PREPARATION METHOD FOR HIGH PURITY ANTIMONY TRIGLYCOLATE

摘要

The present invention relates to a method for manufacturing high-purity antimony triglycolate (ATG) from an antimony-containing compound (crude antimony oxide). More specifically, the present invention relates to a manufacturing method of ATG, which increases the efficiency by simplifying a process and can reduce manufacturing costs through the recycle of ethylene glycol. The manufacturing method of ATG comprises the steps of: making antimony trioxide react with ethylene glycol; filtering the same after adding a complexing agent to the produced reactant; crystallizing the filtered reactant; separating and drying the ATG crystallized product; and removing the impurities.
