Two major categories of methods besides other miscellaneous ones have been reported in the literature for assessing biodiesel fuel quality and/or monitoring the transesterification reaction by which biodiesel is produced. The two major categories comprise chromatographic and spectroscopic methods. This article considers the various methods in each category, including advantages and drawbacks, and offers suggestions on selection of appropriate methods.

It is obtained by reacting the parent vegetable oil or fat with an alcohol (transesterification) in the presence of a catalyst to give the corresponding monoalkyl esters, which are defined as biodiesel. Because of the nature of the starting material, the production process, and subsequent handling, various factors can influence biodiesel fuel quality. Fuel quality issues are commonly reflected in the contaminants or other minor components of biodiesel. This work categorizes both the restricted species in biodiesel and the physical properties prescribed by the standards, and details the standard reference methods to determine them as well as other procedures. Other aspects of biodiesel analysis, including production monitoring and assessing biodiesel/petrodiesel blends, are also addressed. The types of analyses include chromatographic, spectroscopic, physical properties-based, and wet chemical methods. The justifications for specifications in standards are also addressed.

In the second part, analytical aspects for the determination of free and bonded glycerol, as well as mono-, di-and triglycerides are described. Well tested methods for the analysis of glycerol and glycerides are presented, including the desctiption of the advantages and disadvantages of each method. 0 1996 Elsevier Science Ltd.
