Allyl alcohol or 2-propen-1-ol is an organic compound with the formula CH2=CHCH2OH.
Allyl alcohol is a water soluble, colourless liquid with an ethanol like odour at low concentrations and a mustard-like pungent odour at higher concentration.
Allyl alcohol is used as a pesticide and as a raw material for the production of many chemical compounds.
Allylic alchohol is one in which -OH i.e. hydroxyl group attached to the carbon which is attached to a carbon with a double bond.
Allyl alcohol is a colorless liquid with a pungent, mustard-like odor, soluble in water, and with a chemical structure of CH2CHCH2OH.
Allyl alcohol is synthesized by the hydrolysis of allyl chloride or isomerization of propylene oxide.
Allyl alcohol is used as a raw material in manufacturing of various polymers, pharmaceuticals, pesticides, and other allyl compounds.
USES OF ALLYL ALCOHOL:

APPLICATION OF ALLYL ALCOHOL:
Used to induce a mouse model of liver damage that has been used to study the mechanisms of hepatotoxicity and hepatic stem cell-mediated repair.
Allyl alcohol may be used in the preparation of propylene via photocatalytic transfer hydrogenolysis in the presence of Pd/TiO2 catalysts.
Allyl alcohol was used to grow fitter yeast.
Allyl alcohol is converted mainly to glycidol, which is a chemical intermediate in the synthesis of glycerol, glycidyl ethers, esters, and amines.
Also, a variety of polymerizable esters are prepared from allyl alcohol, e.g. diallyl phthalate.
Allyl alcohol is used as an intermediate compound for synthesizing raw materials such as epichlorohydrin C3H5ClO and 1,4- butanediol C4H10O2, and this development is bringing about expansion of the range of uses of allyl alcohol.
The term allyl of allyl compounds is derived from allium, the Latin word for garlic.

CHEMICAL PROPERTIES OF ALLYL ALCOHOL:
Allyl alcohol is a flammable, colorless liquid.
Allyl alcohol has a pungent, mustard-like odor.
Allyl alcohol is used in making drugs, organic chemicals, pesticides, in the manufacture of allyl esters, and as monomers and prepolymers for the manufacture of resins and plastics.
Allyl alcohol has a large use in the preparation of pharmaceutical products, in organic synthesis, and as a fungicide and herbicide.
Occupational workers engaged in industries such as the manufacture of drugs, pesticides, allyl esters, organic chemicals, resins, war gas, and plasticizers, are often exposed to this alcohol.
PHYSICAL PROPERTIES OF ALLYL ALCOHOL:
Colorless, mobile liquid with a pungent, mustard-like odor at high concentrations.
At low concentrations, odor resembles that of ethyl alcohol.
PRODUCTION OF ALLYL ALCOHOL:
Allyl alcohol can also be made by the rearrangement of propylene oxide, a reaction that is catalyzed by potassium alum at high temperature.
The advantage of this method relative to the allyl chloride route is that it does not generate salt.
Hydrolysis of this acetate gives allyl alcohol.
In alternative fashion, propylene can be oxidized to acrolein, which upon hydrogenation gives the alcohol.
Allyl alcohol can be obtained by many methods: hydrolysis of allyl chloride, by oxidation of propylene oxide with potassium alum at high temperature, dehydrogenation of propanol, and the by reaction of glycerol and formic acid.
Allyl alcohol is the smallest representative of the allylic alcohols.
Allyl alcohols in general can be prepared by allylic oxidation of allyl compounds by for instance selenium dioxide.
Allyl alcohol is prepared by several different processes, the original is alkaline hydrolysis of allyl chloride by steam injection at high temperatures.
A more recent commercial process used oxidation of propylene to acrolein, which in turn reacts with a secondary alcohol to yield allyl alcohol and a ketone.
In this process, allyl alcohol is not isolated, but its aqueous stream is converted directly to glycerol.
The most recent commercial process is isomerization of propylene oxide over a lithium phosphate catalyst.
STORAGE OF ALLYL ALCOHOL:
-Separated from strong oxidants and food and feedstuffs.
