PDF	Kinetics of transesterification of methyl acetate and n-octanol The calculated activation energy for methyl acetate with n-octanol transesterification (Ea1=68 48 kJ mol−1 Table 2) is higher than the value of methyl

MeOAc hydrolysis is an endothermic reaction ( Δ H ° 298 = 10.87 kJ/mol ) so high temperature facilitate chemical equilibrium to forward direction.
However, MeOH dehydration is an exothermic reaction ( Δ H ° 298 = − 35.27 kJ/mol ), and the heat could provide the duty of reboiler and promote MeOAc conversion as well.

What is the activation energy of methyl acetate?

The calculated activation energy for methyl acetate with n-octanol transesterification (Ea1=68.48 kJ mol−1, Table 2) is higher than the value of methyl acetate with n-butanol over NKC-9 [5], and is similar to the value reported in literature for methyl acetate with n-Butanol using Amerlyst 15 as catalyst [3].

What is the activation energy of the hydrolysis of ethyl acetate?

The initial rate constant at 25°C was measured as 0.1120 1./mol./sec. and the activation energy was 11.56 kcal./mol., values agreed well with those of previous studies.

What is the reaction of the hydrolysis of methyl acetate?

Methyl acetate undergoes hydrolysis, in the presence of an acid (HCl, for example), to give acetic acid and methyl alcohol.
In the presence of an acid, this reaction should be of second order, since two molecules are reacting.
But, it is found to be first order.
