Ethyl hexanol, sometimes called 2-ethyl hexyl alcohol, 2-ethyl hex, or more simply 2-EH, is one of the oldest high molecular weight aliphatic alcohols. What does it have in common with NBA Both are made from propylene via the Oxo process, and both have the same aldehyde intermediate— normal butyraldehyde. 

Acetaldehyde is made by the direct oxidation of ethylene, C2H4. It is a liquid at room temperature and is an intermediate in the production of acetic acid, acetic anhydride, butyl, and 2-ethyl hexyl alcohol.

Ethyl hexyl Alcohol n (2-ethylhexanol, octyl alcohol) C4H9CH(C2—H5)CH20H. An involatile solvent with many uses in the plastics industry. As a solvent, it is used in coatings for stenciling, silk screening, and dipping. As an intermediate, the alcohol is an important raw material for the production of the 2-ethylhexyl esters of dibasic acids used as plasticizers, such as dioctyl phthalate, adipate, and azelate. 

M-Hexyl alcohol has been prepared by the reduction of ethyl caproate by means of sodium and absolute alcohoB alone or in anhydrous ammonia solution by the reduction of -caproamide by means of sodium and absolute alcohol by the reduction of -caproaldehyde by means of sodium amalgam in dilute sulfuric acid and by means of living yeast, It has also been produced by the action of nitrous acid upon w-hexylamine by the action of sodium upon a mixture of ethyl alcohol and M-butyl alcohol ...

Chemical/Physical. Hydrolyzes in water to o-phthalic acid (via the intermediate 2-ethyl-hexyl hydrogen phthalate) and 2-ethylhexyl alcohol (Kollig, 1993 Wolfe et al., 1980). Although no pH value was given, the reported hydrolysis rate constant under alkaline conditions is 1,400/M-yr (Ellington et al., 1993 Kollig, 1993). A second-order rate constant of 1.1 x 10 /M-sec was reported for the hydrolysis bis(2-ethylhexyl) phthalate at 30 °C and pH 8 (Wolfe et al., 1980).

It is observed that at room-temperature (300°K), the bonded OH frequency for methyl, ethyl, isopropyl, -butyl, isoamyl and n-hexyl alcohols decreases 30, 35, 44, 49, 44, and 50 cm" 1 respectively. 

Plasticizer. The polymer tubing extractor contains the plasticizer l,2-bis(ethylhexyl) phthalate. Longer exposures to 0.1 M NaOH indicated that electroactive hydrolysis products of plasticizer, probably ethyl and hexyl alcohols, were produced, as suggested by the following peak currents given in nanoamperes (the times of the peak currents are given in parentheses) 30 (2 min), 7 (1 min), 5 (30 s), and 2 (15 s). The analytical procedure presented here uses back extraction times of less... 

Jennings et al (228) fractionated an extract from Bartlett pears into 32 volatile components of which five were found to contribute significantly to the characteristic pear aroma. Later studies indicated that esters of trans-2 cis-4 decadienoic acid and hexyl acetate were significant components of the Bartlett pear aroma (229, 230). More recently, numerous volatiles of Bartlett pears were separated and identified including esters of methyl, ethyl, propyl, butyl, and hexyl alcohols, and Cio to Ci8 fatty acids (231, 232).

In addition to these two studies the polymerization kinetics of three different Nd-compounds which were activated by DIBAH and EASC were comparatively studied. In this investigation a Nd alcoholate [NdA = neodymium(III) neopentanolate], a Nd phosphate [NdP = neodymium(III) 2-ethyl-hexyl-phosphate] and a Nd carboxylate (NdV) were compared with a special focus on the variation of the molar ratios of zzdibah/hncI and ci/ Nd [272]. For each of these ternary catalyst systems the polymerization activities depend... 

Alcohols and aldehydes are also suitable materials for the creation of an alkyl amine. In addition to the aforementioned formation of alkyl chloride as an intermediate, alcohols can be directly converted to amines under hydrogenation conditions in the presence of ammonia while aldehydes are prereacted to form imine followed by hydrogenation [13]. Selectivity of the primary amine with these techniques is difficult and this process is more typically utilized for the preparation of tertiary amines where the reaction can be driven to completion. In certain cases, alcohols and aldehydes provide structural elements which are not attainable from natural sources. An example is the formation of a hydrogenated tallow 2-ethyl hexyl amine. The amine is prepared as shown below in eqn 6.1.8 using a hydrogenated tallow amine reacted with 2-ethyl hexanal [14, 15] ...

Then the solid V4O9 (20 g) was suspended in 100 g of various fresh alcohols (isopropyl alcohol, isobutyl alcohol, 2- butyl alcohol, 2- methyl-1- butyl alcohol, cyclohexyl alcohol or 2-ethyl-1-hexyl alcohol). The suspension was heated until 383K. (In the cases of isopropyl alcohol and 2- butyl alcohol, the suspension was heated until reflux.) Then, here added an ortho-H3PO4 (18.2 g) in the same alcohol (7.2 g) dropwisely for 30 minutes. The ratio of P to V was 1.13 for preparation of the precursor. After H3PO4 addition, this condition was kept for 5 hours (in the case of isopropyl alcohol, for 24 hours). Then the obtained slurry was filtered. Thus obtained solid was washed with acetone and was dried at 313 K for 15 hours.
