Alkylphenols

In 1997, Dover Chemical built a state-of-the-art manufacturing facility to produce alkylphenol products. After several expansions and updates, today's facility is totally automated, assuring our customers of consistent quality para- and di-nonylphenol and para- and di-cumylphenol. This plant represents a major investment in Dover Chemical's strategy to become a global supplier to the polymer industry.

SURFACTANTS

The largest industrial use for alkylphenol is in the manufacture of nonionic surfactants. These ethoxylated alkylphenol surfactants have good chemical stability and excellent wetting, emulsifying and detergent properties.

TNPP

Nonylphenol is reacted with phosphorus trichloride to produce trisnonylphenyl phosphite (TNPP), a common antioxidant for a wide range of polymer systems.

PHENOLIC RESINS

Nonylphenol reacts with aldehydes to yield phenolic resins. When used with other phenols, even in small quantities, it makes the phenolic resins more water resistant, more soluble in oil, and improves electrical properties.

 

RUBBER CHEMISTRY

Nonylphenol sulfide has been used as a reclaiming agent for synthetic rubber.

PVC

A variety of alkylphenol derivatives have uses as polyvinyl chloride plasticizer intermediates. These intermediates include nonylphenol benzoate, nonylphenol alkanesulfonates and nonylcyclohexanol.

EPOXY RESINS

Nonylphenol can be used in an epoxy resin hardener.

MISCELLANEOUS

Other applications for alkylphenols include pharmaceuticals, corrosion inhibitors, dyestuffs, ore flotation agents, insecticides, bactericides, chemical stabilizers, and the leather industry. Overbased calcium salt of nonylphenol can be used as a dispersant in hydraulic fluid and motor oil.
