The acidity and aggressive properties of volatile distillates in the synthesis of polyethylene terephthalate from ethylene glycol and dimethyl terephthalate have been studied on industrial technological lines. It has been shown that the acidity of the distillates increases as the synthesis process approaches completion. The composition of some of the acidic impurities in the distillates has been identified. It has been shown that the aggressive properties of distillates are determined by their content of strong acids. |
