DECOMPOSITION OF ETHERS
A process for producing propylene or butene is disclosed, comprising passing a stream comprising 10-70wt% of diisopropyl ether or 30-95wt% of di-sec butyl ether over an acid catalyst at a temperature of 180-300°C and a pressure of 0.01 - 3 bar g. Also disclosed is a process for producing either isop...

| description | A process for producing propylene or butene is disclosed, comprising passing a stream comprising 10-70wt% of diisopropyl ether or 30-95wt% of di-sec butyl ether over an acid catalyst at a temperature of 180-300°C and a pressure of 0.01 - 3 bar g. Also disclosed is a process for producing either isopropanol or 2-butanol, comprising contacting water and a propylene- or butene- containing feedstock in a hydration reaction zone with a hydration catalyst to produce a stream comprising either isopropanol and a by-product stream or 2-butanol and a by-product stream, passing said by-product stream over an acid catalyst at a temperature of 180-300°C and a pressure of 0.01 - 3 bar g to produce either propylene or butene, and then recycling said propylene or butene to the hydration reaction zone. |
