| titleOfInvention | A kind of preparation method of dichloroalkane |
| abstract | The invention discloses a method for preparing dichloroalkanes. Diols, catalysts and solvents are mixed and heated up with stirring; HCL gas is introduced into the mixture to carry out reflux reaction for 3-5 hours; The liquid is treated to obtain dichloroalkanes. In the preparation method provided in the present invention, the addition of the catalyst ammonium chloride obviously speeds up the reaction speed and reduces the generation of side reactions; adding a large amount of solvent water in the reaction process can effectively suppress the by-product of monochloroether on the one hand The water phase can be directly applied repeatedly, and there is basically no sewage discharge; the use of the oil-water separator can effectively separate the dichloroalkane products, with high product purity and high yield. |
