'''Allyl alcohol''' ([[IUPAC name]]: '''prop-2-en-1-ol''') is an [[organic compound]] with the [[structural formula]] {{chem2|CH2\dCHCH2OH}}. Like many [[Alcohol (chemistry)|alcohol]]s, it is a water-soluble, colourless liquid. It is more toxic than typical small alcohols. Allyl alcohol is used as a [[Precursor (chemistry)|precursor]] to many specialized compounds such as flame-resistant materials, [[drying oils]], and [[plasticizers]].<ref name=Ullmann>{{Ullmann|author=Ludger Krähling|author2=Jürgen Krey|author3=Gerald Jakobson|author4=Johann Grolig|author5=Leopold Miksche|title=Allyl Compounds|year=2002|doi=10.1002/14356007.a01_425}}</ref> Allyl alcohol is the smallest representative of the [[allyl]]ic [[Alcohol (chemistry)|alcohol]]s.

==Production==

Allyl alcohol is produced commercially by the [[Olin Corporation|Olin]] and [[Royal Dutch Shell|Shell]] [[corporation]]s through the hydrolysis of [[allyl chloride]]:

:{{chem2|CH2\dCHCH2Cl + NaOH -> CH2\dCHCH2OH + NaCl}}

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. Also avoiding chloride-containing intermediates is the "acetoxylation" of [[propylene]] to [[allyl acetate]]:

:{{chem2|CH2\dCHCH3 + 1/2 O2 + CH3CO2H -> CH2\dCHCH2O2CCH3 + H2O}}

Hydrolysis of this acetate gives allyl alcohol. In alternative fashion, [[propylene]] can be oxidized to [[acrolein]], which upon [[hydrogenation]] gives the alcohol.

In principle, allyl alcohol can be obtained by [[dehydrogenation]] of [[Propan-1-ol|propanol]].

===Laboratory methods===

In the laboratory, [[glycerol]] reacts with [[oxalic acid|oxalic]] or [[formic acid]]s to give (respectively) [[dioxalin]] or glyceric formate, either of which [[decarboxylate]] and [[dehydrate]] to allylol.<ref>{{OrgSynth | volume = 1 | page = 15 | doi= 10.15227/orgsyn.001.0015 | title = Allyl alcohol | author =Oliver Kamm | author2 =C.

Allyl alcohols in general are prepared by [[allylic oxidation]] of [[allyl]] compounds, using [[Riley oxidation|selenium dioxide]] or [[Kharasch-Sosnovsky reaction|organic peroxide]]s. Other methods include carbon-carbon bond-forming reactions such as the [[Prins reaction]], the [[Morita-Baylis-Hillman reaction]], or a variant of the [[Ramberg-Bäcklund reaction]]. Hydrogenation of [[enone]]s is another route. Some of these methods are achieved by the [[Luche reduction]], [[Wharton reaction]], and the [[Mislow-Evans rearrangement]].

Allyl alcohol was first prepared in 1856 by [[Auguste André Thomas Cahours|Auguste Cahours]] and [[August Wilhelm von Hofmann|August Hofmann]] by [[hydrolysis]] of [[allyl iodide]].<ref name=Ullmann /> Today a

Allyl alcohol can be formed after [[trituration]] of [[Garlic|garlic (Allium sativum)]] cloves (producing from garlic in two ways: firstly by a [[Condensation reaction|self-condensation]] reaction of [[allicin]] and its [[Chemical decomposition|decomposition]] products such as [[Diallyl trisulfide|diallyl trisulphide]] and [[Diallyl disulfide|diallyl disulphide]] and secondly by the [[Chemical reaction|reaction]] between [[alliin]], the [[Precursor (chemistry)|precursor]] of [[allicin]], and [[water]]).<ref name=":0">{{Cite journal |last1=Lemar |first1=Katey M. |last2=Passa |first2=Ourania |last3=Aon |first3=Miguel A. |last4=Cortassa |first4=Sonia |last5=Müller |first5=Carsten T. |last6=Plummer |first6=Sue |last7=O'Rourke |first7=Brian |last8=Lloyd |first8=David |date=2005 |title=Allyl alcohol and garlic (Allium sativum) extract produce oxidative stress in ''Candida albicans'' |journal=Microbiology |volume=151 |issue=10 |pages=3257–3265 |doi=10.1099/mic.0.28095-0 |doi-access=free |issn=1465-2080 |pmc=2711876 |pmid=16207909}}</ref>

==Applications==

Allyl alcohol is converted mainly to [[glycidol]], which is a [[Reaction intermediate|chemical intermediate]] in the synthesis of [[glycerol]], glycidyl ethers, [[Ester|esters]], and [[Amine|amines]]. Also, a variety of [[Polymer|polymerizable]] esters are prepared from allyl alcohol, e.g. diallyl [[phthalate]].<ref name=Ullmann/>
