Assessing on the whole the method of the production of alkyl- and aryl-chlorosilanes based on the interaction of alkyl- and arylchlorides with free silicon (i.e. direct synthesis), we should say that this method in comparison with metalorganic synthesis is more efficient, especially for the production of methyl- and phenylchlorosilanes. As for unsaturated chlorosi-lanes (vinyl- and allylchlorosilanes) and organochlorosilanes with higher radicals (hexyl-, heptyl-, octyl- and nonylchlorosilanes), no direct synthesis technique has yet been developed.

Several neutral alkylglucoside surfactants, such as heptyl-, octyl-, nonyl-, and decyl-j8-D-glucopyrano-sides and octylmaltopyranoside, were also employed for the enantiomer separation of phenoxy acid herbicides, Dns-DL-AAs, l,r-bi-2-naphthyl-2,2 -diyl hydrogen phosphate (BNP), warfarin, bupivacaine, and so forth. 

C at 0.3 mm. Tetralkoxyzirconium compounds and trialkoxy-zirconium species have been prepared also by double decomposition of tetrakisacetylacetonatozLTConium and trisacetylacetonatozirconium with alcohols (81). The tetraalkoxy compounds of hexyl, heptyl, octyl, and nonyl alcohols were prepared in this manner with the reaction being complete in 2 to 3 hours. 

Because of their interest in products with liquid crystalline and surfactant properties, Csiba et al. [15] synthesized some amphiphilic derivatives of L-galactono-1,4-lactone 24, a by-product of the sugar beet industry available in large quantities. Reactions between 24 and hexyl, heptyl, octyl, decyl, dodecyl, and myristyl aldehydes on montmorillonite KSF or KIO were performed in a focused open-vessel micro-wave system for 10 min in the absence of solvent (Scheme 12.10). Protected derivatives 25a-f were afforded with yields (60-89%) considerably better than those (22-38%) obtained by conventional heating for 24 h in the presence of sulfuric acid. 

J mol" for hindered rotation about C(a)—C fS), calculated from temperature dependences of H( S) and anisotropy of H(a). n-butyl, -pentyl, -hexyl, -heptyl, -octyl, -nonyl, -decyl, -dodecyl, and -hexadecyl studied in the same manner.

Gorbunova et al. [120,121] grew silver whiskers firom fairly concentrated silver nitrate solutions (>0.30 M) containing oleic acid, gelatin, albumin, heptyl, octyl, and nonyl alcohols. 

The retention behavior of phosphatidic acid methyl esters (C15-C20) was studied on a C18 column (I = 208 nm) using a 70/22/8 acetonitrile/methanol/water (5 mM tetraalkyltriethylammonium phosphate) mobile phase [1184], A number of quaternary alkyltriethylammonium phosphates (pentyl, hexyl, heptyl, octyl, and dodecyl) were tested as the mobile phase modifier. The pentyl gave the best separation. Capacity factors were tabulated for all analytes in all mobile phases. Peaks were not well resolved, indicating that a gradient might have given better results.
