P-dodecylphenol

Mainly POE p-nony I phenol, p-octylphenol, or p-dodecylphenol (sometimes, dinon-ylphenol), derived from disobutylene, propylene trimer, or propylene tetramer. 

Preparation by reaction of benzenyl trichloride (benzo-trichloride) with p-dodecylphenol in carbon disulfide inthe presence of aluminium chloride, first between -20° and -15°, then at 0-5° for 1 h (38%) [889-891]. 

About 45% of phenol is used as a feedstock to produce bisphenol A. Another 30% is used to produce phenolic resins. An additional 10% is used to make caprolactam. About 2% is used to produce aniline. Phenol is used as a feedstock to produce alkyl-phenols such as /hnonylphenol and p-dodecylphenol. In addition, it is used to make xylenols as well as adipic acid and salicylic acid. Phenol is used in the synthesis of various dyes and biocides. 

The influence of sodium dodec3d sulfate, hexadecyltrimethyl-ammonium bromide and a polyoxyethylene(18) dodecylphenol on the hydrolysis of the Schiff bases p-chlorobenzylidene-l,l-dimethylethyl-amine, p-methoxybenzylidene-l,l-dimethylethylamme, and benz-hydrilidenedimethylammonium iodide (iV,iV-dimethylbenzophenone-imonium iodide) have been investigated (Behme and Cordes, 1965). The observed pseudo-first order rate constant for the hydrolysis ofp-chloro-...

Alkylation of phenol with dodecene (propylene tetramer) produces 4-dodecylphenol. It is most commonly used in the manufacture of compounds for a wide variety of lube-oil additives but also of specialty surfactants and demulsifiers. It is available in liquid form and generally sold in 55 gallon drums, bulk shipments of 5000 gallon tank wagons, or up to 25,0(X) gallon railcars [1, p. 133 2] (Structure 3.5).
