Antioxidants play a crucial role in various industries, especially in polymer and plastic production, to prevent the degradation of materials caused by oxidation. Antioxidant 1098 is one such significant antioxidant that has gained wide - spread use. In this blog, as a supplier of Antioxidant 1098, I'll discuss its CAS number, properties, applications, and how it compares with other antioxidants.
What is the CAS Number of Antioxidant 1098?
The Chemical Abstracts Service (CAS) number is a unique numerical identifier assigned to every chemical substance described in the open scientific literature. For Antioxidant 1098, its CAS number is 23128 - 74 - 7. This number serves as a global standard for identifying this specific antioxidant, making it easier for researchers, manufacturers, and suppliers to refer to it accurately in scientific papers, product specifications, and regulatory documents.
Chemical Structure and Properties of Antioxidant 1098
Antioxidant 1098 is a hindered phenolic antioxidant. Its chemical name is N,N'-Hexane - 1,6 - diylbis[3 - (3,5 - di - tert - butyl - 4 - hydroxyphenyl)propionamide]. The presence of the hindered phenolic group is the key to its antioxidant activity. The bulky tert - butyl groups on the phenolic ring sterically hinder the approach of free radicals, allowing the phenolic hydrogen to be readily donated to free radicals, thus terminating the radical chain reaction of oxidation.
It is a white to off - white powder with good solubility in organic solvents such as benzene, chloroform, and acetone, but has low solubility in water. This property makes it suitable for use in non - aqueous polymer systems. Antioxidant 1098 also has excellent thermal stability, which means it can maintain its antioxidant effectiveness even at relatively high processing temperatures.
Applications of Antioxidant 1098
- Polyamide (PA) Industry: Polyamides are widely used in engineering plastics, fibers, and films. However, they are prone to oxidation during processing and long - term use. Antioxidant 1098 can effectively protect polyamides from thermal and oxidative degradation, improving their mechanical properties, color stability, and service life. For example, in the production of PA6 and PA66 fibers used in carpets and textiles, adding Antioxidant 1098 can prevent the fibers from yellowing and becoming brittle over time.
- Polyolefin (PO) Industry: Although polyolefins like polyethylene (PE) and polypropylene (PP) have good chemical resistance, they are also susceptible to oxidation. Antioxidant 1098 can be used in combination with other additives to enhance the antioxidant performance of polyolefins. It helps to maintain the physical and mechanical properties of polyolefin products, such as pipes, automotive parts, and packaging materials, under different environmental conditions.
- Elastomer Industry: Elastomers such as styrene - butadiene rubber (SBR) and ethylene - propylene - diene monomer (EPDM) are often exposed to oxygen, heat, and mechanical stress. Antioxidant 1098 can protect these elastomers from oxidative aging, improving their flexibility, resilience, and resistance to cracking.
Comparison with Other Antioxidants
- Antioxidant K300: Antioxidant K300 is another type of antioxidant. While Antioxidant 1098 is mainly a hindered phenolic antioxidant, Antioxidant K300 may have a different chemical structure and mechanism of action. Antioxidant K300 might be more suitable for certain specific polymer systems or applications where its unique properties can be fully utilized. For example, if a polymer requires an antioxidant with high solubility in a particular solvent or has a specific processing temperature range, Antioxidant K300 could be a better choice. However, Antioxidant 1098's excellent thermal stability and effectiveness in polyamide and polyolefin systems give it an edge in many common applications.
- Antioxidant 1010: Antioxidant 1010 is also a well - known hindered phenolic antioxidant. Compared to Antioxidant 1098, Antioxidant 1010 has a more complex molecular structure with multiple hindered phenolic groups. This gives Antioxidant 1010 a higher antioxidant efficiency in some cases, especially in polyolefin systems. However, Antioxidant 1098 has better compatibility with polyamides due to its specific chemical structure, making it a preferred choice for polyamide - based products.
- Antioxidant B215: Antioxidant B215 is a blend of a primary antioxidant (usually a hindered phenolic antioxidant) and a secondary antioxidant (such as a phosphite antioxidant). The combination of two types of antioxidants in Antioxidant B215 provides a synergistic effect, which can effectively prevent both the initial oxidation and the subsequent degradation of polymers. In contrast, Antioxidant 1098 is a single - component antioxidant. Depending on the specific requirements of the polymer system, either a single - component antioxidant like Antioxidant 1098 or a blended antioxidant like Antioxidant B215 can be selected.
