The product characteristics, development direction, and differences in the production process of oxidized paraffin soap compared to synthetic fatty acid production are as follows: Through production practice, it has been determined that the optimal oxidation temperature is 140-145°C, air velocity is 12-13 m/min, endpoint acid value is 90, saponification temperature is 100°C, the outlet temperature of the heat treatment tube furnace is 150-180°C, and the material residence time is 1 hour. The oxidized paraffin soap products obtained under these production conditions show significant advantages in the application of phosphate ore flotation compared to traditional products.
