| description | The invention belongs to the technical field of organic synthesis, and particularly discloses a preparation method and a reaction device of 2-pentylidene cyclopentanone, and the preparation method comprises the following steps: taking n-valeraldehyde and cyclopentanone as raw materials, taking cationic resin as a catalyst, and continuously reacting in a tubular reactor to obtain the 2-pentylidene cyclopentanone. The reaction device is formed by connecting a feeding pump, a reaction section, a cooling section and a receiving tank in series, wherein a back pressure valve is arranged on a pipeline between the cooling section and the receiving tank; the reaction section is made of a stainless steel pipe with the length of 4m and the inner diameter of 8mm, and is filled with a cationic resin catalyst; and the cooling section is made of a stainless steel pipe with the length of 4m and the inner diameter of 8mm. The method provided by the invention has the advantages of simple process, no use of solvent, small envir |
