Conclusions 1. The kinetic laws for the hydrobromination of n-C3H7OH by hydrogen bromide at 80°C in a solution with and without additions of H2SO4 have been investigated. 2. A method is proposed for taking account of the reduction in the acidity of the medium due to the consumption of HBr from the solution during the hydrobromination reaction. The kinetic curves are described by a second order equation for the reactions involving the formation of n-C3H7Br and its hydrolysis. 3. When the reagents are mixed, an equilibrium is rapidly achieved between n-C3H7OH, H2SO4, and n-C3H7OSO2OH. The alkyl acid is unreactive in the hydrobromination of n-propyl alcohol. 4. The rate of reaction, referred to the current concentrations of HBr and the alcohol which is not bound up in the alkyl acid, varies proportionally to the acidity of the medium h0. A dilute solution of the strong acid in the mixture was chosen as the standard state. At 80°C, this law is obeyed up to 4.2 mole/liter n-propanol in the solution.
