Stearic Acid → Lead stearate

Participants

Reaction Steps

A 500-ml capacity beaker was charged with 147 g of stearic acid and it was molten at 160°±5° C. in an oil bath under agitation by a glass vane, and 57.74 g of the lead monoxide powder (Sample A-6) and 0.31 g of powdery hydroxylamine sulfate were gradually added to the melt to effect reaction. Then, aging was conducted for 15 minutes to obtain a melt of lead stearate. The melt was poured into a watch glass and naturally cooled. The resulting solid was pulverized by an atomizer to obtain a lead stearate powder (Sample 2-7).
