coconut and spent coffee grounds were obtained and submitted to transesterification reaction with CH3OH under NaOH catalysis. Avocado and coffee oils were obtained by typical extraction and coconut oil wa

2. PRODUÇÃO DE BIODIESEL A PARTIR DE ÁCIDOS GRAXOS PROVENIENTES DO REFINO DE ÓLEOS VEGETAIS VIA CATÁLISE ÁCIDA HETEROGENEA E MICRO-ONDAS
This work presents the biofuel production results of the esterification of fatty acids (C12-C18) and high-acid-content waste vegetable oils from different soap stocks (soybean, palm, and coconut) with methanol, ethanol, and butanol by acid catalysis. We used Amberlyst-35 (A35) sulfonic resin as a heterogeneous acid catalyst and p-toluenesulfonic acid as a ho

3. Obtention and characterization of coconut babassu derivatives
Babassu (Orbignya sp.) is a palm with extraordinary socioeconomic and ecologic importance found in humid tropical areas in Brazil, especially in frequently burned and degraded landscapes. There are several uses for babassu oil; however, its potential for providing other industrial products remains unexploited, due to the lack of scale and production structur

4. Experimental density data and excess molar volumes of coconut biodiesel + n-hexadecane and coconut biodiesel + diesel at different temperatures
The density of the pure component (n-hexadecane), pure pseudo-components (coconut biodiesel and diesel) and pseudo-binary mixtures of coconut biodiesel with n-hexadecane (or + diesel) were measured at temperatures 293.15, 313.15, 333.15, 353.15 and 373.15 K and atmospheric pressure, over the entire composition range (mole fractions from 0.1 to 0.9, with a st

5. Viscosities and viscosity deviations of binary mixtures of biodiesel + petrodiesel (or n-hexadecane) at different temperatures
Viscosities of four binaries mixtures [soybean biodiesel + diesel oil (or n-hexadecane) and coconut biodiesel + diesel oil (or n-hexadecane)] have been determined at T = (293.15, 313.15, 333.15, 353.15, 373.15) K and atmospheric pressure over the entire composition range. Experimental data were fitted to the Andrade equation and the adjustable parameters and

6. Estudo de Propriedades em Excesso de DeterminaÃÃo do EquilÃbrio LÃquido-LÃquido em Sistemas contendo Biodiesel. / Study of Properties in Excess Determination of Liquid-Liquid Equilibrium in Systems containing biodiesel.
Energias renovÃveis ganharam uma atenÃÃo importante nas Ãltimas dÃcadas devido à diminuiÃÃo das reservas de petrÃleo e o crescimento da conscientizaÃÃo ambiental. Elas podem ser produzidas a partir de uma variedade de gorduras e Ãleos vegetais, inclusive oleaginosas como coco e soja. A produÃÃo de biodiesel a partir de Ãleos vegetais à uma da

7. Experimental determination of the data kinetics of transesterification reaction of vegetable oils / Determinação experimental dos dados cineticos da reação de transesterificação de oleos vegetais
The general objective of this study was to contribute with the biodiesel production. More specifically, the purpose is to obtain experimental parameters kinetics of transesterification reaction for alcoholysis reaction of various vegetable oils produced in Brazil, such as palm oil, waste frying, coconut oil, soybean oil and castor oil, being employed various

8. Produção de biodiesel a partir de óleo de coco (Cocos nucifera L
The production of biodiesel has become an important and attractive process for the production of alternative fuels. This work presents a study of the biodiesel production from coconut oil (Cocos nucifera L.), by two routes: direct transesterification using NaOH as catalyst and esterification (with H2SO4) followed by basic transesterification. The reactor was

9. ESTUDO E OTIMIZAÇÃO DO PROCESSO DE PRODUÇÃO DE BIODIESEL METÍLICO DE ÓLEO DE COCO BABAÇU COM AQUECIMENTO POR MICROONDAS USANDO UM DELINEAMENTO COMPOSTO CENTRAL ROTACIONAL (DCCR). / STUDY AND OPTIMIZATION OF PROCESS FOR PRODUCTION METHYL BIODIESEL UNDER MICROWAVE IRRADIATION OF COCO BABASSU USING A CENTRAL ROTATABLE COMPOSITE DESIGN (CRCD)
Generally, the organic reaction heating under microwave irradiation reported reduced reaction time and larger yield. Therefore, way was sought in this work to study and to optimize the transesterification reaction used in biodiesel production with methanol and heating for irradiation microwave using coconut babassu oil. It was used a Central Rotatable Compos
