The initial mixture contains nbutanol / acetic acid, in the molar proportions 4.97/1. The catalyst is sulfuric acid (0.032% by mass). The reaction rate is proportional to the square of the acetic acid concentration and the rate constant at the working temperature (100°C) is 0.0174 L mol-1 min-1. The density of the mixture is assumed to be constant ( = 0.75 kg/L), as is the volume of the charge. The molar masses are as follows: MAcAc = 60 g/mol; MBuOH = 74 g/mol. 1) Determine the time required for a 50% conversion of acetic acid.
Production of n-butyl acetate
We wish to produce, in batch, n-butyl acetate by esterification of butyl alcohol in the presence of sulfuric acid (catalyst). The initial mixture contains nbutanol / acetic acid, in the molar proportions 4.97/1. The catalyst is sulfuric acid (0.032% by mass).
