Polyester Polymerization Reactor

The polyester polymerization reactor is a reaction vessel used for synthesizing high‑molecular‑weight compounds, encompassing both esterification and polycondensation reactions. It is primarily employed in the fields of resin, rubber, plastics, and other high‑polymer materials. Esterification is a reaction in which alcohols react with carboxylic acids or inorganic oxygen‑containing acids under specific temperature and pressure conditions to produce esters and water; the water is condensed and collected after passing through a reflux column, while the alcohol is returned to the reactor. Polycondensation refers to a reaction in which one or more monomers undergo condensation to form a high‑molecular‑weight polymer. The primary product of this reaction is known as a polycondensate. During polycondensation, temperature and vacuum are gradually increased; the alcohol produced during the reaction is discharged from the reactor, condensed, and collected, ultimately leaving the polycondensate in the reactor. After the experiment is completed, the bottom discharge port is opened for operations such as material discharge, fiber drawing, and pellet cutting.
