Knowledge of the kinetics of the reaction of butanol and acetic acid catalyzed by sulfuric acid, coupled with vapor-99.92% pure, and had a water content of 0.080% and a boiling range of 116.6-117.7°C. Butyl acetate was prepared from commercial ester by treatment with acetyl chloride, followed by distillation and phosphorus pentoxide purification (3) and redistillation; its boiling point was 125.5°C. and its ester content was 99.80% by saponification in the cold with aqueous alkali.
