Abstract

PURPOSE: To prepare boron trichloride in high yeild, by heat-treating boric acid supported on a granular active carbon in an inert gas atmosphere, and reacting the boric acid with chlorine gas to make the reaction proceed smoothly in a short time.
CONSTITUTION: A granular active carbon having about 1W50mm grain size and about 400W600m2/g specific surface area is impregnated with an aqueous solution of boric acid to support the boric acid in an amount of about 10W80pts.wt. based on 100pts.wt. active carbon. The resultant active carbon is then heated in an atmosphere of an inert gas, e.g. nitrogen gas, at 300W800°C to decompose and dehydrate the boric acid into diboron trioxide, which is then brought into contact with chlorine gas at about 300W800°C and converted into boron trichloride. The resultant boron trichloride is recovered from the active carbon by the well-known methods, e.g. condensation, distillation, etc.
