  • ESTERIFIC - ATION AND DEHYDRATON OF ALCOHOLS
    • ESTERIFIC - ATION
      • The reaction of an alcohol with a carboxylic acid to produce ester and water
        • Alcohol provids 'yl' and carboxylic acid provides 'anoate' part eg methanol and propanoic acid = meth'yl' porp'anoate'
      • Concentrated sulphuric H2SO4 acid is used as the catalyst
      • Heat
    • DEHYDRATION
      • Dehydration is an elimination reaction in which water is removed from a saturated (single bonds) molecule to produce an unsaturated (double bonds) molecule
      • Concentrated sulphuric H2SO4 or concentrated phosphoric H3PO4 may be used as catalysts
