Barium 4-hydrate

Barium hydroxide is the strongest base and has the greatest water-solubility of the alkaline-earth elements. Barium hydroxide (barium hydrate, caustic baryta) exists as the octahydrate [12230-71 -6], Ba(OH)2 8H20, the monohydrate [22326-55-2], Ba(OH)2 H20, or as the anhydrous [17194-00-2] material, Ba(OH)2. The octahydrate and monohydrate have sp gr 2.18 and 3.74, respectively. The mp of the octahydrate and anhydrous are 77.9 °C and 407°C, respectively. [Pg.480]

Ulsch2 has made some observations on the complete electrochemical oxidation of cane sugar to carbonic acid and water. In a sulphuric acid of 1.15 sp. gr., with the addition of manganese sulphate as an oxygen-carrier, about 98% of the theoretically calculated amount of carbonic acid is obtained. The oxidation at 40°-80° in barium-hydrate solution is also fairly complete, but not directly to carbonic acid oxalate appears also to be formed. [Pg.69]

The free base may be obtained by decomposing the sulphate with an exactly equivalent quantity of barium hydrate. On evaporating the resulting solution in vacuo, the base suddenly crystallises out in green leaflets, and is then found to have lost its easy solubility in water. [Pg.181]

This, the best known of the glycols, is prepared by the action of dry silver acetate upon ethylene bromide. The ether so obtained is purified by redistiUation, and decomposed by heating for some time with barium hydrate. [Pg.168]

BARIUM HYDRATE (17194-00-2) A strong base. Reacts with phosphorus, releasing phosphine gas. Violent exothermic reaction with maleic anhydride. Reacts violently with acids, chlorinated rubber (when heated), 1-nitropropane, zirconium powder or dust. Incompatible with organic anhydrides, acrylates, alcohols, aldehydes, alkylene oxides, substituted allyls, cresols, caprolactam solution, epichlorohydrin, ethylene dichloride, glycols, isocyanates, ketones, nitrates, nitromethane, phenols, vinyl acetate. Attacks chemically active metals (e.g. aluminum, magnesium, zinc). [Pg.151]

By contrast, the reaction of resorcinol with mesityl oxide (2-methylpent-2-ene-one) in the presence of barium hydrate at 150-170°C in vacuo (165-170mm Hg) with azeotropic removal of water during 5 hours has been claimed to afford a 34% yield of 2,2,4-trimethyl-5-hydroxy-2H-chromene rather than the 7-hydroxy isomer (ref.116). [Pg.304]

This was identical with the barium salt obtained by Siegfried from glycine, carbonic acid and barium hydrate. [Pg.33]

When one of the components of the mixture was an acid, the amount of it in the vapour was estimated by absorption in potash or barium hydrate, and when one component contained sulphur or a halogen, the process of analysis by means of soda-lime was adopted. The total quantity of liquid evaporated, rarely more than 2 grams, was ascertained by weighing the bulbs containing the mixture before and after the experiment. [Pg.80]
