Abstract
Ethers are cracked to olefins using a gamma-alumina catalyst in the presence of ammonia. The use of ammonia improves the selectivity to linear alpha olefins in comparison to cracking reactions in the absence of ammonia. The use of ammonia is convenient in comparison to known processes which employ alumina which as been treated with an amine. A preferred process produces octene-1 from 1-methoxyoctane.
