New cards

what catalyst is needed for ethene + steam

phosphoric acid catalyst

2
New cards

what are the (dis)advantages of making ethanol with steam + ethene

  • cheap

  • not much is wasted

  • ethene made from crude oil = non renewable source (will run out soon)

3
New cards

what type of reaction is ethene + steam?

addition reaction because water is added to molecule

4
New cards

why is it important to be in anaerobic conditions during fermentation?

oxygen converts ethanol to carboxylic acid (vinegar)

5
New cards

3 uses of ethanol

  • alcoholic drinks

  • burned to be used as biofuel

  • chemical feedstock to make other organic compounds

6
New cards

write the symbol equation for ethanol produced by fermentation

C6H12O6 → (yeast enzymes) → 2C2H5OH → 2CO2

7
New cards

how can ethanol be converted to ethanoic acid?

add potassium dichromate and dilute sulphuric acid then heat

8
New cards

how is ethanol be naturally converted to ethanoic acid

microbes in the air react it with oxygen
