Unsaturated hydrocarbons can be obtained by dehydrating alcohols over alu-
minium oxide or kaolin catalysts. In the present investigation naturally occur-
ring gumbrin has been tested in regard to its suitability as a catalyst in the
dehydration of fermentation isoamyl alcohol.
Isopropyl ethylene of boiling point 24 degrees centigrade and crude methyl
ethyl ethylene of boiling point 30-34 degrees centigrade were isolated from the
reaction product with the yields of 5 percent and 38 percent, respectively, so
that gumbrin appears to be effective by virtue of its aluminium oxide content.
Granulated gumbrin in a layer 10 centimeters thick (in a glass tube 15 milli-
meters in diameter) was used. One hundred grams of isoamyl alcohol of boiling
point 130-131 degrees centigrade were passed through the catalyst-filled tube
during 2 hours. The temperature was maintained at 380-400 degrees centigrade.
The dehydration of isoamyl alcohol over aluminium oxide under identical condi-
tions leads to a yield of 8-12 percent isopropyl ethylene.
