Dodecyl nitrile

Consider the properties of reactive surface-active (RS) substances (alkyl phenol oxyethylated ester (OP-10), dodecyl nitrile (DDN)) and of chemically indifferent smface-active substances (IS) like the ohgo-amidoamines L-18, L-19, L-20 capable of reacting with such oligomeric solvents as the ED-20 and DEG-1 epoxy resins and polyoxypropylene-triol (POPT) of molecular weight 750. These oligomers are imasso-ciated low-polarity liquids, as confirmed by the data of Table 2.1. 

The 1,3-dipolar cycloadditions of benzonitrile oxides with tertiary cinnamides yield the 5-phenyl and 4-phenyl regioisomers in a reversal of the expected regioselectiv-ities shown with methyl cinnamate. Calculations have shown that steric factors are responsible for this reversal of regioselectivity." The 1,3-dipolar cycloadditions of benzonitrile oxide with electron-rich and electron-poor dipolarophiles are accelerated by sodium dodecyl sulfate micelles. Phenyl nitrile ylides react with electron-deficient alkenes to produce five-membered -heterocycles where measured rate constants are between 4 x 10 and 7 x 10 lmoP ...

Analytical and Tast Methods. Numerous instrumental and chemical techniques are available for the determination of acrylonitrile. The method of choice is directed by the concentration and the medium involved. For direct assay of acrylonitrile, titrimetric procedures are frequently used. Dodecyl mercaptan reacts with acrylonitrile under base catalysis excess mercaptan is then hacktitrated with an acid bromate-iodide solution (63), or alternatively, for colored solutions, with silver nitrate (64). Hydrolysis of the nitrile with strong base generates ammonia, which can then be determined by Nessler s reagent (65).
