Procedure

From the recycle, a 76% residual gas containing 95.2 grams of n-butenes (1.7 moles) and 30.4 grams of n-butene (0.52 mole) was removed per hours, was depressured to normal atmospheric pressure in the second separator and was discharged. In the second separator 140 grams (1.9 moles) of secondary butyl alcohol and 0.7-1.4 grams of di-sec. butyl ether were obtained per hour after removing the C4 -components in the form of a 77 to 89% crude alcohol still containing 10-22% water. The space-time yield of secondary butyl alcohol was 1.6 moles per liter of catalyst an hour, the selectivity being more than 99%.
