1 -Chlorooctadecane

Chemicals and Standard Solutions. Cyclohexanone, cyclohexanol, 1,3,5-trichlorobenzene, 1,2,4-trichlorobenzene, phenol, 4-methylphenol, 4-chloro-phenol, 1,2,3,4-tetrahydroisoquinoline, 1-chlorohexane, 1-chlorododecane, and 1-chlorooctadecane were obtained from Aldrich. Acetone, tetrahydrofuran, ethyl acetate, toluene, dimethyl sulfoxide, and methanol were obtained from J. T. Baker. Distilled-in-glass isooctane, methylene chloride, ethyl ether, and pentane were obtained from Burdick and Jackson. Analytical standard kits from Analabs provided methyl ethyl ketone, isopropyl alcohol, ethanol, methyl isobutyl ketone, tetrachloroethylene, dodecane, dimethylformamide, 1,2-dichlorobenzene, 1-octanol, nitrobenzene, 2,4-dichlorophenol, and 2,5-dichlorophenol. All chemicals obtained from the vendors were of the highest purity available and were used without further purification. High-purity water... 

Gas chromatographic-mass spectrometric (GC-MS) calibration standard mixes for quantitation were prepared in ethyl ether at concentrations of 20, 50, and 75 ppm. Internal standard spiking solution containing 1-chlorohexane, 1-chlorododecane, and 1-chlorooctadecane was prepared from individual stock solutions in methanol of each component. Two hundred microliters of each solution were added to ethyl ether and diluted to 2 mL. Forty microliters of this internal standard mix was added to the column extracts before diluting to 2 mL to yield a final concentration of 100 ppm per internal standard component. 

A13-28591 1-Chlorooctadecane EINECS 222-207-7 NSC 5543 Octadecane, 1-chloro- Octadecyl chloride n-Octadecyl chloride. Solid mp = 28.6° bp = 348° d = 0.8641 insoluble in H2O, slightly soluble in CCI4. 

Mechanism 5.4 shows the E2 mechanism for the reaction of 1-chlorooctadecane with potassium ferf-butoxide presented in the preceding section. The bimolecular transition state is characterized by partial bonds between f rf-butoxide and one of the hydrogens at C-2 of 2-chlorooctadecane, a partial double bond between C-1 and C-2, and a partial bond between C-1 and chlorine.
