Michel-Levy Birefringence Chart
The birefringence of a anisotropic material can be estimated when observed and/or
photographed in a polarized light microscope. A relationship between interference color and
retardation can be graphically illustrated in the
Reaction Mechanism for Transesterification
Transesterification is the conversion of a carboxylic acid ester into a different carboxylic acid ester.
When an ester is placed in a large excess of an alcohol along with presence of either an acid

What Is Biodiesel?
Biodiesel is an alternative fuel similar to conventional or fossil diesel. Biodiesel can be
produced from straight vegetable oil, animal oil/fats, tallow and waste cooking oil. The process
