Overview
BF3 is a non-flammable compressed gas packaged and shipped in cylinders under high pressure. It is one of the strongest Lewis acids, which are also known as electron pair acceptors. In gas form, it reacts with chemicals containing oxygen, nitrogen, sulfur, and other electron pair donors to form addition or coordination compounds. It is extensively used as an acidic catalyst for organic synthesis reactions.
