=__**Formation of biodiesel.**__=

My reaction is biodiesel. Biodiesel is formed by the combination of soybean oil and sodium methylate. Biodiesel is made from a process called transesterifcation. The two products that are left from this reaction are methyl esters and glycerin. Biodiesel is used take the place of regular diesel and is ussually made from plant oils, such as soybeans or animal fat, instead of petroleum like other diesel. Biodiesel is non-toxic and renewable. Biodiesel is non-toxic and renewable unlike regular diesel because it can be formed through reactions from farming or recycling. It is used to run cars and large trucks with larger engines because they need more power to run. Biodiesel is usually blended with regular diesel so that your engine will not need to go through any changes or modifications.



The origin of biofuels dates back to 1900 when Rudolph Diesel began to experiment with running automobiles on different vegetable oils. Later Henry Ford began to follow in his footsteps using corn oils to run some cars. It wasn't until about the 1970's that pollution became a concern and they need a more healthier fuel to run cars. Biodiesel was what they needed. It is made up of crop oils so it would not pollute the air as much as regular gas or regular diesel. They got into making biodiesel because petroleum began being used to make fuel. This was bad for many reasons. One was that petroleum was very expensive and very hard to come by. Two was because burning petroleum and regular fuel is not good for the environment. They were also forced to find an alternate for fuel because it was limited and the price of that was increasing. Biodiesel is cheap because it is made from many vegetable oils and recyclable goods and form soybean oil. Since biodiesel is used for large truck and bus engines it is sold to gas stations. The gas stations buy it from the biodiesel plants where the fuel is made. Then the gas stations pay for what they bought by charging 18 wheelers and buses for diesel fuel. These companies buy biodiesel because it is much cheaper than regular diesel and gas and also it is a lot better for the environment. Biodiesel is better for the environment because it is made from oils and recyclable items and it prevents against global warming, which is a big problem in the world today. This reaction is still very much alive today and that is a good thing because Biodiesel is a much more environment friendly fuel then regular gas or diesel.

Soybean oil is the main ingredient used in the process of making biodiesel.
