Formation and Usage of Salts

The salts of the inorganic esters of nonylphenol with phosphoric acid and sulphuric acid are frequently employed in a variety of applications. For example, the dilithio salt of nonylphenylphosphate has been employed as a component of lubricating greases (ref.42). [Pg.373]

The tungsten salt resulting from treatment of nonylphenol with tungstic hexachloride has found an application as a catayst for the metathetical copolymerisation of dicyclopentadiene and 5,5,6-trlchloronorbornene (ref. 43). Antimony and lead salts of alkyidithiophosphates are important additives for lubricating greases. In the nonylphenyl series such compounds are considered to have the dimeric structure shown (where M = Pb and Sb) (ref. 44). [Pg.373]

By contrast, the copper salt [M = Cu(ll)] of the monomeric phosphorodithioate has been employed with 4-t-octyldiphenylamine as an antioxidant system and thermal stabiliser for lubricants and hydraulic fluids (ref.45). [Pg.373]

The barium salt of nonylphenol has found use as a additive component of mixtures employed as detergents for lubricating oils (ref.46). [Pg.373]

Whereas the 1,1,3,3-tetramethylbutyl side chain structure in t-octylphenol derived from diisobutene is usually the sole contributor, that in t-nonylphenol comprises a complex but nevetheless extremely useful mixture. Recent work on the separation of the isomers present on a cross-linked methylsilcone column by capillary GLC (ref. 47) could be useful in indicating the connection between structure and the properties in this valuable technical product. [Pg.373]
