What is C3H7OH? Important knowledge about C3H7OH

  1. Definition of C3H7OH:
    C3H7OH, also known as propanol or propylic alcohol, is a multi-functional alcohol with a molecular formula of C3H7OH. Propanol has 2 isomers, which are propan-1-ol (n-propanol) and propan-2-ol (isopropanol). In English, it is called Propanol. C3H7OH contains 3 carbon atoms, 7 hydrogen atoms, and 1 oxygen atom, with the atomic masses of 12, 1, and 16 respectively. The C3H7OH molecule is formed from covalent bonds between these atoms.

  2. Properties of C3H7OH:
    2.1 Physical properties: Propanol is a colorless liquid with a distinctive aroma of alcohol. Its pH is almost neutral.
    2.2 Chemical properties: Propanol can react with metals, acids, and non-metals, but it is primarily used for mirror coating reactions (the reaction between propanol and dinitrogen pentoxide).

  3. Common chemical equation:
    C3H7OH + 3O2 -> 3CO2 + 4H2O: This is the complete oxidation reaction of propanol.

  4. Preparation of C3H7OH:
    4.1 Laboratory preparation: Propanol can be prepared from propene through a reaction with water in an acidic environment.
    4.2 Industrial preparation: In industry, propanol is typically produced from propene through a reaction with steam at high temperatures, under pressure, and in the presence of a catalyst.
