Properties and stability

Stable under normal temperature and pressure

Storage method

Store at room temperature.

Synthesis method

Dissolve phenanthrene in dry tetrahydrofuran Carbon chloride, heat to reflux, add bromine dropwise, and continue to reflux to escape the generated hydrogen bromide. The solvent is evaporated from the reaction solution under reduced pressure, and distillation under reduced pressure is continued to collect 177-190℃ (0.16kPa) fraction, which is 9-bromophenanthrene, yield 90%-94%.


Purpose

For organic synthesis
