  A process for making bis(aryloxyalkyl)terephthalates useful as antiplasticizers for thermoplastic polyesters is disclosed. Dimethyl terephthalate is reacted with an excess of an aryloxyalkanol in the presence of a condensation catalyst to produce an intermediate mixture comprising a bis(aryloxyalkyl)terephthalate, a mono(aryloxyalkyl)terephthalate, and unreacted aryloxyalkanol. This mixture continues to react at reduced pressure while unreacted aryloxyalkanol is removed and the mono-ester content is reduced to less than 1 mole % based on the combined amounts of mono- and bis-esters. Both steps are performed substantially in the absence of oxygen. Additional unreacted aryloxyalkanol is then removed to provide a purified bis(aryloxyalkyl)terephthalate having an overall purity of at least 98 mole % and a yellowness index less than 10. Careful control over catalysis, exposure to air, and other process conditions enables the preparation of high yields of bis(aryloxyalkyl)terephthalates that have low color and other valuable attributes. A method of producing bis(aryloxyalkyl)terephthalate articles having improved compressive strength is also disclosed.

  本发明揭示了一种制备双(芳氧基烷基)对苯二甲酸酯的方法，该方法可用作热塑性聚酯的抗增塑剂。将对苯二甲酸二甲酯与芳氧基烷醇的过量反应在缩合催化剂的存在下进行，以产生包括双(芳氧基烷基)对苯二甲酸酯、单(芳氧基烷基)对苯二甲酸酯和未反应的芳氧基烷醇的中间混合物。该混合物在减压条件下继续反应，同时去除未反应的芳氧基烷醇并将单酯含量降至小于基于单酯和双酯总量的1摩尔％。这两个步骤都在基本无氧的条件下进行。然后去除额外的未反应芳氧基烷醇，以提供具有总纯度至少为98摩尔％和黄度指数小于10的纯化双(芳氧基烷基)对苯二甲酸酯。对催化剂、暴露在空气中的控制以及其他工艺条件的精细控制可以实现高产率的低色双(芳氧基烷基)对苯二甲酸酯的制备。本发明还揭示了一种生产具有改善压缩强度的双(芳氧基烷基)对苯二甲酸酯制品的方法。
