| Physical and Chemical Properties | Petroleum ether is also called petroleum essence. Petroleum products with a distillation range of 35 to 80 °c. The main components are pentane and hexane. It is a colorless volatile liquid with kerosene odor. Specific gravity 0.635~0.660, boiling point 40~80 ℃, freezing point <-73 ℃. Steam is narcotic, a large number of inhalation can make people Coma or even asphyxia. Insoluble in water, soluble in anhydrous alcohol, benzene, chloroform, ether, oil, etc. Mainly used as solvent and oil extraction agent (6# solvent oil). It is highly flammable when exposed to fire, and is a Class I flammable liquid. Flash point: -50~8.5 ℃, spontaneous ignition point: 246~287 ℃, explosion limit: 1.1~6%, minimum ignition energy: 0.2-0.5 MJ. When flowing, it can be charged, and the resistivity is 8.4 × 1014 Ohm · cm. During storage, fire management shall be carried out according to class a fire hazard, and anti-static shall be paid attention. Fire, can be used foam, dry powder, carbon dioxide, 1211 and other fire extinguishing agents. Chemical reagent petroleum ether has 3 kinds of boiling range -30~60 ℃; 60~90 ℃ and 90~120 ℃, for different molecular weight of alkane mixture, used as solvent. |

| purification and water removal methods | petroleum ether is a light petroleum product and a mixture of low molecular weight alkanes. The boiling range is 30~150 ℃, and the temperature range collected is generally about 30 ℃. There are petroleum ethers with boiling range specifications of 30~60 ℃,60~90 ℃ and 90~120 ℃. It contains a small amount of unsaturated hydrocarbons, the boiling point is similar to that of alkanes, and it cannot be separated by distillation. The refining of petroleum ether usually washes the petroleum ether with its volume of concentrated sulfuric acid for 2-3 times, and then washes with a saturated solution prepared by adding 10% sulfuric acid to potassium permanganate until the purple in the water layer no longer disappears. Then it is washed with water, dried by anhydrous calcium chloride and distilled. If you need absolutely dry petroleum ether, you can add sodium wire (same as purified anhydrous ether). |
| use | solvent. Detergent. Extractant. Development agents for chromatographic analysis, etc. used as solvent and organic solvent for chromatographic analysis used as organic solvent and solvent for chromatographic analysis used as organic high-efficiency solvent, pharmaceutical extractant, fine chemical synthesis additive, etc. used in organic synthesis and chemical raw materials, such as preparing synthetic rubber, plastic, nylon monomer, synthetic detergent, pesticide, etc., is also a good organic solvent |
| production method | 1. industrial petroleum ether contains impurities such as unsaturated hydrocarbons, aromatic hydrocarbons, sulfides, acidic substances and non-volatile substances. When refining, wash with concentrated sulfuric acid (98% ~ 99%) until the color disappears, then wash with alkali and water in turn, dry with dehydrating agent and rectify. You can also wash the petroleum ether with a saturated solution of potassium permanganate dissolved in 10% sulfuric acid after washing with concentrated sulfuric acid until the purple in the water layer no longer disappears. Then wash with water, dehydrating agent drying and distillation. Used as dehydrating agent are anhydrous sodium sulfate, phosphorus pentoxide, metal sodium and calcium chloride. 2. Using solvent oil as raw material, washed with concentrated sulfuric acid, 20% sulfuric acid solution containing 0.1mol/L potassium permanganate, 10%-15% alkali solution and distilled water in turn to remove aromatic hydrocarbon compounds, olefin compounds, free acid brought in by pickling and free alkali brought in by alkali washing respectively. Then carry out rectification, remove a small amount of head liquid, according to the required boiling range to collect the fraction, that is, the petroleum ether finished product. |
