Boron trifluoride is a colorless gas which has a persistent, irritating, acidic odor and which hydrolyzes in moist air to form dense white fumes. It is shipped as a nonliquefied compressed gas at varying pressures up to 2000 psig (13 790 kPa).
The #1 Choice for BF3 Gas and Complex - For over 70 years, Honeywell has been the trusted source for Boron Trifluoride \(BF3\) supply. We provide expertise in the manufacture, transport, delivery, and safe handling of BF3.
23 lip 1999 · Liquid HF is a weak acid but the addition of BF 3 greatly increases the acidity of the solution. In order to gain insight into this phenomenon we have used density functional theory to investigate the clusters BF 3 + (HF) 1–7. We find that BF 3 + (HF) 1–3 are weakly bound Van der Waals complexes, as indicated by long intermolecular B–F distances.
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.
IMMEDIATELY give the victims milk or water to dilute the hydrofluoric acid: children up to 1 year old, 125 mL (4 oz or 1/2 cup); children 1 to 12 years old, 200 mL (6 oz or 3/4 cup); adults, 250 mL (8 oz or 1 cup).
20 sty 2016 · Boron trifluoride monohydrate is an excellent Brønsted acid catalyst system for a wide range of reactions. It is a non-oxidizing acid catalyst prepared easily by bubbling BF 3 into water. We have found boron trifluoride monohydrate/sodium azide combination to be an efficient reagent system for aromatic electrophilic amination.
BF3-Methanol provides a convenient methanol-catalyst system which, when used in excess with heating, quickly and quantitatively converts carboxylic acids to their methyl esters.
