Description

The simplest polycondensed aromatic hydrocarbon, a solid crystalline substance with a characteristic odor. Doesn't form water hydrates.

Where to buy

Can be bought in hardware store (moth repellent).

Influence of temperature

Can sublimate at any temperature, but best results are achieved as ~50-60°C.

Notes

Crystals can grow by both solution evaporation and by sublimation in closed vessel.
