| Use | organic synthesis intermediate, solvent. used in organic synthesis, solvent, etc. |
| production method | is obtained by chlorination of pentane. First, the pentane is dehydrated with hydrogen chloride, evaporated in the evaporator, and then mixed with chlorine gas at a pressure of 0.55MPA at a high flow rate of 2000 DM3 in a Venturi mixer made of raw iron, and the temperature is controlled at 50 ℃, the mixed gas is then fed to the reactor of the tubular evaporator. The molar ratio of pentane to chlorine was 15:1. The reactor temperature was 120 °c at the steam inlet and gradually increased to 300 °c. The product was immediately sent to a cooler for cooling to suppress the formation of dichloropentane. The product consisted of unreacted pentane, hydrogen chloride, chloropentane and a small amount of dichloropentane. After cooling and fractionation, the hydrogen chloride and pentane were removed, and the 1-chloropentane product was obtained. The other method is to react pentanol with hydrogen chloride, dissolve zinc chloride with hydrochloric acid, then add pentanol, reflux at 120 ℃ for 3H, and then distill, the 106-109 °c fraction was collected as the finished product. |
