C1 Fractional Distillation of Crude Oil

HideShow resource information
what is crude oil
a mixture of hydrocarbons
1 of 11
what is crude oil formed from
buried remains of plants and animals
2 of 11
what is a mixture
two or more elements or compounds that arent chemically bonded together
3 of 11
what happens to crude oil in the process of fractional distillation
split into separate groups of hydrocarbons
4 of 11
what is crude oil mostly a mixture of
hydrocarbon molecules
5 of 11
because it is a mixture what does this mean for the individual compounds
they all keep their original properties e.g. condensing points
6 of 11
how does this enable fractional distillation
the vaporised oil rises up the column and the various fractions are constantly tapped off at the different levels where they condense
7 of 11
what happens to viscosity as the chain of hydrocarbons get shrter
less viscous (runny)
8 of 11
what happens to volatility as the chain of hydrocarbons get shorter
more volatile (lower boiling point)
9 of 11
what happens to flammability as the chain of hydrocarbons gets shorter
more flammable (easier to ignite)
10 of 11
what are the products of crude oil
mostly alkanes
