Compound |
Heat of combustion (kJ/g) |
Calculated for "monomer" (kJ/g) |
Calculated for polymer (see note) (kJ/g) |
Cotton | 18.855 | 14.2 | 15.8 |
Cellulose acetate | 17.598 | 16.2 | 17.2 |
Cellulose Nitrate | ? | 5.2 | 5.5 |
Note: For the calculated values, the weight of the monomer minus the weight of one water molecule was used to represent the repeat unit in the polymer. Also, for combustion reactions, the values are given without the negative sign since it is assumed that we know that combustion releases heat.
