alcohols (2)

• uses of alcohol

  • mouth wash
  • solvents
  • fuel
• the functional group of alcohols is OH
• making alcohol using hydration

  • positive : produces a high yield
  • negative : ethene is from crude oil , a non renewable source
  • negative : high temperature requires alot of energy
• another way of making alcohol is FERMENTATION

  • glucose mixes with yeast to produce ethanol and carbon dioxide
  • it needs to be 30 degrees
  • and it has to be in anaerobic conditions
• using fermentaion of sugar

  • positive : the glucose is from plants , a renewable source
  • positive : low temperature requires less energy
  • negative : the ethanol is an aqueous solution so you need to purify it by distillation which requires energy
