The Family

In the gas phase, acetic acid reacts with hydrogen bromide in the temperature range 412-492� to give methyl bromide, carbon monoxide, and water. The reaction is first order in each reagent, and the variation of rate constant with temperature is described by the equation �� ����������������� k2 = 1011.67exp(-30400/RT) ml mole-1 sec-1 Possible transition states for the reaction are examined. A mechanism involving an intermediate of the type CH3CO+Br- is possible if the reaction is of the family represented by the hydrogen bromide catalysed decompositions of trimethylacetic, isobutyric, and propionic acids.

Order Form

In the gas phase methyl acetate reacts with hydrogen bromide over the range 419-497� to give methyl bromide, carbon monoxide, and methanol. Rate constants first order in both ester and hydrogen bromide are calculated from initial slopes, and are described by the equation �������������������� k2 = 1012.29exp(-32312/RT) ml mol-1 s-1 Kinetic data depart from this second-order form at early stages of the reaction. The addition of methanol can reduce the value of k2 to zero. A mechanism involving the reversible step : ������������������������ CH3COOCH3+HBr ↔ CH3OH+A* is proposed. The intermediate reacts with isobutene to form mesityl oxide, and is considered identical with that formed in the reaction of acetic acid with hydrogen bromide.
