What is a transesterification reaction?

In organic chemistry, transesterification is defined as the reaction that occurs between an ester and an alcohol in which the alkoxy group of the ester is replaced by alcohol and vice versa. These reactions are often catalyzed by acids or bases.

What is transesterification process for biodiesel production?

The transesterification of vegetable oils, animal fats or waste cooking oils is the process behind conventional biodiesel. In the transesterification process a glyceride reacts with an alcohol (typically methanol or ethanol) in the presence of a catalyst forming fatty acid alkyl esters and an alcohol.

What is the chemistry of biodiesel?

Biodiesel is made through a chemical process called transesterification whereby the glycerin is separated from the fat or vegetable oil. The process leaves behind two products – methyl esters and glycerin. Methyl esters is the chemical name for biodiesel and glycerin is used in a variety of products, including soap.

How are reaction kinetics used in biodiesel production?

TURNER, TIMOTHY LAWRENCE. Modeling and Simulation of Reaction Kinetics for Biodiesel Production. (Under the direction of Richard R. Johnson and William L. Roberts) Biodiesel has emerged as a viable substitute for petroleum diesel. The fuel can be made easily from either virgin or waste vegetable oil. A common means of production

Is the kinetics of transesterification for biodiesel controversial?

of the kinetics of transesterification for biodiesel remains controversial. There are conflicting findings as to the order of reaction, and estimates of reaction rate constants vary widely. After analyzing the prior work on kinetics, this thesis gives support to a kinetic model

How is the glycerolysis reaction of biodiesel determined?

The rate of the glycerolysis reaction is determined by two variables: the initial concentration of FFA and temperature. Many biodiesel plants run their processes using steam heating systems, and are limited to operating temperatures of 350 degrees Fahrenheit or less.

How is biodiesel made as a substitute for diesel?

Modeling and Simulation of Reaction Kinetics for Biodiesel Production. (Under the direction of Richard R. Johnson and William L. Roberts) Biodiesel has emerged as a viable substitute for petroleum diesel. The fuel can be made easily from either virgin or waste vegetable oil. A common means of production is base-catalyzed transesterification.
