4. Distillation has a high vacuum, which can reach below 0.1 pa. It can obtain a high vacuum inside. Molecular distillation is usually carried out at a very low pressure. The material is not easily oxidized and damaged by operation. 5. Distillation liquid film is thin, heat transfer efficiency is high, film thickness is less than 0.5 mm. 6.

A hydrocarbon is a covalently bonded compound consisting of carbon and hydrogen atoms only. Some hydrocarbons only have a few carbon atoms in each molecule, others can have over 70 carbon atoms. There are 2 ways of drawing the formula of an organic compound – 1. Molecular formula tells us the actual number of each atom, e.g. CH4 or C2H4 2.

However, fractional distillation gave us 100% ethyl acetate in the first fraction. Even though, simple distillation gave us pure butyl acetate, it failed to give pure ethyl acetate. Thus, it can be successfully concluded that fractional distillation was a far more efficient way of separating the mixture than simple distillation.
