Properties and stability

1. Use and store according to specifications. It will not decompose and avoid contact with oxides.

2. Easily soluble in water and insoluble in ethanol. When barium acetate is recrystallized with water, the precipitated crystals are trihydrate when the temperature is below 24.7°C. The precipitated crystals are monohydrate at 24.7~41℃. The crystals precipitated above 41℃ are anhydrous. At 0°C, 100g of water can dissolve 59g of barium acetate. At 24.1℃, 78.1g of barium acetate can be dissolved in 100g of water. At 100℃, 75g of barium acetate can be dissolved in 100g of water. Used as a catalyst for organic reactions such as olefin polymerization.

Storage method

This product should be kept sealed.

Synthesis method

1. When barium acetate monohydrate is recrystallized with water, the crystals precipitated when the temperature is kept above 41°C are anhydrous barium acetate.

2. Anhydrous barium acetate can also be obtained by heating barium acetate monohydrate at 170°C for 12 hours while isolating carbon dioxide gas.

3.Prepared from the reaction of barium sulfide or barium hydroxide and acetic acid.


1. Analysis of calcium. Precipitating agent for sulfates and chromates.

2. Catalyst for organic reactions. Mordant. lubricating oil.

3.Used as analytical reagents, such as precipitants and organic reaction catalysts.
