What is the molecular weight of biodiesel?
The molar mass of biodiesel has been determined as 294.86 kg kmol−1.
What is the formula for biodiesel?
Although a mixture, the basic biodiesel chemical formula is C17H34O2, with the ester group –CO2CH3 at the end of the long carbon chain.
How do you find the molecular weight of biodiesel?
The molecular weight of obtained biodiesel in the three samples is very similar and its value is about 293 g/mol (Table 5). According to Van Gerpen [38], the approximate biodiesel molecular weight is calculated as a third of the molecular weight corresponding to the triglyceride from which it proceeds.
What is the purpose of NaOH in the production of biodiesel?
The NaOH catalyst first reacts with the methanol, reducing it to a methoxide which then attacks the triglycerides in the oil breaking it into fatty acid methyl esters (FAME) and glycerol. Fig. 1. Graph of biodiesel yield against amount of NaOH used (“the line is a guide to the eye”).
What is the molar mass of Naoh?
39.997 g/mol
Sodium hydroxide/Molar mass
What is the density of biodiesel in g mL?
Theory: What is biodiesel? Why can biodiesel be used as a fuel?
| Substance | Density (25°C, 101.3 kPa) g mL-1 | Relative Density |
|---|---|---|
| glycerol | 1.26 | more dense |
| biodiesel | ≈ 0.88 | less dense |
What is B20 biodiesel?
B20 fuel is a blend of 20-percent biodiesel and 80-percent conventional diesel, which helps lower carbon dioxide emissions and lessens dependence on petroleum. The announcement was made at the National Biodiesel Conference.
What is B100 biodiesel?
B100 biodiesel (100% biodiesel) is an EPA -registered fuel and fuel additive designed as a blendstock for use in blending with petroleum diesel. Biodiesel has been shown to reduce the emissions of hydrocarbons, carbon monoxide and particulate when used alone or as a blend (B5, B20).

How is biodiesel made transesterification?
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.
