A
OH
2
Q
How can ethanol be manufactured?
A
Fermentation or catalytic hydration
3
Q
What are the conditions for the fermentation of glucose using yeast enzymes to produce ethanol?
A
The absence of oxygen at 30 degrees
4
Q
What is catalytic hydration?
A
Reacting ethene with steam in the presence of a phosphoric acid catalyst at 300 degrees and 60-70 atm
5
Q
Why does fermentation occur in the absence of oxygen?
A
If oxygen is present during fermentation, enzymes respire aerobically producing water and carbon dioxide instead of ethanol
