GREY METALLIC POWDER | [Uses]
Nickel Boride is used as a selective hydrogenation catalyst, desulfurization catalyst; reduces nitro and other functional groups;
dehalogenation catalyst; hydrogenolysis catalyst. | [Preparation]
Preparative Methods of Nickel Boride: to a stirred suspension of 1.24 g (5 mmol) of powdered Nickel(II) Acetate in 50 mL of
95% ethanol is added 5 mL of a 1 M solution of Sodium Borohydride in 95% ethanol at room temperature
(control frothing). Stirring is continued until the gas evolution ceases (usually 30 min). The flask is used directly
in the hydrogenation. This catalyst is nonpyrophoric. | [storage]
Caution must be taken in handling nickel salts. Ingestion of soluble nickel
salts causes nausea, vomiting, and diarrhea. Nickel chloride has an LD50 (iv) = 40-80 mg kg-1 in dogs. Many
nickel salts will sublime in vacuo. Nickel metal is carcinogenic and certain nickel compounds may reasonably be
expected to be carcinogenic. |
