Biodiesel (methyl esters) is a clean alternative fuel which can be produced from many renewable resources. Palm oil like other vegetable oils can be used as feedstock for biodiesel production. It is processed through transesterification to produce palm oil methyl ester.Palm oil contains a high concentration of palmitic acid (about 45-48%), and oleic acid (37-38%) ( Figure 4(a)). In addition, the fatty acid content can be classified as saturated acid (50%), monosaturated fatty acids (40%), and polyunsaturated fatty acids (10%) [94] .

What are the properties of palm oil?
Some important physical properties of palm oil include solid fat content, viscosity, density, specific gravity, and refractive index. Research on phase transitions and polymorphism in palm oil has been also widely reported.
What chemicals are in palm oil?
Chemical composition
The oil palm gives its name to the 16 carbon saturated fatty acid palmitic acid found in palm oil; monounsaturated oleic acid is also a constituent of palm oil while palm kernel oil contains mainly lauric acid. Palm oil is the largest natural source of tocotrienol, part of the vitamin E family.
What is the chemical formula of palm oil?
Glycerides, palm-oil mono-and di-, hydrogenated, 3-oxododecanoates | C15H29O5- – PubChem.
Is palm oil a compound or element?
Triacylglycerol is a chemical compound consisting of three elements; carbon, hydrogen and oxygen. These elements make up molecules of fatty acids and glycerol, which combine to form fat molecules known as triacylglycerols.

What is palm oil ester?
Palm oil like other vegetable oils can be used as feedstock for biodiesel production. It is processed through transesterification to produce palm oil methyl ester. Enzymatic reactions catalyzed by lipases are potentially excellent processes to produce biodiesel through the transesterification reaction.
What is methyl ester used for?
Methyl ester is intended to be used as a replacement for petroleum diesel or it can be blended with petroleum diesel fuel in any proportion, so called, “Biodiesel” and is generally regarded as being more environmentally friendly.
Does palm oil contain ester?
Palm oil, like all fats, is composed of fatty acids, esterified with glycerol. Palm oil has an especially high concentration of saturated fat, specifically the 16-carbon saturated fatty acid, palmitic acid, to which it gives its name. Monounsaturated oleic acid is also a major constituent of palm oil.
Is methyl ester The same as biodiesel?
Biodiesel (methyl-ester) is an option proposed to substitute fuel-based fuel because it is vegetable oil-based fuel which is renewable and environmentally friendly [7]. Compared to other fuel, biodiesel is biodegradable and non-toxic; it also has low CO2 emission and sulfuric gas content [8].

What does palm oil contain?
Palm oil contains saturated and unsaturated fats. Some types of palm oil contain vitamin E and beta-carotene. These types of palm oil might have antioxidant effects. Refined palm oil is made by bleaching, deodorizing, and neutralizing crude palm oil.
Is coconut oil a ester?
Regiospecific analysis has shown that in coconut oil, lauric and linoleic acids are esterified mainly in the sn-2 position and oleic acid and saturated acids in the sn-1(3) positions (Table 2).
What are esters in vegetable oil?
The esters of vegetable oils or animal fats appear to be the most promising alternative. Today, methyl or ethyl esters of fatty acids are used as substitute to petroleum-based diesel fuels under the name of “biodiesel” [3].

Is methyl ester hazardous?
Harmful if swallowed. Material may be irritating to the mucous membranes and upper respiratory tract. May be harmful by inhalation, ingestion, or skin absorption. May cause damage to {organs} through prolonged or repeated exposure.
What are fatty acid methyl esters used for?
Fatty acid methyl esters (FAME) are a type of fatty acid ester that are derived by transesterification of fats with methanol. The molecules in biodiesel are primarily FAME, usually obtained from vegetable oils by transesterification. They are used to produce detergents and biodiesel.
Is methyl ester an alcohol?
The most commonly used alcohol is methanol, producing fatty acid methyl esters (FAME). When ethanol is used fatty acid ethyl esters (FAEE) are created. Other alcohols used for the production of biodiesel include butanol and isopropanol.
