Production of 2-phenylethanol:
Many syntheticmethods are known for preparing 2-phenylethanol.
The following are currently of industrial importance:
1) Friedel–Crafts reaction of benzene and ethylene oxide:
In the presence of molar quantities of aluminum chloride, ethylene oxide reacts with benzene to give an addition product, which is hydrolyzed to phenylethyl alcohol:
Friedel–Crafts reaction of benzene and ethylene oxide.
Formation of by-products, such as 1,2-diphenylethane, is largely avoided by using an excess of benzene at low temperature.
Special purification procedures are required to obtain a pure 2-phenylethanol that is free of chlorine and suitable for use in perfumery.
2) Hydrogenation of styrene oxide: Excellent yields of 2-phenylethanol are obtainedwhen styrene oxide is hydrogenated at low temperature, using Raney nickel as a catalyst and a small amount of sodium hydroxide.
Synthesis of 2-phenylethanol:
2-phenylethanol is prepared commercially via two routes.
Most common is the Friedel-Crafts reaction between benzene and ethylene oxide in the presence of aluminium trichloride.
C6H6 + CH2CH2O + AlCl3 → C6H5CH2CH2OAlCl2 + HCl
The reaction affords the aluminium alkoxide that is subsequently hydrolyzed to the desired product.
The main side product is diphenylethane, which can be avoided by use of excess benzene.
Hydrogenation of styrene oxide also affords 2-phenylethanol.
Laboratory methods:
2-phenylethanol can also be prepared by the reaction between phenylmagnesium bromide and ethylene oxide:
C6H5MgBr + CH2CH2O → C6H5CH2CH2OMgBr
C6H5CH2CH2OMgBr + H+ → C6H5CH2CH2OH + MgBr+
2-phenylethanol can also be produced by biotransformation from L-phenylalanine using immobilized yeast Saccharomyces cerevisiae.
2-phenylethanol is also possible to produce 2-phenylethanol by the reduction of phenylacetic acid using sodium borohydride and iodine in THF.
