Description

Technical Field

[0001] The utility model relates to the technical field of condensation reaction, and more specifically, to a condensation reaction device. Background Art

[0002] A condensation reaction is a reaction in which two or more organic molecules interact with each other and are combined into a large molecule by covalent bonds, often accompanied by the loss of small molecules. Carbonyl compounds such as aldehydes, ketones or carboxylic acid derivatives form new carbon-carbon bonds next to the carbonyl group, thereby combining the two molecules. These reactions are usually carried out under the catalysis of acids or bases.

[0003] After searching, the utility model patent with the announcement number CN215087146U discloses a condensation reaction device of o-aminophenyl ether, including a base, a reaction barrel is provided on the upper end surface of the base, a scraping mechanism for side wall adhesives is provided in the reaction barrel, a barrel cover is provided on the upper end surface of the reaction barrel, a stirring mechanism is provided on the lower end surface of the barrel cover, a power mechanism for the stirring mechanism is provided on the upper end surface of the barrel cover, a discharge port is provided through the lower end surface of the reaction barrel, the scraping mechanism includes a rotating column rotatably connected to the bottom of the reaction barrel, a scraping plate is fixedly connected to the outer side wall of the rotating column, a slot is provided on the upper end surface of the rotating column, and the stirring mechanism includes two rotating rods rotatably connected to the lower end surface of the barrel cover; the patent has a reasonable structural design, which can not only improve the reaction efficiency of the condensation reaction and reduce the reaction time; but also can directly scrape the inner wall of the reaction barrel after the reaction is completed, so as to facilitate the cleaning of the inner wall of the reaction barrel.

[0004] However, the above patents still have the following shortcomings: the inner wall of the reaction barrel can only be cleaned by the scraper plate after the stirring mechanism is taken out, which is inconvenient; in addition, after the stirring mechanism is placed in the reaction barrel through the barrel cover, the stirring blade is fixed in one place for rotation, so that the stirring depth of the stirring blade for stirring the solution is limited, thereby reducing the effect of the condensation mixing reaction of the solution in the reaction barrel. For this reason, we propose a condensation reaction device. Utility Model Content
