| use | 1, 3-dichloropropene is a colorless and sweet volatile liquid, white or amber when impure, and can be used as an intermediate in organic synthesis. 1, 3-dichloropropene is an intermediate of the herbicide Yanyanwei, and is also a component in the soil fumigant drop mixture. Used as an intermediate in organic synthesis. Night can be used as a component of the dripping mixture, which has a strong nematicidal effect. A mixture of 1,3-dichloropropene 50-60%, 1,2-dichloropropane 25% and other chloride 15% is generally used. The mixture is a yellow-brown liquid with a pungent chlorine odor, which is corrosive and easy to absorb water. 1, 3-dichloropropene is also used in the synthesis of the herbicide Qingyanling. used to produce pesticides, herbicides, etc. |
| production method | is obtained by the reaction of propylene and chlorine. The reaction is carried out at 500-550°C and is obtained by separation. In the process of high temperature chlorination of propylene to epichlorohydrin, the side reaction makes the reactant a mixture of chlorinated hydrocarbons. During the separation of chloropropene, 3-chloropropylene-1 was obtained at the top of the tower, and by-product drops of mixture were obtained in the tower kettle, in which dichloropropane and dichloropropene reached more than 80%. Production of 1t epichlorohydrin, can produce by-product drops of 230kg mixture. the preparation method is obtained by reacting propylene and chlorine at 500~550 ℃ and separating. When propylene is chlorinated to prepare epichlorohydrin, the side reaction produces 3-chloropropene, 1, 3-dichloropropene and 1, 2-dichloropropane, which can also be generated after separation. The reaction equation is shown in the figure: CH3CH = CH2 + Cl2 → CH2ClCH = CH2 + HClCH2ClCH = CH2 + Cl2 → ClCH = CHCH2Cl |
