There are several uses of petroleum ether:
1. It is mainly used as solvent and oil extraction.
2. Used as organic solvent and chromatographic analysis solvent; It is used as organic high-efficient solvent, pharmaceutical extractant, fine chemical synthesis assistant, etc; It can also be used in organic synthesis and chemical raw materials.
3. It is used for organic synthesis and chemical raw materials, such as synthetic rubber, plastic, nylon monomer, synthetic detergent, pesticide, etc. it is also a good organic solvent. It is mainly used as a solvent, as a foaming agent for foamed plastics, and as an extractant for drugs and essence.
Petroleum ether can be divided into three types according to the boiling points during preparation, which are 30-60 ℃, 60-90 ℃ and 90-120 ℃.
Petroleum ether 30-60 ℃ means that the initial boiling point of the distillate is not lower than 30 ℃ and the final boiling point is not higher than 60 ℃. By analogy, 30-60 petroleum ether is the most volatile, 60-90 is the second, and 90-120 is relatively less volatile.
