FD-MS is also an effective analytical method for direct analysis of many rubber and plastic additives. Lattimer and Welch [113,114] showed that FD-MS gives excellent molecular ion spectra for a variety of polymer additives, including rubber accelerators (dithiocar-bamates, guanidines, benzothiazyl, and thiuram derivatives), antioxidants (hindered phenols, aromatic amines), p-phcnylenediamine-based antiozonants, processing oils and phthalate plasticisers. Alkylphenol ethoxylate surfactants have been characterised by FD-MS [115]. Jack-son et al. [116] analysed some plastic additives (hindered phenol AOs and benzotriazole UVA) by FD-MS. Reaction products of a p-phenylenediaminc antiozonant and d.v-9-lricoscnc (a model olefin) were assessed by FD-MS [117],...

Alkylphenol. Alkylphenol is a common surfactant intermediate used to produce alkylphenol ethoxylates. Phenol reacts with an olefin thermally without a catalyst but with relatively poor yields. Catalysts for the reaction include sulfuric acid p-toluene sulfonic acid (PTSA), strong acid resins, and boron trifluoride (BF3). Of these, strong acid resins and BF3 are mostly widely used for the production of surfactant-grade alkylphenols. The most common alkylphenols are octylphenol, nonylphenol, and dodecylphe-nol. Mono nonylphenol (MNP) is by far the most common hydrophobe. It is produced by the alkylation of phenol with nonene under acid conditions. All commercially produced MNP is made with nonene based on propylene trimer. Because of the skeletal rearrangements that occur during propylene oligomerization, MNP is a complex mixture of branched isomers.

Higher n-olefins of Cs-Ci4 are used as intermediates in the manufacture of several types of surfactant materials. Linear internal olefins are used in the production of linear alkylbenzene alkylphenol detergent alcohols, which in turn is used to produce alcohol sulfates, alcohol ethoxylates, and alcohol ether sulfates and synthetic lubricants. a-Olefins are used in the production of detergent alcohols, linear alkylbenzene, synthetic lubricants, and a-olefin sulfonates (another ionic surfactant). 

Alkylphenol p-dodecyl phenol is the product of a mixture of branched-chain, 12-carbon-containing olefins, and phenol yielding the general structure as shown in Structure 3.14. Although the major use of PDDP is in lube-oil additives (primarily through its conversion to a calcium phenolate), a minor, higher purity portion is ethoxylated to produce specialty surfactants.
