Versuchsvorschrift
The procedure described in comparison Example 1 was altered so that by use of an additional dosing pump 54 kgs of the process water (total amount 204 kgs) were charged to the n-butane/n-butene mixture (feedgas and recycle gas=3,000 kgs/h) and transferred to the evaporator. Employing the same conditions as in comparison Example 1 (155° C. to 160° C., 70 bar) a temperature of 155° C. to 162° C. could be maintained in the reactor without additional heating or cooling. In the sump of a column, average amounts of 201.3 kgs (2,720 moles) of sec. butyl alcohol and 2.1 kgs (16.2 moles) of di-sec. butyl ether were obtained per hour as an approx. 99% purity crude alcohol. 101.5 kgs of n-butene and 46.4 kgs of n-butane were obtained as an approx. 59% mixture.
