Barium monoxide

Pyridine. The analytical reagent grade pyridine will satisfy most requirements. If required perfectly dry, it should be refluxed over potassium or sodium hydroxide pellets or over barium monoxide, and then distilled with careful exclusion of moisture (compare Fig. 77, 47, 2). It is hygroscopic, and forms a hydrate of b.p. 94-5°. Pure pyridine has b.p. 115-5°/760 mm. [Pg.175]

Further effusion mass spectrometry work has been carried out on barium monoxide from a variety of Knudsen cells made of molybdenum, or graphite, or alumina, or platinum to study the reaction of the monoxide with the cell material. The ionic species Ba, BaO, and Ba202 were detected in the vapour, but, contrary to the results of other investigations, no BajOs ions were observed. The vapour pressure of barium monoxide is given by ... [Pg.58]

Oxids.—Barium Monoxid—Baryta—BaO—152.8—is prepared by calcining the nitrate. It is a grayish-white or white, amorphous, caustic solid. In air it absorbs moisture and COa, and combines- with HiO as does CaO. [Pg.203]

Barex The trade name for BP Chemical International s (Sohia Division) family of acrylonitrile (AN) copolymerized styrene plastic. It was the first technically and commercially successful carbonated beverage bottle to be produced and was used in producing the first Coca-Cola stretched injection blow-molded bottles. See Coca-Cola bottle, barium oxide (BaO) A white to yellow powder that melts at 192°C. It forms a hydroxide with water and is used as a dehydrating agent. Also called barium monoxide or barium protoxide. [Pg.106]
