Why does fractional distillation work? - MyTutor
Why does fractional distillation work? Fractional distillation relies on different fractions in the organic mixture having different boiling points. The difference in these boiling points could be caused by several things but the main determinant is the size of the molecule.
How does fractional distillation work? - MyTutor
Fractional distillation works by using the fact that molecules of different sizes have different boiling points. Generally, the smaller a molecule, the lower its boiling point. When heating up a mixture of molecules, the lowest boiling compound will boil off first.
What is Fractional Distillation and how does it work? - MyTutor
Fractional Distillation is a method used in industry to separate different sized hydrocarbons (long chains that consist of hydrogen and carbon). This is useful as it means crude oil can be separated into more useful, purer products - such as petroleum (for cars), methane, propane and butane (for gas ovens and heaters in homes).
What do I need to know about fractional distillation? - MyTutor
However, alkanes with different length chains have different uses, so we need to separate the chains by length, which is what fractional distillation does.How does fractional distillation work?A common pattern in chemistry is that larger molecules have higher boiling points than smaller ones. Alkanes are no exception: the longer the chain, the ...

What is crude oil and how does fractional distillation work?
The mixture of compounds in crude oil is separated into more useful fractions by fractional distillation. The molecules with a lower molecular weight, such as butane, is separated first as a gas. This is because it requires less heat energy to evaporate.

How does fractional distillation work? - MyTutor
A fractional distillation column is heated at the bottom and gets progressively colder as you move up the column. The crude oil is heated so that the liquid evaporates to become gas. Molecules which are bigger have higher boiling points so condense back to liquid nearer the bottom of the column whereas smaller molecules have lower boiling ...
What is fractional distillation and how does it work. - MyTutor
What is fractional distillation and how does it work. Fractional distillation uses a fractional distillation tower, split into different layers each with a different temperature. It is used to sperate crude oil into the many different fuels used commonly in everyday use and it is also commonly used to seperate liquified air.
Explain Fractional Distillation (6 Marks) - MyTutor
Fractional distillation is the process of separating the different hydrocarbon compounds within crude oil (Show understanding of fractional distillation through context) . First the crude oil is heated/vaporised at around 35 0 C(1st Mark) and fed into a fractionating column which has a temperature gradient, meaning that Its hotter at the bottom ...
