Anhydrous sodium acetate crystal and its production method

摘要

PROBLEM TO BE SOLVED: To provide anhydrous sodium acetate crystal having a large bulk density and an efficient method for producing the same. An anhydrous sodium acetate crystal having an average particle size of 100 to 500 μm and a bulk density of 0.75 g / mL or more. A mixture of anhydrous sodium acetate and water having a volatile fraction of 1.0 to 6.0% and a bulk density of 0.4 to 0.73 g / mL is heated at 58 to 90 ° C. and stirred with a volatile fraction of 2 Obtained by a manufacturing method that dries to less than 0.0% by weight.
