# What is the boiling point of "octocrylene"?

This is a reasonably large molecule, and the boiling point is similarly large. The link reports a boiling point of $218$ ""^@C AT A PRESSURE of $1.5 \cdot m m \cdot H g$. That is its vapour pressure at this temperature $\equiv 1.5 \cdot m m \cdot H g$.
The normal boiling point, i.e. when its vapour pressure $\equiv$ $760 \cdot m m \cdot H g$ (this after all is the definition of the $\text{normal boiling point}$) would be very high, and it might not be obtainable without decomposition.
