Useful products from crude oil

A brief over-view of the separation of oil into useful products

Beware: The commentary confusingly treats alcohols such as methanol as if they were derived directly from crude oil. It doesn't make clear that alcohols can only be produced by further reactions of fractions from the distillation. YouTube

Fractional distillation of crude oil

Lab and industrial fractionation of crude oil. Generally good, but there are problems. The molecular models used are awful - try to pick out what is wrong with them. There is also a lot of cheating going on in the first lab demonstration - there is no way they could collect the volumes shown from the tiny bit of crude oil they started with. And don't worry too much about the temperatures quoted in the column - almost every source you look at quotes different temperatures! YouTube
