      Based on the low quality of nonanedioic acid commodities domestically and the urgent need for importing high level nonanedioic acid (electron grade commodity), XJIPC has developed the preparation technology for high purity nonanedioic acid and authorized 3 nation-level patents.

      After the separation and purification of nonanedioic acid commodities manufactured by domestic factories, which are composed of total biprotic acid weighing greater than 95 percent and among which 88 percent is nonanedioic acid, more than 99 percent purity nonanedioic acid was obtained. The prepared commodities can be completely ranked in electron grade and replace the commodities overseas completely no doubt.
