To 1,320 parts of methyl isobutyl ketone is added 570 parts of 3-diethylamino-1 -cyclohexyl-1 -phenylpropanol-1 (2 mols) and the mixture is stirred until solution is complete. Then 500 parts (3.2 mols or 60% excess) of ethyl iodide are added. After filtration, the filtrate is diluted with an additional 300 parts of methyl isobutyl ketone and the solution is then heated at the reflux temperature (108°C to 110°C) for 9 hours. After cooling to 0°C, the precipitated solid material is removed by filtration, washed with isopropyl acetate and dried. Approximately 111 parts of product is obtained or a yield of 88.6% based on as-is starting material or 92.5% based on real starting material. 

Similarly to quantitative determination of high surfactant concentrations, many alternative methods have been proposed for the quantitative determination of low surfactant concentrations. Tsuji et al. [270] developed a potentio-metric method for the microdetermination of anionic surfactants that was applied to the analysis of 5-100 ppm of sodium dodecyl sulfate and 1-10 ppm of sodium dodecyl ether (2.9 EO) sulfate. This method is based on the inhibitory effect of anionic surfactants on the enzyme system cholinesterase-butyryl-thiocholine iodide. A constant current is applied across two platinum plate electrodes immersed in a solution containing butyrylthiocholine and surfactant. Since cholinesterase produces enzymatic hydrolysis of the substrate, the decrease in the initial velocity of the hydrolysis caused by the surfactant corresponds to its concentration. Amounts up to 60 pg of alcohol sulfate can be spectrometrically determined with acridine orange by extraction of the ion pair with a mixture 3 1 (v/v) of benzene/methyl isobutyl ketone [271].

Alkylation (R" = alkyl or substituted alkyl) is most satisfactorily accomplished with active halogen compounds such as allyl, benzyl, and propargyl halides, but a-halo ketones, esters, and nitriles can also be used.467,474 Treating l-(l-cyclohexenyl)pyrrolidine with allyl bromide in the presence of /V-ethyl-dicyclohexylamine as base leads to introduction of two allyl groups, i.e., formation of 2,6-diallylcyclohexanone.475 Arylation can be effected by, for example, l-chloro-2,4-dinitrobenzene (R" = 2,4-dinitrophenyl).476 A-Isobutyl-fl-butylamine477 and pyrrolidine478 have been recommended as amine components for C-alkylation by simple alkyl halides such as ethyl and methyl iodides.
