• METHOD FOR PREPARING QUATERNARY PHOSPHONIUM SALTS
  申请人：Microvast Power Systems Co.,Ltd.

  公开号：US20150166587A1

  公开（公告）日：2015-06-18

  A two-step pathway for preparing high pure quaternary phosphonium salts is disclosed. In the first step, hydrogen phosphide (PH 3 ) or a higher phophine reacts with a protonic compound to produce a phosphonium salt, which then reacts with a carbonic acid diester to produce a quaternary phosphonium salt in the second step. On one hand, hydrogen phosphide (PH 3 ) and higher phophines, including primary phosphines, secondary phosphines, and tertiary phosphines, after neutralization with protonic compound, become sufficiently reactive and can be alkylated by carbonic acid diester to form quaternary phosphonium cations. On the other hand, as an anion-exchange procedure is completely avoided, the process not only gives quaternary phosphonium salts of high purity, but also gives people freedom to design the cation and the anion of a quaternary phosphonium salt synchronously by choosing a preferred phosphine and a protonic compound that can supply a desired anion.

  揭示了一种制备高纯度四元磷铵盐的两步途径。在第一步中，氢磷化物（PH3）或更高的磷化物与质子化合物发生反应，产生磷铵盐，然后在第二步中与碳酸二酯发生反应，产生四元磷铵盐。一方面，氢磷化物（PH3）和更高的磷化物，包括一次磷化物、二次磷化物和三次磷化物，在与质子化合物中和后变得足够活性，可以被碳酸二酯烷基化形成四元磷铵阳离子。另一方面，由于完全避免了阴离子交换程序，该过程不仅提供高纯度的四元磷铵盐，还使人们可以通过选择理想的磷化物和可以提供所需阴离子的质子化合物，同时设计四元磷铵盐的阳离子和阴离子。
