Combustion of Xylene
C8H10 + 10.5O2 → 8CO2 + 5H2O
Overview
Xylene (dimethylbenzene) burns with a smoky yellow flame. Xylene exists as three isomers (ortho, meta, para), all with similar combustion properties. It is a major component of paint thinner and an important industrial solvent.
Participants
| Role | Substance | Coefficient | State |
|---|---|---|---|
| Reactant | Xylene C₈H₁₀ | 1 | (l) |
| Reactant | Oxygen O | 10 | (g) |
| Product | Water H₂O | 5 | (l) |

Everyday Example
Xylene is a common solvent in paint thinners and some cleaning products. It has a sweet smell but is harmful to inhale.
Industrial Importance
Para-xylene is oxidized to terephthalic acid, the precursor for PET plastic (water bottles and polyester fabric). Over 60 million tonnes of xylene are produced annually.
