The manufacturing method of white mineral oil
1. Introduction
White mineral oil is a common raw material for chemical production, widely used in various fields such as lubricants, solvents, cosmetics, medicine, etc. With the continuous growth of market demand, the manufacturing methods of white mineral oil have also become a hot research topic. This article will introduce a common method for producing white mineral oil
2、 Materials and Equipment
1 Materials: paraffin, sulfuric acid, sodium hydroxide, water, etc
2. Equipment: reactor, agitator, cooler, storage tank, etc
3、 Manufacturing steps
1 Wax oil mixing: Add paraffin and sulfuric acid in a certain proportion to the reaction vessel, heat to a certain temperature, and stir to mix evenly
2. Sulfonation reaction: Add sodium hydroxide aqueous solution to the reaction vessel, causing the hydrocarbon groups in the paraffin to react with sulfuric acid to form sulfonates
3. Neutralization reaction: Add a certain amount of water to the reaction vessel to react the sulfonate with sodium hydroxide to produce neutral sodium sulfonate
4. Washing and separation: Wash the reaction solution with water to remove unreacted raw materials and by-products, and obtain crude white mineral oil
5. Refinement and purification: Refine and purify the crude white mineral oil to remove impurities and obtain the finished white mineral oil
4、 Notes
1 Control the reaction temperature and time to avoid excessive sulfonation or neutralization, which may affect product quality
2. When washing and separating, it should be thoroughly stirred and allowed to stand to ensure product purity
During the refining and purification process, attention should be paid to controlling operating conditions to avoid a decrease in product quality
5、 Conclusion: Through the above steps, we can manufacture high-quality white mineral oil. In the actual production process, operational parameters should be adjusted according to specific needs and conditions to ensure product quality and output. At the same time, strengthen monitoring and management of the production process to ensure production safety and environmental protection. In summary, mastering the manufacturing methods of white mineral oil is of great significance for improving the self-sufficiency and market competitiveness of chemical production raw materials.
