Alchol Flashcards
How else can ethanol be made?
By reacting ethene with steam
What catalyst are the two gasses passed over?
Phosphoric acid catalyst
What type of reaction is this?
A hydration reaction
Word equation for making ethanol?
Ethene + Water = ethanol
Symbol equation for making ethanol?
C2H4 + H2O = C2H5OH
What is this method if making ethanol intended for?
It is intended for industrial use rather than alcoholic drinks
Ethanol made by Fermentation is what type of fuel? why?
A renewable fuel
- sugars needed coke from plants
- as long as new plants are planted after crops have been harvested
Ethanol made by the hydration of ethene is what type of fuel? Why?
It is non-renewable
-ethene needed come from cracking crude oil fractions (since crude oil is non-renewable this reaction is too)
General formula for alcohol?
Cn H2n+1 OH
What group do alcohols contain?
A hydroxyl group (OH)
What are alcohols named after?
The number of carbon atoms that they contain
What do alcohol names end in?
“Anol”
What is more sustainable fermentation or hydration of ethene?
Fermentation is more sustainable as it requires little energy and raw materials .
What are the down sides of fermentation?
It has a low percentage yield, atom economy and purity of the product
Methanol structure
CH3OH
