For simple mono-alcohols, which is the focus on this article, the following are most important industrial alcohols: The combined capacity of the other alcohols is about the same, distributed alcoholes secundarios equally.

Alcoholes secundarios of several milliliters are tolerated. Methanol and ethanol are less acutely toxic. All alcohols are mild skin irritants.

In this way methanol will be excreted intact in urine.

Those groups can form hydrogen bonds to one another and to most other compounds. Owing to the presence of the polar OH alcohols are more water-soluble than alcoholes secundarios hydrocarbons.

Methanol, ethanol, and propanol are miscible in water. Butanolalcoholes secundarios a four-carbon chain, is moderately soluble.

Because of hydrogen bondingalcohols tend to have higher boiling points than comparable hydrocarbons and ethers.

The boiling point of the alcohol ethanol is Occurrence in nature Alcoholes secundarios alcohols are found widely in nature. Ethanol is most alcoholes secundarios because it is the product of fermentation, a major energy-producing pathway.

The other simple alcohols are formed in only trace amounts. More complex alcohols are pervasive, as manifested in sugars, some amino acids, and fatty acids.

Production Ziegler and oxo processes In the Ziegler processlinear alcohols are produced from ethylene and triethylaluminium followed by oxidation and hydrolysis. Many higher alcohols are produced by alcoholes secundarios of alkenes followed by hydrogenation. When applied to a terminal alkene, as is common, one typically obtains a linear alcohol: Hydration reactions Some low molecular weight alcohols alcoholes secundarios industrial importance are produced by the addition of water to alkenes.

Ethanol, isopropanol, 2-butanol, and tert-butanol are produced by this general method. Two implementations are alcoholes secundarios, the direct and indirect methods. The direct method avoids the formation of stable intermediates, typically using acid catalysts.

In the indirect method, the alkene is converted to the sulfate esteralcoholes secundarios is subsequently hydrolyzed.

The direct hydration using ethylene ethylene hydration [26] or other alkenes from cracking of fractions of distilled crude oil. Hydration is also used industrially to produce the diol ethylene glycol from ethylene oxide.

For instance, such a process might proceed by the conversion of sucrose by the enzyme invertase into glucose and fructosethen the conversion of glucose by the enzyme complex zymase into alcoholes secundarios and carbon dioxide.

Several species of the benign bacteria in the intestine use fermentation as a form of alcoholes secundarios metabolism. This metabolic reaction produces ethanol as a waste product. Thus, human bodies contain some quantity of alcohol endogenously produced by these bacteria.

In rare cases, this can be sufficient to cause " auto-brewery syndrome " alcoholes secundarios which intoxicating quantities of alcohol are produced. The bacterium Clostridium acetobutylicum alcoholes secundarios feed on cellulose to produce butanol on an industrial scale.

Secondary and especially tertiary alkyl halides will give the elimination alkene product instead.
