Description

Technical Field

[0001] The utility model belongs to the technical field of tributyl citrate synthesis, and particularly relates to a tributyl citrate synthesis device for synthesizing citric acid based on esterification. Background Art

[0002] The tributyl citrate synthesis device for synthesizing citric acid based on esterification refers to an experimental or production device specifically used for synthesizing tributyl citrate through an esterification reaction. Tributyl citrate is a colorless transparent oily liquid, soluble in most organic solvents but insoluble in water, and is commonly used as a green plasticizer.

[0003] In the process of synthesizing tributyl citrate, the esterification reaction is a key step. This reaction is usually carried out under specific conditions, including using a catalyst (such as concentrated sulfuric acid or chitosan sulfate made from chitosan as a carrier of sulfuric acid), controlling the reaction temperature, and ensuring the full mixing of reactants. The purpose of the esterification reaction is to esterify citric acid with n-butanol to produce tributyl citrate.

[0004] When the traditional tributyl citrate synthesis device is in use, its stirring method is relatively single, resulting in a relatively long time consumed for stirring the tributyl citrate synthesis device, and it is impossible to quickly and evenly mix the materials inside the tributyl citrate synthesis device. In view of this, we propose a tributyl citrate synthesis device for synthesizing citric acid based on esterification. Content of the Utility Model
