| titleOfInvention | Preparation method of 1-chlorine-3-phenyl propane |
| abstract | The invention provides a preparation method of 1-chlorine-3-phenyl propane. Thionyl chloride, serving as a chlorinating agent, and 3-phenylpropanol have a chlorine substitution reaction with pyridine as a catalyst. The chlorine substitution reaction is conducted under the condition that the reaction temperature ranges from 50 DEG C to 90 DEG C, crude products obtained through the chlorine substitution reaction are cooled and crystallized, supernatant liquid is neutralized through alkali liquor, an oil layer is separated out and subjected to vacuum distillation under the pressure of -0.098 MPa, cut fraction obtained at the temperature of 97 DEG C to 98 DEG C is collected, and 1-chlorine-3-phenyl propane is obtained. The percentage of 3-phenylpropanol residues in the product obtained through the method is 0.1% or lower, and the conversion rate is high. Meanwhile, the pyridine catalyst can be cooled, crystallized and recycled in reaction products in the form of hydrochloride, the catalyst can be infinitely recycled, the use amount of the catalyst is greatly decreased, and cost is saved. |
