The titration methods used for the determination of the Neutralization Number for biodiesel fuel production are discussed.
Methyl esters is the chemical name for biodiesel and glycerin is used in a variety of products, including soap. endobj 3080: Open access peer-reviewed.

The darker-colored crude glycerin has settled to the bottom.It is important to realize that unmodified vegetable oil, sometimes called straight vegetable oil (SVO) or waste vegetable oil (WVO), is not biodiesel.

When they react with methanol or ethanol, they make methyl or ethyl esters and a new alcohol called glycerol or, more commonly, glycerin.The chemical reaction used to make biodiesel requires a catalyst.

Biodiesel Production Methods Biodiesel production methods have evolved over the past 30 years from batch types to semi-continuous flow arrangements to true continuous flow schemes. %PDF-1.5 4 0 obj More discussion of SVO and WVO can be found.Biodiesel is usually preferred over SVO and WVO because the chemical reaction converts the oil or fat into compounds that are closer to the hydrocarbons found in regular diesel fuel.The chemical reaction that converts a vegetable oil or animal fat to biodiesel is called “transesterification.” This is a long name for a simple process of combining a chemical compound called an “ester” and an alcohol to make another ester and another alcohol. The primary problem is the high viscosity and low volatility of the unmodified vegetable oils.

In this work it is made a review of the alternative technological methods that could be used to produce this fuel.
