Title: Enthanol in Wacker
Post by: PurpleSmurf on March 02, 2002, 12:48:00 PM

Can Ethanol be substituted for methanol or DMF in the Wacker oxidation, with no other alterations in chemicals or procedure?  Thanks a bunch

Ethanol has been used successfully in O2 Wacker oxidations.

But with pressure right ?

Why would pressure be required?  Ethanol boils at a higher temperature than methanol, is there something I'm missing here?

There are two different O2 wackers.  One uses pressurized O2.

Sunlight: Yes medium pressure was used- 50 to 100 psi.  Reactor was initially charged to 100psi and recharged after it dropped to 50psi.
