| titleOfInvention | Continuous preparation method for producing chlorohydrocarbon from carbon tetrachloride and olefin |
| abstract | The invention discloses a continuous preparation method for producing chlorohydrocarbon by carbon tetrachloride and olefin, which comprises the following steps: (1) continuously adding iron powder or iron filler, catalyst auxiliary agent alkyl phosphate and carbon tetrachloride into a first ferrous complex catalyst preparation kettle; (2) conveying the material reacted in the step (1) to a second chlorohydrocarbon synthesis reaction kettle after quickly passing through a filter, and reacting with olefin continuously introduced into the chlorohydrocarbon synthesis reaction kettle; (3) and (3) introducing the crude halohydrocarbon obtained in the step (2) into a subsequent separation system, purifying and collecting the final target halohydrocarbon product. The invention separates the preparation of ferrous complex catalyst from the synthesis of chlorohydrocarbon, and avoids the reduction of catalytic activity of olefin self-polymer due to the adhesion of iron powder or iron filler. The method has simple process, further improves the reaction efficiency by controlling the temperature, time, pressure and the like of the reaction, and simultaneously ensures that the reaction product has higher yield and better selectivity. |
