Abstract
Disclosed is a continuous process for the production of tertiary butyl esters by the reaction of a ketene and tertiary butyl alcohol containing a finite concentration of water. The process may be carried out in an absorber reactor with continuous recovery and purification of products by distillation. This process provides high-purity tertiary butyl acetate without the production of unwanted by-products found in many strong acid catalyzed processes.
