- MAKING AND USING ALCOHOL
- HYDRATION OF ETHENE
- Catalysed by phosphoric acid H3PO4
- Steam
- High temperature 300C
- Moderate pressure 60atm
- The reaction is reversible and conversion of ethene is incomplete
- Overall 95% conversion is achieved
- The reaction is reversible and conversion of ethene is incomplete
- FERMENTATION
- The toxicity of the alcohol kills the yeast off at 14%
- This process is anaerobic - when air is present ethanal or ethanoic acid may be produced
- The toxicity of the alcohol kills the yeast off at 14%
- Yeast
- 37C
- Carbohydrates (sugar/starch)
- Alcoholic drinks - ethanol
- Cleaning fluids
- Perfumes
- Alternative fuel for cars - ethanol
- Methylated spirits - ethanol mixed with methanol and dye
- Fuel for racing cars - racing cars
- HYDRATION OF ETHENE
