Embodiment 1
[0029] The production method of barium stearate described in this embodiment is carried out according to the following steps:
[0030] 1) In a 5000ml flask with heating, stirring and temperature measuring devices, add 1200ml of water to start stirring and heating;
[0031] 2) Under normal pressure, using water as the reaction dispersion medium, while stirring and heating, first add powdered barium hydroxide octahydrate (Ba(OH)) to the flask in step 1) 2 ·8H 2 O) 132.0g, stir evenly to form a barium hydroxide suspension; when the temperature reaches 58℃, add 222.2g of stearic acid while stirring, stearic acid is fine granular industrial stearic acid; when the temperature reaches At 66°C, the heating was stopped; the temperature was further increased due to the exotherm of the reaction, and the reaction was maintained at 70°C for 30 minutes; the reaction ended. The barium hydroxide octahydrate is powdered barium hydroxide octahydrate with an industrial-grade purity greater than 98%. ...
Embodiment 2
[0035] The production method of barium stearate described in this embodiment is carried out according to the following steps:
[0036] 1) In a 5000ml flask equipped with heating, stirring and temperature measuring devices, add 1200ml of the circulating mother liquor obtained in Example 1 and heat while stirring, and then start stirring and heating;
[0037] 2) Under normal pressure, with water as the reaction dispersion medium, while stirring and heating, first add 132.1g of powdered barium hydroxide octahydrate to the flask in step 1), and stir evenly to form a barium hydroxide suspension Turbid liquid; when the temperature reaches 56°C, add 222.05g of stearic acid while stirring. Stearic acid is a fine granular industrial grade stearic acid; when the temperature reaches 65°C, stop heating; due to the exothermic reaction The temperature rose further, maintained at 69°C, and reacted for 30 minutes; the reaction ended. The barium hydroxide octahydrate is powdered barium hydroxide o...
