Barium stearate synthesis

1synthesis methods
A production method for barium stearate. The production method comprises the following steps: 1) adding water into a reactor and starting stirring and heating; 2) with water as a reaction dispersion medium and under the conditions of stirring and heating, adding powdery barium hydroxide at normal pressure so as to form a barium hydroxide suspension, then adding subparticle stearic acid while stirring when temperature reaches 50 to 60 ℃, stopping heating when temperature reaches 65 to 66 ℃ and carrying out a reaction for 20 to 30 min when temperature rises to 69 to 70 ℃ caused by reaction exotherm; and 3) subjecting a reaction product to filtering separation, drying and crushing so as to obtain a barium stearate product.

Yield:-

Reaction Conditions:

with barium(II) hydroxide in methanol;water at 65; for 0.000833333 h;Industrial scale;

Steps:

7 Example 7 Preparation of barium stearate
Preparing a solution of stearic acid in methanol in a container, The concentration is 0.4mol/L, the flow rate of the metering pump is set to 20ml/min; in another container, the aqueous solution of barium hydroxide is prepared at a concentration of 0.2mol/L. Set the flow rate of the metering pump to 20ml/min; start two metering pumps and enter the microchannel reactor or pipeline reactor at 65 degrees.The reaction was carried out for 3 seconds, then passed through a 20-degree cooling pipe, cooled, and the product was filtered, dried, and the product purity was 99.7%, and the particle diameter D50 was 0.32 μm. Or, after the above reaction, without cooling, Spray drying was carried out directly to obtain a product having a purity of 99.2% and a particle diameter D50 of 95 nm.
