4-Nonylphenol
4-Nonylphenol (CAS: 104-40-5) is an alkylphenol with a nine-carbon chain para to the hydroxyl group. It is used as an intermediate for nonionic surfactants and resin modifiers.
It is practically insoluble in water and soluble in most organic solvents.
Because nonylphenol is regulated in some regions, buyers should check local restrictions before use.
It should be stored closed, away from oxidisers and heat. Typical specifications include assay by GC, colour, water and isomer content. Regulatory limits apply in some regions, so users should check compliance.
• Surfactant production: ethoxylation gives nonionic surfactants for industrial uses. Ethoxylation degree sets the HLB and end use.
• Resin and antioxidant intermediate: used in phenolic resins and phosphite stabilisers. Alkylphenol-based additives are used in some industrial products.
• Lubricant and fuel additives: raw material for detergent and dispersant additives. Use may be restricted in some applications, so alternatives are often considered.
• Industrial intermediates: used in the manufacture of nonylphenol phosphite stabilisers and other polymer additives.
