Biodiesel is a clean burning substitute for petroleum based diesel

fuel. Biodiesel is made of vegetable oil

    = Paragraph 1 is General Statement

To make or manufacture Biodiesel, you must first start with raw

materials. The raw materials needed in the production of

Biodiesel are a small amount of methanol and a ready supply of

vegetable product. One of the most common vegetables used in

the production of Biodiesel is corn, although depending on the

geographic location of the manufacturing facility many other

plants are used as well (rapeseed, soybeans, flaxseed, etc.). The

first step is to use the raw vegetable product to make vegetable

oil. Vegetable oil by itself will not be what you need to power a

car, from here it has to be processed into Biodiesel.

    = Paragraph 2 is Sequenced Explanation

The process for converting vegetable oil into Biodiesel is

sometimes called ester interchange. To complete this process the

vegetable oil has to be combined with a smaller amount of

methanol and then put in the presence of a small quantity of an

alkaline catalyst (for example, 5% to 1% sodium hydroxide).

Vegetable oil is made up of so-called triglycerides, which is a

compound of the trivalent alcohol glycerin with three fatty acids.

The goal of ester interchange is to separate the glycerin

molecule from the three fatty acids and replace it with three

methanol molecules

   = Paragraph 3 is Sequenced Explanation

This process then yields roughly 90% Biodiesel and 10% of a

glycerin byproduct. The glycerin byproduct can be used in a

number of other chemical processes for different industries.
