  • Cracking 1-ethers over unmodified ?-alumina
    Patent number: 7576250
    Abstract: 1-Ethers may be cracked over untreated ?-alumina having a pore volume of more than 1.0 cc/g and an average pore diameter of more than 150 angstroms (?) at a temperature from 250 to 350° C. and a pressure from 10 to 200 kPa at high conversions and good selectivity to produce the corresponding 1-alkene. The process is particularly useful to produce 1-octene from 1-methoxyoctane.
    Type: Grant
    Filed: February 21, 2007
    Date of Patent: August 18, 2009
    Assignee: Nova Chemicals (International) S.A.
