3- Methyl-3-hexanol

Other studies of the preferential solvation for which information can be derived from KBIs in ternary systems have also been made. The system -heptane -i- ethanol + 1-propanol at 313 K (Zielkiewicz 1995a) showed that ethanol and 1-propanol mix in a random manner in the presence of -heptane with no preferential solvation between these two solvents. The same author studied the solvation of N,N-dimethylformamide (C) in mixtures of water (A) and each of methanol, ethanol, and 1-propanol (B) at 313 K (Zielkiewicz 1995b). At Xc > 0.8 this component was solvated equally by A and B, but at Xc < 0.15 it was preferentially hydrated, that is, solvated by A, except when x > 0.8, where the solvation of C by A and B was random. A,A-dimethylformamide (C) featured also in the studies (Ruckenstein and Shulgin 2001a) of it in aqueous (A) methanol (B). The KBIs in the system n-hexane + 1-hexanol + methyl benzoate were studied at 298 K (Aparicio et al. 2005). They calculated the excess (or deficit) number of molecules of, say. A, around molecules of B in pseudobinary systems at constant mole fraction of C from...

Use the apparatus detailed in Section 111,20. Dissolve 100 g. (123 ml.) of methyl n-butyl ketone (2-hexanone) (Section 111,152) in 750 ml. of ether and add 150 ml. of water. Introduce 69 g. of clean sodium in the form of wire (or small pieces) as rapidly as possible the reaction must be kept under control and, if necessary, the flask must be cooled in ice or in running water. When all the sodium has reacted, separate the ethereal layer, wash it with 25 ml. of dilute hydrochloric acid (1 1), then with water, dry with anhydrous potassium carbonate or with anhydrous calcium sulphate, and distil through a fractionating column. Collect the fraction of b.p. 136-138°. The yield of methyl n-butyl carbinol (2-hexanol) is 97 g.

Plasticizer Range Alcohols. Commercial products from the family of 6—11 carbon alcohols that make up the plasticizer range are available both as commercially pure single carbon chain materials and as complex isomeric mixtures. Commercial descriptions of plasticizer range alcohols are rather confusing, but in general a commercially pure material is called "-anol," and the mixtures are called "-yl alcohol" or "iso...yl alcohol." For example, 2-ethyIhexanol [104-76-7] and 4-methyl-2-pentanol [108-11-2] are single materials whereas isooctyl alcohol [68526-83-0] is a complex mixture of branched hexanols and heptanols. Another commercial product contains linear alcohols of mixed 6-, 8-, and 10-carbon chains.

What about the configuration at C2, the newly formed chirality center As illustrated in Figure 9.16, the stereochemistry at C2 is established by reaction of H20 with a carbocation intermediate in the usual manner. But this carbocation does not have a plane of symmetry it is chiral because of the chirality center at C4. Because the carbocation has no plane of symmetry, it does not react equally well from top and bottom faces. One of the two faces is likely, for steric reasons, to be a bit more accessible than the other face, leading to a mixture of R and 5 products in some ratio other than 50 50. Thus, two diastereomeric products, (2/L4 K)-4-methyl-2-hexanol and (25,4/ )-4-methyl-2-hexanol, are formed in unequal amounts, and the mixture is optically active.
