Presentation Transcript

  1. Chemistry Making alcohols and carboxylic acids

  2. Fermentaion • Fermenaion is the process of energy production in a cell under anaerobic conditions (without oxygen)Wine goes through fermentation. Yeast is added to a sugar and grape solution without any air. These Anaerobic conditions change yeast into glucose and carbon dioxide.

  3. The most advantageous temperature is 37 degrees Celsius.

  4. New Ways of making ethanol Reacting ethene with steam (C2H4 + H2O C4OH)They are passed through steam and mus be done at 300 degrees celsious at 60-70 atmosphere

  5. Carboxylic acids • Alcohols can be oxidise to make carboxylic acids. Methanoic acid is a carboxylic acid the fuctional group is is C=O-O-H.Things that use carboxylic acids are like vinegar.

  6. Esters are compounds formed from the reaction between alcohols and acids. The word 'ester' alone now signifies by common usage that the acid is an organic acid, but inorganic acids can also form esters - ATP is an example well-known to biology students, being a phosphate ester. Even halogenoalkanes can be regarded as inorganic esters, of alcohols and hydrochloric acid. This section is, however, confined to esters of organic acids RCOOR' where R can be hydrogen or an organic group:
