Description

Technical Field

[0001] The utility model relates to the technical field of butyl acetate production equipment, and more specifically, to a vertical neutralization tank for butyl acetate production. Background Art

[0002] Butyl acetate is an organic compound. It is an acetate ester, usually formed by the reaction of butanol and acetic acid under the action of an acid catalyst. Butyl acetate is a colorless liquid with a fruity aroma. It is often used as a fragrance and solvent and is widely used in industries such as cosmetics, food, pharmaceuticals, and coatings.

[0003] Vertical neutralization tank is a kind of equipment used for neutralization reaction, usually used in industrial production. Its structure is similar to a vertical container with a stirring device inside, which is used to mix acidic and alkaline substances for neutralization reaction.

[0004] The existing vertical neutralization tank still has the following problems: the existing vertical neutralization tank often needs to use a stirring device when neutralizing butyl acetate in production, but the existing stirring device mostly uses a single stirring rod for horizontal stirring, and its stirring efficiency is not ideal. It takes a lot of time to stir to achieve a good neutralization effect, which undoubtedly reduces the neutralization efficiency;

[0005] And in the neutralization process, the internal neutralization temperature plays a very important role, but the temperature regulation inside the existing neutralization barrel is poor, which can easily affect the reaction rate and the purity of the product, causing great trouble to the use, and it is also cumbersome to clean the neutralization barrel, requiring personnel to flush and clean the inside, which not only has low cleaning efficiency, but also has unsatisfactory cleaning effect.

[0006] In view of this, we propose a vertical neutralization tank for butyl acetate production. Utility Model Content
