Production Methods of 1,4-Butanediol Solid
1,4-butanediol solid is primarily produced through two methods: the Butane Oxidation Process and the Propylene Oxidation Process.
Butane Oxidation Process
The Butane Oxidation Process is the most common method for producing 1,4-butanediol. It involves the catalytic oxidation of butane (C4H10) with oxygen (O2) in the presence of a catalyst. The overall reaction can be represented as:
C4H10 + 5/2 O2 鈫?C4H8O2 + 2 H2O
This process requires high temperatures and pressures, typically around 200-300掳C and 20-30 bar, respectively. The catalyst used in this process is usually a precious metal, such as palladium or platinum, supported on a carrier material like alumina or zeolite.
Propylene Oxidation Process
The Propylene Oxidation Process is another method for producing 1,4-butanediol. It involves the catalytic oxidation of propylene (C3H6) with oxygen (O2) in the presence of a catalyst. The overall reaction can be represented as:
C3H
