Sometimes we have to separate a chemical compound from a mixture. We use different physical characteristics such as boiling point, polarity of compounds to separate chemical compounds from mixtures. But sometime we cannot obtain 100% pure compound after separating.
Removing water from a solid is also an example to separating compounds. Follwing chemical industries use separation methods to prepare their products.
Transferring of materials from one homogeneous phase to another is defined as separating of mixtures.
Petroleum is a complex mixture of alkanes, cyclo alkane and aromatic compounds. Crude oil is not worth until it is separated into different compounds such as petrol, diesel, kerosene and many more.
Crude oil contains thousands of compounds. Composition of crude oil is classified according to their range of boiling points. These hydrocarbons are separated on the basis of their molecular mass by fractional distillation.
Valuable materials may be mixed with dirt or waste. But we need to recover or separate that valuable material. Therefore we have to follow a specific separating method to recover that material from initial mixture.
Removing unwanted materials from a mixture will reduce the weight of mixtures. It is very important in transporting. So reducing weight will decrease the cost of transportation.
In distillation, boiling point is used to separate chemical compounds. The most industrial use of this is, petroleum refining process. Petroleum contains so many organic chemicals and they have boiling point values.
Some compounds dissolve very well in some solvents than another solvent.
