ABSTRACT:
Process for the production of an aliphatic alcohol comprising reacting an olefin having from 2 to 4 carbon atoms with sulfuric acid to form an ester reaction product, diluting said product with water and steam stripping to remove a lower aliphatic alcohol overhead leaving a dilute sulfuric acid solution, concentrating said dilute sulfuric acid solution in a first stage indirect evaporator, recycling the steam generated in this first stage evaporator to the steam stripping step, further concentrating the sulfuric acid solution in a second stage direct heat evaporator to form a concentrated sulfuric acid solution and recycling said concentrated sulfuric acid solution for reaction with fresh olefin feed.
