Dehydration of liqors is useful since readily converted to an liqor to an alkene. A simple example is the synthesis of cyclohexene by dehydration of cyclohexanol. You can see the action of acid (H2SO4) sulfuric acid which removes the hydroxyl group of liqor, generating the double bond and water (alcohol assessment). The hydroxyl is replaced by a halogen in Appel reaction. Many liqors may be created by fermenting yeast fruit or grain, but only ethanol is produced commercially this way, mainly as a fuel and as a beverage. Other liqors are generally produced as synthetic derivatives of natural gas or oil.
The acidity of hydroxyl group is similar to that of water, although it depends mainly steric hindrance and the inductive effect. If a hydroxyl is bonded to a tertiary carbon, it is less acidic than if he were bound to a secondary carbon, and in turn it would be less acidic than if I was bound to a primary carbon, because steric hindrance prevents the molecule is effectively solvate. The inductive effect increases the acidity of liqor if the molecule has a large number of electronegative atoms attached to adjacent carbons (electronegative atoms help stabilize the negative charge of oxygen by electrostatic attraction).
The kit liqor can have various compositions. Ethyl liqor can be completely to 96 degrees, with an additive such as benzalkonium chloride or a substance to give an unpleasant taste. It is what is known as denatured ethyl liqor. Are also used as denaturants diethyl phthalate and methanol, which makes some toxic methylated spirits.
Lavoisier was the one who revealed the origin and how to produce liqor through the wine fermentation, showing that under the influence of yeast grape sugar is converted into carbonic acid and liqor. He was also studied by Scheele, Gehle, Thenard, Duma and Boullay Berthelot and in 1854 won it for sintesis.
Alternatively the conversion can be directly carried out using thionyl chloride (SOCl2) chloride. An liqor can also be converted to bromoalkane using hydrobromic acid or phosphorus tribromide (PBr3) or iodoalkane using red phosphorus and iodine to generate "in situ" the phosphorus triiodide. Methanol: There are several methods for oxidizing methanol to formaldehyde and / or formic acid, as Adkins-Peterson reaction.
Phenols, are sometimes referred to as individual liqors in which hydroxyl is bonded to a carbon of a benzene ring. Their reactivity is so different from that of other liqors (here the carbon bearing the OH group is not tetrahedral), phenols are generally classified outside the liqor family.
There is also a group sometimes regarded as a special case of liqors called enols. This is a molecule in which hydroxyl is attached to a carbon of a double bond C equals C (again carbon bearing the -OH group is not tetrahedral). This is actually a tautomeric form of an aldehyde or ketone. The major form is usually the aldehyde or ketone, and not the enol, except in special cases where the enol form is stabilized by mesomerism as phenols.
Dehydration of liqors is a chemical process consisting of transformation of an liqor to be an alkene by removal processes. To perform this procedure a mineral acid is used to extract the hydroxyl group (OH) from the liqor, generating a positive charge on the carbon which was extracted hydroxyl which has an electrical interaction with nearby electrons (by default, electrons a hydrogen in case of not having another substituent) to form a double bond in place.
