  Disclosed herein is a method for purification of dianhydrides comprising a substantial amount (10000 ppm or more) of at least one metal salt. In one aspect the method is useful for the purification of dianhydrides prepared by the reaction of a halophthalic anhydride with a metal carbonate and may be optionally catalyzed by a phase transfer catalyst. The purification of the dianhydrides may be accomplished by hydrolyzing the dianhydride metal salt mixture directly to a tetraacid with an inorganic acid, followed by separating the impurities from an aqueous phase, and subsequently heating the tetraacid to effect ring closure to form a purified dianhydride having less than 50 parts per million metal halide and lower levels of other residual impurities. In one aspect the method is highly effective in removing phase transfer catalyst impurities such as hexalkylguanidinium halides initially present in the dianhydride undergoing purification.

  本文揭示了一种用于纯化含有大量（10000 ppm或更多）至少一种金属盐的二酐的方法。在一个方面，该方法适用于通过卤酸酐与金属碳酸盐反应制备的二酐的纯化，并且可以选择性地由相转移催化剂催化。通过将二酐金属盐混合物直接水解为四羧酸，随后从水相中分离杂质，并随后加热四羧酸以实现环闭合形成纯化的二酐，其中金属卤化物含量低于50ppm，其他残留杂质水平也较低。在一个方面，该方法在去除最初存在于正在纯化的二酐中的相转移催化剂杂质（如己烷基胍盐）方面非常有效。
