Our Factory Supply Barium Petroleum Sulfonate with CAS number 61790 - 48 - 5 is a high - quality chemical product. Barium petroleum sulfonate is a type of metal sulfonate, which is obtained through a series of refining and chemical reaction processes from petroleum fractions.
Physical Properties: It is usually a viscous liquid with a pale yellow to brown color. It has good solubility in organic solvents such as petroleum ether, benzene, and toluene. The density of this product typically ranges from 0.9 to 1.1 g/cm³, and its kinematic viscosity at a specific temperature (e.g., 100°C) is within a certain range that can be adjusted according to different production requirements.
Chemical Properties: It has excellent chemical stability and anti - oxidation properties. The barium ions in it can play a role in neutralizing acidic substances and preventing corrosion. Its molecular structure contains both hydrophobic hydrocarbon chains and hydrophilic sulfonate groups, which endows it with good surface - active properties.
Lubricant Additive: It is widely used as a lubricant additive. In engine oils, it can form a protective film on the metal surface, reducing friction and wear between moving parts. This helps to improve the efficiency of the engine, extend the service life of the engine, and reduce energy consumption. In industrial lubricants for machinery such as gears and bearings, it also plays a vital role in ensuring smooth operation and reducing mechanical failures.
Rust Inhibitor: Due to its good anti - corrosion properties, it can be used as a rust inhibitor in metal processing and storage. It can be added to metalworking fluids, cutting oils, and anti - rust coatings to prevent metal from rusting and corrosion in humid or corrosive environments.
Emulsifier: In some emulsion systems, it can act as an emulsifier. For example, in the preparation of water - in - oil emulsions, it helps to disperse water droplets evenly in the oil phase, making the emulsion system more stable. This is useful in some industrial cleaning agents and cosmetic products.
As a Lubricant Additive: When using it as a lubricant additive, it should be added to the base oil in the appropriate proportion. The specific addition amount depends on the type of lubricant, the working conditions of the equipment, and other factors. Generally, the addition amount ranges from 1% to 10%. Before adding, ensure that the base oil is clean and free of impurities. Mix the barium petroleum sulfonate with the base oil thoroughly through mechanical stirring or other appropriate mixing methods to ensure uniform distribution in the lubricant.
As a Rust Inhibitor: When using it as a rust inhibitor in metalworking fluids or anti - rust coatings, it can be added directly during the production process. The addition amount is usually determined according to the anti - rust requirements and the type of metal substrate. For example, in water - based metalworking fluids, the addition amount may be around 3% - 8%. After adding, stir well to ensure that it is evenly dispersed in the medium.
As an Emulsifier: In the preparation of emulsion systems, first, dissolve the barium petroleum sulfonate in the oil phase. Then, under high - speed stirring, slowly add the water phase to form an emulsion. The ratio of the oil phase to the water phase and the amount of emulsifier need to be optimized according to the specific requirements of the emulsion system.
Automotive Engine Oil Application: A well - known automotive manufacturer was facing problems with engine wear and high - temperature oxidation in their engines. After adding our Barium Petroleum Sulfonate Cas 61790 - 48 - 5 to their engine oil formulation at a concentration of 3%, they conducted a long - term field test. The results showed that the engine wear rate was significantly reduced. The protective film formed by the additive on the metal surface effectively prevented direct contact between metal parts, reducing friction and wear. At the same time, the anti - oxidation performance of the engine oil was improved, and the service life of the engine oil was extended by about 20%. This not only reduced the maintenance cost of the engine but also improved the overall performance and reliability of the vehicle.
