For chemical plants to produce ethyl acetate.
In the process of polyester production, the role of the Esterification tower is to separate the gas phase water and ethan glycol mixture generated during the esterization reaction process, separate the low-boiling water from the top of the tower, and separate the high-boiling ethylene glycol. Currency is condensed at the bottom of the tower, and ethylene glycol, as the main raw material for polyester production, can be re-recovered to reactors for reproduction.
Esterization reactions are a type of organic chemical reactions, which are divided into three types: carboxylic acid reacts with alcohol, or inorganic oxygenic acid reacts with alcohol, or inorganic strong acid reacts with alcohol. The esterization reaction of carboxylic acid and alcohol is reversible, and the general response is extremely slow, so concentrated sulfuric acid is often used as a catalyst. Multi-carboxylic acid and alcohol reaction can generate multiple esters. The reaction of inorganic acid and mellow is generally faster. The typical esterization reactions include the reaction of ethanol and acetic acid, and the generic acetate with aromatic smell is a raw material for manufacturing and medicine. The esterization tower are widely used in areas such as organic synthesis.
