Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a butanol and butyl acetate azeotrope separation device. Background technique [0002] Azeotrope refers to a homogeneous solution of two or more different components, the mixed solution has only one boiling point under a fixed pressure. [0003] Butanol and butyl acetate are two important solvents in the chemical production process. Due to the characteristics of the production process, butanol and butyl acetate are inevitably mixed together and must be separated. However, the azeotrope formed by the two is Ordinary distillation methods cannot separate it. [0004] At present, most factories use the method of adding alkali to butanol and butyl acetate solution to separate them. The reaction between alkali and butyl acetate can produce butanol and acetate solution, but the alkali will be solidified to form blocks during storage and use. When a batch of alkali is put in...

Problems solved by technology

[0003] Butanol and butyl acetate are two important solvents in the chemical production process. Due to the characteristics of the production process, butanol and butyl acetate are inevitably mixed together and must be separated. However, the azeotrope formed by the two is Ordinary distillation methods cannot separate them

[0004] At present, most factories use the method of adding alkali to butanol and butyl acetate solution to separate them. The reaction between alkali and butyl acetate can produce butanol and acetate solution, but the alkali will solidify and form blocks during storage and use. When a batch of alkali is put into the solution for reaction, it is easy to cause insufficient reaction between alkali and butyl acetate and affect the reaction rate, and the acetate solution formed in the rectification is easy to condense into solid and adhere to the inside of the reaction cylinder, which is not easy to clean
