Description

Technical Field

[0001] This utility model relates to the technical field of antimony glycol manufacturing equipment, specifically a distillation apparatus for producing antimony glycol. Background Technology

[0002] Antimony glycolate appears as white or bluish-white crystalline granules, is non-toxic and odorless, and decomposes upon contact with moist air. Antimony glycolate is a novel catalyst used in polyester polycondensation reactions. Compared to antimony trioxide and antimony acetate catalysts, it has the following advantages: high solubility and good dispersibility in ethylene glycol solutions; high antimony content and good activity, which can improve the production capacity of the equipment; the catalyst itself does not introduce new impurities, which can improve the internal quality of the chips and enhance their spinnability in subsequent processing. In existing antimony glycolate production technology, the most important step is distillation. However, after distillation, existing antimony glycolate distillation equipment leaves a layer of waste material at the bottom of the inner cavity of the distillation unit, which is difficult to clean, not only easily affecting product quality but also hindering subsequent maintenance.

This not only easily affects the quality of the product but also hinders subsequent maintenance. Therefore, we need to propose a distillation apparatus for producing antimony glycol.
