A filtered solution of barium hydroxide octahydrate reacted with an aqueous solution of boric acid to provide hydrated γ barium borate having a barium to boron ratio of 1:2 and having fine particle size. The hydrated γ barium borate was converted to the anhydrous γ form at about 300° to...
Efficient Wittig–Horner synthesis of acyclic α-enones with an asymmetric carbon at the γ-position using barium hydroxide β-Monosubstituted acylic α-enones with an asymmetric carbon at the γ-position: (E)-(5RS)-5-phenylhex-3-en-2-one, (4a), (E)-(6RS)-2,2-dimethyl-6-phenylhe.....

Horner-Wadsworth-Emmons reaction promoted by Ba(OH)2 is a mild and efficient method for the coupling of β-ketophosphonates with structurally complex, base-sensitive aldehydes. The barium hydroxide reaction is cleaner and faster to that achieved previously by the Masamune-Roush method (LiCl, Et3N...
Metallic barium is used for removal of residual gas in vacuum tubes and in alloys with nickel, lead, calcium, magnesium, sodium, and lithium. Barium compounds are used in the manufacture of lithopone (a white pigment in paints), chlorine, sodium hydroxide, valves, and green flares; in synthe...
