  在砷酸催化剂存在下通过直接酯化二元膦酸合成烷基和芳基膦酸单酯

  摘要：

  二酯的部分水解、一氯单酯的水解或膦酸酐的醇解通常用于制备烷基-和芳基膦酸的单酯。已经报道了将二元膦酸酯化生成单酯的有限案例，这些方法都没有制备羧酸酯的类似方法那么简单，其中羧酸在存在下用醇酯化一种酸催化剂。描述了在催化量的苯胂酸存在下通过与醇直接酯化制备烷基-和芳基膦酸单酯的方法。在反应过程中形成的水​​被共沸除去。例如，甲基膦酸以良好的收率酯化得到其异丙基、丁基、环己基、冰片基和十八烷基单酯。类似地制备了苯基膦酸的乙基、丁基、己基和2-（乙硫基）乙基单酯，以及乙基膦酸2-异丙氧基乙基氢酯和苄基膦酸2-甲氧基乙基氢酯。

  The object of the present invention is to provide a highly crystalline polyethylene-2,6-naphthalate composition by achieving high molecular weight of PEN, wherein the polyethylene-2,6-naphthalate composition has greatly improved blow moldability and provides molded products having excellent hue, excellent weathering resistance, and additionally excellent transparency. The above-mentioned problems can be solved by a polyethylene-2,6-naphthalate composition comprising a specific phosphoric acid which is a phosphorus compound, cobalt element derived from a cobalt compound, manganese element derived from a manganese compound, and antimony element derived from an antimony compound, wherein the content of each of the elements simultaneously satisfies the following expressions (1) to (4): 10≤Co≤30mmol% 0.50≤P/Mn≤1.28 10≤Sb≤25mmol% 0.60≤IV≤1.50dL/g

  本发明的目的是通过实现 PEN 的高分子量来提供一种高结晶性的聚 2,6-萘二甲酸乙二酯组合物，其中聚 2,6-萘二甲酸乙二酯组合物大大提高了吹塑成型性，并提供具有优异色调、优异耐候性和优异透明度的成型产品。上述问题可以通过一种聚 2,6-萘二甲酸乙二醇酯组合物来解决，该组合物包含特定的磷化合物磷酸、从钴化合物中提取的钴元素、从锰化合物中提取的锰元素和从锑化合物中提取的锑元素，其中每种元素的含量同时满足以下表达式（1）至（4）：10≤Co≤30mmol% 0.50≤P/Mn≤1.28 10≤Sb≤25mmol% 0.60≤IV≤1.50dL/g
