Abstract
The reaction of a series of phenylalkanols of the general structure Ph[CH2]nOH (n= 2,3,4,5,6, and 10) in concentrated aqueous sulphuric acid at 25 °C has been studied. At acid concentrations >50% H2SO4 protonation dod sulphation of the alkanols take place. Half-protonation of 2-phenylethanol occurs at 75 ± 0% H2SO4. The rate constants for the sulphation of the alkanols and for the hydrolysis of the corresponding hydrogen sulphates increase with increasing acid concentration and so does the hydrogen sulphate/alkanol equilibrium ratio.
