Abstract

The invention discloses a rectification purification device for 9-bromoanthracene. The rectification purification device for 9-bromoanthracene comprises a rectification tower, and a first communicating pipe and a second communicating pipe which communicate with the rectification tower, a feeding pipe and a rotating mechanism; one end of the first communicating pipe is fixedly provided with a condenser, and one end of the second communicating pipe is fixedly provided with a reboiler; the feeding pipe is fixedly mounted on one side of the rectification tower, and a mounting block is connected to one side of the feeding pipe in a clamped mode; and the rotating mechanism comprises a rotating shaft vertically arranged in the rectification tower, a mounting plate used for mounting the rotating shaft is fixedly arranged in the rectification tower, and a plurality of blades are fixedly mounted on the rotating shaft. According to the invention, the phenomenon of flooding caused by overhigh flow rate of gas in the rectification process is avoided, so that the rectification operation can be normally carried out, the extracted purity is sufficient, and the quality after rectification and purification is improved.

Description

technical field

[0001] The invention relates to the technical field of rectification and purification, in particular to a 9-bromoanthracene production process and a rectification and purification device used therein. Background technique

[0002] 9-Bromoanthracene is an intermediate in the synthesis of 9-substituted derivatives of polycyclic aromatic hydrocarbon anthracene, white to light yellow crystalline powder. Melting point 97-100℃, soluble in acetic acid; carbon disulfide, 9-bromoanthracene is a fluorescent and phosphorescent material with excellent performance, widely used in the fields of optics, cosmetics, electronics, semiconductors and electroluminescent materials.

[0003] In the process of the production and preparation of 9-bromoanthracene, an important process is rectification and purification, which can improve the purity of 9-bromoanthracene prepared, but in the current rectification and purification device, there is no device that can control the flow rate ...
