Automatic ester-water separator for production of n-butyl acetate

Abstract

The invention discloses an automatic ester-water separator for n-butyl acetate production, which comprises a bottom plate, two groups of supporting plates are fixed on both sides of the top end of the bottom plate, an ester-water separator main body is fixed on the top ends of the supporting plates, a cooling jacket is fixed on the outer peripheral surface of the ester-water separator main body, and the cooling jacket is fixed on the top end of the bottom plate. A plurality of groups of main flow dividing pipes are mounted at the top end of the ester-water separator main body, the main flow dividing pipes are distributed at equal intervals in the horizontal direction of the cooling sleeve, ester phase pipe straight pipes are mounted at the top ends of the main flow dividing pipes, first bent pipes are mounted at the two ends of each ester phase pipe straight pipe, and the bottom ends of the first bent pipes extend into the ester-water separator main body. According to the invention, the flowing influence of the mixed liquid is reduced, the separator is maintained at a relatively low temperature, the influence of the temperature on ester and water is reduced, the ester-water separation quality of the separator is improved, the separator carries out ester-water separation in a full-load state, and the separation efficiency of the separator is improved.

Description

technical field [0001] The invention relates to the technical field of n-butyl acetate production and preparation, in particular to an automatic ester-water separator for n-butyl acetate production. Background technique [0002] N-Butyl Acetate is a colorless viscous liquid with a strong banana flavor. It naturally exists in most fruits and is a food flavoring that is allowed to be used in regulations. It is widely used in industrial processes such as medicine and petrochemical industry. It is also a good Industrial organic solvents. The catalysts currently used for ester synthesis mainly include cation exchange resins, solid superacids, heteropolyacids, and organic acids. Usually, concentrated sulfuric acid is used as a catalyst to synthesize acetic acid n-butanol by direct esterification of acetic acid and n-butanol. Butyl ester, this method has the disadvantages of corrosive equipment, many by-products, cumbersome aftertreatment, easy pollution of the environment, and low...
