Method for Producing Anhydrous Sodium Acetate Crystals and Anhydrous Sodium Acetate Crystals

摘要

To provide: an anhydrous sodium acetate crystal having a high bulk density; and a method for efficiently manufacturing the same.SOLUTION: An anhydrous sodium acetate crystal has a mean particle diameter of 100-500 μm and a bulk density of 0.75 g/mL or more. The anhydrous sodium acetate crystal is obtainable by a manufacturing method including heating a mixture of anhydrous sodium acetate having a volatile matter fraction of 1.0-6.0% and a bulk density of 0.4-0.73 g/mL and water at 58-90°C, and stirring and drying the mixture until the volatile matter fraction reaches less than 2.0 wt.%.SELECTED DRAWING: None
