Introduction: The importance of lubricating oil additives
Lutensils play a crucial role in modern industry and transportation. It can not only reduce friction between mechanical components and extend the service life of the equipment, but also improve the efficiency of the system and reduce energy consumption. However, with the advancement of technology and the increasingly stringent environmental protection requirements, traditional lubricating oils can no longer meet the needs of high-performance mechanical equipment. Therefore, the development of efficient and environmentally friendly lubricant additives has become a hot research direction.
Lutrient oil additives are chemicals that improve or impart specific properties to the lubricant by adding to the base oil. These additives can significantly improve the key performance indicators of lubricating oils such as oxidation resistance, wear resistance, corrosion resistance, and clean dispersion. For example, engines operating in high temperature and high pressure environments may cause serious mechanical failures due to insufficient lubrication if they do not have suitable additives; while in cold winters, appropriate additives can help lubricant maintain good fluidity and ensure the engine Started smoothly.
In recent years, with the increasing demand for high-performance lubricants, researchers have begun to focus on new additives, especially those with unique molecular structure and excellent properties. Among them, 2-isopropylimidazole (2-IPMI) as a potentially efficient lubricating oil additive has gradually attracted widespread attention. 2-IPMI is unique in that its molecules contain an imidazole ring and an isopropyl side chain. This structure gives it excellent polarity and reactivity, allowing it to form a stable protective film on the metal surface, thereby Effectively improve the wear resistance and corrosion resistance of lubricating oil.
This article will conduct in-depth discussion on the enhancement effect of 2-IP yamimidazole on the performance of advanced lubricant additives, analyze its performance in different application scenarios, and combine relevant domestic and foreign literature to elaborate on its working principle, experimental data and future in detail Application prospects. I hope that through the introduction of this article, readers will have a more comprehensive understanding of the application of 2-IPMI in the field of lubricating oil, and also provide valuable reference for research and development in related fields.
2-Chemical structure and characteristics of isopropyliimidazole
2-Isopropylimidazole (2-IPMI, referred to as 2-IPMI) is an organic compound and belongs to an imidazole derivative. Its molecular formula is C6H10N2 and its molecular weight is 114.16 g/mol. The chemical structure of 2-IPMI consists of an imidazole ring and an isopropyl side chain. Specifically, the nitrogen atoms on the imidazole ring are connected to isopropyl, forming a unique molecular configuration. This structure gives 2-IPMI a range of excellent physical and chemical properties, giving it a wide range of application potential in the field of lubricating oil additives.
Molecular Structure Analysis
The molecular structure of 2-IPMI can be divided into two parts: imidazole ring and isopropyl side chain. Imidazole ring is a five-membered heterocycle containing two nitrogen atoms, where one nitrogen atom is at the end of the ring and the other nitrogen atom is connected to isopropyl. The presence of imidazole rings makes 2-IPMI have strong polarity and reactive activity, and can chemically adsorb with the metal surface to form a stable protective film. The isopropyl side chain imparts a certain hydrophobicity to 2-IPMI, which contributes to its solubility and dispersion in lubricating oil.
Physical and chemical properties
2-The physical and chemical properties of IPMI are shown in the following table:
| Nature | Value |
|---|---|
| Molecular formula | C6H10N2 |
| Molecular Weight | 114.16 g/mol |
| Melting point | 85-87°C |
| Boiling point | 230-232°C |
| Density | 1.02 g/cm³ |
| Solution | Easy soluble in, etc., slightly soluble in water |
| pH value | 7.0-8.0 |
| Flashpoint | 105°C |
| Refractive index | 1.505 (20°C) |
As can be seen from the above table, 2-IPMI has a high melting point and boiling point, which makes it still stable under high temperature environments. Furthermore, the density of 2-IPMI is close to that of water and has certain hydrophilicity and hydrophobicity, which contributes to its uniform dispersion in the lubricating oil. It is worth mentioning that the pH value of 2-IPMI is close to neutral and will not cause corrosion to the metal surface, which is particularly important for lubricating oil additives.
Chemical Reactivity
2-IPMThe chemical reactivity of I is mainly reflected in the nitrogen atoms on its imidazole ring. The nitrogen atoms on the imidazole ring have a high electron cloud density and are prone to coordinate with metal ions or other polar molecules to form stable complexes. This characteristic allows 2-IPMI to form a dense protective film on the metal surface, effectively preventing oxygen, moisture and other corrosive substances from contacting the metal in the external environment, thereby playing a role in corrosion resistance.
In addition, 2-IPMI can also work synergistically with other additives in the lubricant to further improve the overall performance of the lubricant. For example, when 2-IPMI is used together with antiwear agents, antioxidants, etc., the wear resistance and oxidation resistance of the lubricant can be significantly improved and the service life of the lubricant can be extended.
Application Advantages
2-IPMI's advantages as a lubricant additive are mainly reflected in the following aspects:

In order to verify the enhancement effect of 2-isopropylimidazole (2-IPMI) on lubricating oil performance, the researchers conducted a large number of experimental studies, covering multiple aspects such as wear resistance, corrosion resistance, and oxidation resistance. . The following will introduce the performance of 2-IPMI in different performance tests in detail and analyze it in combination with experimental data.
Anti-wear performance test
Abrasion resistance is one of the important indicators for measuring the performance of lubricating oil. Under high load and high temperature conditions, greater friction will occur between the friction pairs of mechanical equipment, resulting in increased wear. To evaluate the effect of 2-IPMI on the wear resistance of lubricant oil, the researchers used a four-ball test machine to test the wear resistance. The four-ball test machine simulates the actual working conditions and measures the wear of lubricating oil under different loads and speeds.

It can be seen from Table 1 that with the increase of 2-IPMI addition, the diameter of wear spots gradually decreases, indicating that 2-IPMI can significantly improve the wear resistance of lubricating oil. Especially when the amount of 2-IPMI added reaches 1.5%, the diameter of the wear spots is reduced by 25% compared to the base oil without additives, showing a significantAnti-wear effect. This result shows that 2-IPMI can form a stable protective film on the metal surface, effectively reducing direct contact between friction pairs and thus reducing wear.

| 2.0 | 15.6 |
It can be seen from Table 2 that with the increase of 2-IPMI addition, the corrosion area of the metal surface gradually decreases, indicating that 2-IPMI can significantly improve the corrosion resistance of lubricating oil. Especially when the amount of 2-IPMI added reaches 2.0%, the corrosion area is reduced by 55.7% compared with the base oil without additives, showing a significant corrosion resistance. This result shows that the imidazole ring of 2-IPMI can chemically adsorb the metal surface, forming a dense protective layer, effectively preventing oxygen, moisture and other corrosive substances from contacting the metal in the external environment, thereby preventing the metal from being corroded. .

Especially when the amount of 2-IPMI added reaches 2.0%, the acid value is 46.2% lower than that of base oil without additives, showing a significant antioxidant effect. This result shows that 2-IPMI has a certain antioxidant ability, can delay the aging process of lubricant and extend the service life of lubricant. Especially in high temperature environments, 2-IPMI can effectively inhibit the formation of free radicals and prevent the lubricating oil from oxidizing and deteriorating.
Purity and Dispersion Performance Test
