Decane from decanol

Binding parameters and X-ray diffraction patterns of the complex of starch with 1-decanal do not differ significantly from corresponding analyses performed using 1-decanol.656,679 The temperatures of formation of the aldehyde complexes are likewise close to those for relevant starch-alcohol complexes.673,680 Analysis of the binding sites of the complex suggests that both amylose and amylopectin are involved in complexation, but these complexes are rather weak.717... 

The model tests were carried out both iso-thermally (i.e. at constant temperature) and in temperature gradients (from warm to cold). Alcohols (e.g. ethanol, hexanol, octa-nol, decanol), aldehydes (e.g. decanal), ketones (e.g. diacetyl), acids (e.g. caproic acid), esters (e.g. ethyl acetate), terpenes (e.g. menthol, menthone, 6-pinene, limonene), amines (e.g. butyl amine), pyrazines and other classes of substances have been investigated as flavouring substances [6,9,11,13-18]. Fig. 5.6 shows the forma-... 

Another polar solvent that has been used in SDS-stabilized microemulsions is glycerol. Hexanol or decanol have been used as cosurfactants and systems both with and without oil have been studied. The ternary system with hexanol as cosurfactant was examined with SANS and NMR self-diffusion measurements by two different groups and both found the microemulsions to be structureless solutions [130,131], Similar behavior was found from a self-diffusion study of the quaternary systems with p-xylcnc or decane as the oil component [131,132],... 

Heteroatoms in a molecular ion tend to promote fragmentation. Cleavage of the carbon-heteroatom bond and of the bond a to the heteroatom is common. n-Decanol, for example, has a relative molecular ion intensity nearly 1,000 times less than that of n-decane, and the expulsion of HCN from pyridine (Figure 2.58b) is considerably more facile than loss of C2H2 from benzene (Figure 2.58a), depicted by Equation 2.91. 

A number of selective oxidizing agents, such as pyridinium chlorochro-mate, are frequently used for this purpose. With this reagent, the oxidation stops at the aldehyde stage, because the oxidation, as pointed out earlier, is conducted in a nonaqueous solution. Thus, decanal can be obtained from 1-decanol using this reagent (methylene chloride solvent) in 92% yield. Pyridinium chlorochromate (PCQ is a solid, yellow salt prepared from chromium trioxide as shown here ... 

More recently extensive work has been carried out in our group in order to establish some correlations between the rate of water uptake by W/0 microemulsions and the dynamic properties (fluidity or rigidity) of the amphiphilic film. Different additives known to modify the film dynamics (see Sections VI.C and VI.D) were introduced in different proportions in the AOT/n-decane/water system alcohols with different chain lengths (from 1-butanol to 1-decanol), salt (up to 0.3 M), and hydrophilic pol5miers (PEG 2000 and 10,000). A versatile stopped-flow apparatus (Biologic SFM-3) was used, which provided an excellent dispersion of the solutions by their passage through two successive mixers, and which...
