Surface Treatment Methods for Industrial White Oil

Industrial white oil is a highly refined product with a slight petroleum odor when heated. It is insoluble in water and ethanol, soluble in volatile oils, and miscible with most non-volatile oils. It is stable to light, heat, and acids, but will gradually oxidize when exposed to light and heat for extended periods. What are its surface treatment methods? Here is a summary by the editor:

Steam process: Industrial white oil directly contacts dried white carbon black with organic vapor to produce the required reaction.

2. Reflux Method: Industrial white oil is boiled and mixed with white carbon black and the reaction solution to initiate the required reaction.

3. The Pressurized Heat Reaction Method: Industrial white oil, white carbon black, and reaction solution are subjected to high-pressure sterilization in a pressure vessel, thereby triggering a specific reaction. The specific chemical reaction involves: as the degree of hydration increases, isolated silanol groups gradually decrease, while adjacent silanol groups gradually increase. Adjacent silanol groups possess strong adsorption capabilities for water and substances.

If the solvent used in the extraction process of industrial white oil in food processing and production becomes contaminated after a series of production processes, and migrates into the food, it can cause contamination of the finished food products. Hope this information is helpful to you.
