  • Patent number: 12084470
    Abstract: A method for preparing a bisphenol phosphate hydroxyl aluminum salt nucleating agent is provided, which adopts organic aluminum alcoholate as raw materials to prepare bisphenol phosphate hydroxyl aluminum salt. In prior art, a neutralization reaction of bisphenol phosphate and sodium hydroxide is firstly performed, so as to prepare bisphenol phosphate sodium salt; then a double decomposition reaction of sodium salt and inorganic aluminum salt is performed to prepare the bisphenol phosphate hydroxyl aluminum salt. The present invention combines the two-step reaction in prior art into the one-step reaction of phosphate and organic aluminum alcoholate for synthesizing the bisphenol phosphate hydroxyl aluminum salt, thereby simplifying the production process, improving the production efficiency, shortening the reaction time, and improving the product quality.
