Description of key information

Additional information

A degradation category approach is applied, based on the very rapid and complete degradation (hydrolysis) of boron trichloride in water to form hydrochloric acid and boric acid. The description and justification of the category is presented in Section 13. The endpoint results of the degradation products are transcribed to boron trichloride.

The environmental fate depends in each case (also for humid air) on the presence of water or humidity. Therefore it is possible and necessary to describe the environmental fate of BCl3 by the fate of its degradation products.

The degradation of the inorganic compound boron trichloride is well understood. It degrades rapidly within 1 minute in water to hydrogen chloride and boric acid. Both inorganic degradation products can dissociate but are not further degradable.
