  摘要：

  现已开发出一种简单有效的单芳基膦酸甲酯制备方法，该方法涉及在叔胺或环氧丙烷（1,2-环氧丙烷）存在下钯催化芳基碘化物与膦酸甲酯的偶联。 尽管膦酸甲酯具有热敏性和水解敏感性，但这一过程与各种官能团兼容，而且产率合理。对称取代的二芳基膦酸盐也可以用两个等量的芳基碘化物来制备。不对称取代的二芳基膦酸盐很容易通过已知的方法从单芳基膦酸盐中获得，或者通过钯催化第二个芳基碘化物的反应，而无需分离从甲基膦酸盐中得到的中间单芳基膦酸盐。

  This invention provides a polyester and a polyester molded product, which, while maintaining color tone, transparency, and thermal stability, can realize a high polycondensation rate, are less likely to cause the production of polycondensation catalyst-derived undesired materials, and can simultaneously meet both quality and cost effectiveness requirements, which can exhibit the characteristic features, for example, in the fields of ultrafine fibers, high transparent films for optical use, or ultrahigh transparent molded products. These advantages can be realized by using, in the production of a polyester in the presence of an aluminum compound-containing polyester polycondensation catalyst, an aluminum compound having an absorbance of not more than 0.0132 as measured in the form of an aqueous aluminum compound solution, prepared by dissolving the aluminum compound in pure water to give a concentration of 2.7 g/liter in terms of the amount of aluminum element, under conditions of cell length 1 cm and wavelength 680 nm.

  本发明提供了一种聚酯和聚酯成型产品，可以在保持色调、透明度和热稳定性的同时，实现高聚酯化速率，不太可能引起聚酯化催化剂来源的不良材料的生产，并且可以同时满足质量和成本效益的要求，这些优点可以在超细纤维、用于光学的高透明薄膜或超高透明成型产品等领域展现出特征性能。通过在含有铝化合物聚酯聚合催化剂的聚酯生产中使用具有吸光度不超过0.0132的铝化合物，可以实现这些优点。该吸光度是在细胞长度为1厘米，波长为680纳米的条件下，将铝化合物溶解在纯水中以给定铝元素量浓度为2.7克/升形成的水溶性铝化合物溶液中测量得出的。
