2-Chloropropane - Nature
Open Data Verified Data
colorless liquid with pleasant odor. The relative density was 0. 850 (20 ℃). Freezing point -117 °c. Boiling point 35.4 °c. Refractive index 1.3811(15 °c),1. 377 (20 °c). Solubility in water: O ℃ is 0. 44%,10 ℃ is 0.362%, 12.5 ℃ is
344%. Soluble in methanol and ether. Because the chlorine atom in its structure is very active, it can react with aromatic amine and aliphatic amine to dehydrogen chloride to generate N-isopropyl aromatic amine and isopropyl aliphatic amine, and the chlorine atom is hydrolyzed to generate isopropyl alcohol.

| Application | 2-chloropropane is a fungicide, rust-killing Amine, fluoroamide, insecticide fenvalerate, fenvalerate, propoxur, herbicide, an intermediate of the phosphorus of sarcanthus. used as pesticide intermediates, organic synthesis raw materials, solvents, etc. used in organic synthesis organic synthesis raw materials, used in the preparation of pesticide toxicochlor, also used as solvent. use as solvent and in the production of isopropylamine. primary use as solvent and in the manufacture of isopropylamine |
| production method | results from the reaction of propylene with anhydrous hydrogen chloride. The dried hydrogen chloride is mixed with propylene in a molar ratio of 1:1.2, fed to a reactor containing an active clay catalyst, reacted at 120-140 ° C., and the product is condensed to give 2-chloropropane. The yield was 65%. It can also be obtained from the reaction of isopropanol with hydrogen chloride in the presence of zinc chloride. There are several preparation methods. (1) in the reaction bottle, isopropyl alcohol and zinc chloride catalyst are added, hydrogen chloride is introduced, and 2-chloropropane is obtained by reaction at an appropriate temperature, and the product is obtained by distillation. (2) the reaction between propylene and anhydrous hydrogen chloride is carried out in the presence of active soil catalyst. The dried hydrogen chloride and alkali-washed propylene enter the mixer at a molar ratio of 1: 1.2 and then enter the catalytic reactor, the reaction was carried out at 120-140 °c and the product was cooled to a finished product. |
