Sulfurized isobutylene is an important organic compound. Lubricating oil additives are important components for improving lubricating oil performance. Among them, sulfurized isobutylene is an additive that has attracted much attention. So, what is the lubricant additive sulfurized isobutylene? What are its functions and classifications?
Preparation of sulfide isobutylene
Isobutylene sulfide is an organic compound with the molecular formula C12H16S. It has various functions such as antioxidant, anti-wear, condensation reducing, cleaning, etc., so it has wide application value in the field of lubricating oil additives. As an important additive, sulfurized isobutylene can significantly improve the performance of lubricants and extend the service life of equipment.
Sulfated isobutylene is produced by reacting isobutylene with hydrogen sulfide under the action of a catalyst. The reaction principle is as follows:
CH2=C(CH3)2 + H2S → CH2=C(CH3)CH2SH
The process flow mainly includes the following steps: First, isobutylene and hydrogen sulfide are pretreated respectively, then reacted under the action of a catalyst, and finally the product is separated and refined. Preparation conditions include appropriate temperature, pressure and catalyst type.
Types and functions of vulcanized isobutylene
anti-oxidation
Sulfated isobutylene has excellent antioxidant properties, which can inhibit oxidation of lubricating oil and extend the service life of the oil. By inhibiting oxidation reactions, sulfurized isobutylene can reduce the acid value of lubricating oils and prevent oils from thickening and deteriorating.
wear resistant
Vulcanized isobutylene has anti-wear effects, which can effectively reduce friction and wear of mechanical equipment and improve equipment operating efficiency. Its anti-wear effect is mainly achieved by forming a protective film on the metal surface, thereby reducing the friction coefficient and reducing wear.
Decreased condensation
Sulfated isobutylene has the effect of lowering the freezing point of lubricating oil and maintaining the fluidity of lubricating oil under low temperature conditions. This is useful for equipment used in cold areas or at high altitudes to ensure proper operation of the equipment.
clean
Sulfurized isobutylene also has a cleaning effect, preventing the formation of deposits or dirt in the lubricant. These deposits or dirt will affect the fluidity and lubrication effect of the lubricating oil, so cleaning is very important to keep the equipment in good operating condition.
Development prospects
With the continuous improvement of environmental awareness, the requirements for environmental protection, efficiency and economy of vulcanized isobutylene are also getting higher and higher. Therefore, seeking more environmentally friendly and efficient preparation methods and application fields has become an important direction for the development of vulcanized isobutylene.
