Title:
PREPARATION METHOD FOR BISPHENOL PHOSPHATE HYDROXYL ALUMINUM SALT NUCLEATING AGENT
Document Type and Number:
WIPO Patent Application WO/2021/073070
Kind Code:
A1
Abstract:
The present invention relates to a preparation method for a bisphenol phosphate hydroxyl aluminum salt nucleating agent, comprising: an organic aluminum alkoxide is used as a raw material to prepare a bisphenol phosphate hydroxyl aluminum salt; first, bisphenol phosphate and sodium hydroxide are subjected to a neutralization reaction to prepare a bisphenol phosphate sodium salt; then the bisphenol phosphate sodium salt and an inorganic aluminum salt are subjected to a double decomposition reaction to prepare the bisphenol phosphate hydroxyl aluminum salt. A two-step reaction is replaced by the one-step reaction of phosphate and the organic aluminum alkoxide so as to synthesize the bisphenol phosphate hydroxyl aluminum salt. The present invention simplifies a production process, improves production efficiency, shortens a reaction time, and improves the quality of a product. Moreover, by means of the preparation method of the present invention, no salt-containing wastewater is generated during production, and the production process is environmentally friendly.
