Problems solved by technology

[0004] But, along with the reaction of dicyclopentadiene, colloid will be produced in the tower still of reaction tower, cause raw material loss, and the colloid in tower still also reduces the efficiency of heat conduction in reaction tower, causes the depolymerization of dicyclopentadiene rate and the yield of cyclopentadiene decreased

Abstract

The invention discloses a continuous production device and method for cyclopentadiene and auxiliaries thereof, belonging to the technical field of chemical equipment. A preheater in the device communicates with the middle part of a rectifying tower through a first pipeline; the top of the rectifying tower sequentially communicates with a first condenser, a first reflux tank and a first reflux pumpthrough a second pipeline, an outlet of the first reflux pump communicates with a first product output pipeline, and the middle part of the first product output pipeline communicates with the top ofthe rectifying tower through a third pipeline; the bottom of the rectifying tower communicates with a circulating pump through a fourth pipeline, the circulating pump communicates with a first pipeline located between the preheater and the rectifying tower through a fifth pipeline, and the middle part of the fifth pipeline communicates with the middle part of a regeneration tower through a sixth pipeline; and the top of the regeneration tower sequentially communicates with a second condenser, a second reflux tank and a second reflux pump through a seventh pipeline, the second reflux pump communicates with the first pipeline through an eighth pipeline, and the middle part of the eighth pipeline communicates with the top of the regeneration tower through a ninth pipeline. The device can improve the yield of cyclopentadiene.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a continuous production device and method for cyclopentadiene and its auxiliary agents. Background technique [0002] Cyclopentadiene can be used as a production raw material in the preparation of various chemical reagents. For example, it can undergo condensation reactions with aldehydes and ketones to generate fulvene derivatives. Cyclopentadiene can also react with transition metal salts to generate metallocene compounds. Currently, cyclopentadiene is mainly produced by cracking dicyclopentadiene. [0003] When cyclopentadiene is prepared by cracking dicyclopentadiene, it is necessary to mix dicyclopentadiene, diluent, and polymerization inhibitor and then add them to the reaction tower to cause cracking reaction of dicyclopentadiene to obtain cyclopentadiene . [0004] But, along with the reaction of dicyclopentadiene, colloid will be produced in the tower still...
