Abstract

Due to massive production of biodiesel, there is a large exceed of glycerol, beyond the present industrial demand for this substance. The price depreciation of glycerol has made even incineration of this substance for electric energy production a current practice. Several research groups has been working to transform glycerol into more prized products by means of many different approaches, including electrochemical conversion. A critical part of these studies is the identification and quantification of the obtained products, which is the very subject of this project. Our proposal is the development of instrumentation and analytical methodology dedicated to the determination of the electrochemically formed derivatives of glycerol. To achieve this goal we will use high efficiency separation techniques, mostly capillary electrophoresis with contactless conductivity detection. We will build equipment capable to allow us to sample and to analyze online, perform sample preparation stages and perform optimized detection of the substances of interest. These implementations will offer valuable resources to the systematic study of the mechanism and electrochemical parameters related to glycerol electro-oxidation, allowing an improvement on the certainty and speed of such research.
