The chemical ionization mass spectra of some tert ‐octylphenol ethoxylates and linear alcohol ethoxylates have been determined using methane and ammonia as reactant gases. Proton, [C 2 H 5 ] + and [C 3 H 5 ] + adducts were observed with attachment on the ring as well as on the oxyethylene chain for the tertiary octylphenol ethoxylates. Proton and [NH 4 ] + addition reactions were also observed. Alkyl ion and olefin displacement reactions were also important fragmentations. Hydride abstraction and proton, [C 2 H 5 ] + , [C 3 H 5 ] + and [NH 4 ] + attachment were the most important reactions occurring for the linear alcohol ethoxylates.
