Barium hydroxide is occasionally used in organic synthesis as a strong base, for example for the hydrolysis of esters [8] and nitriles, [9] [10] [11] and as a base in aldol condensations. There are several uses for barium hydroxide such as to hydrolyse one of the two equivalent ester groups in dimethyl hendecanedioate.
The use of barium during pregnancy is safe for the baby; however, X-rays may result in harm. [4] Barium sulfate suspension is typically made by mixing barium sulfate powder with water. [1] It is a non-iodinated contrast media. [5] Barium sulfate has been known since the Middle Ages. [6] In the United States it had come into common medical use ...
Baralyme is a mixture of 80% calcium hydroxide and 20% barium hydroxide compounds [1] [2] [3] that is used as an alternative to soda lime to absorb the exhaled carbon dioxide in a closed circuit anesthetic system.
The use of gold compounds has decreased since the 1980s because of numerous side effects and monitoring requirements, limited efficacy, and very slow onset of action. Most chemical compounds of gold, including some of the drugs discussed below, are not salts, but are examples of metal thiolate complexes.
The GI cocktail is a mixture of a viscous anesthetic, an antacid, and an anticholinergic. [1] [2] Common viscous anesthetics use are viscous lidocaine or xylocaine.Common antacids used are magnesium hydroxide, aluminum hydroxide, or simethicone (more commonly known as Mylanta or Maalox). [3]
This precipitation reaction is used in chlor-alkali plants to control the sulfate concentration in the feed brine for electrolysis. Oxalate effects a similar reaction: BaCl 2 + Na 2 C 2 O 4 → 2 NaCl + BaC 2 O 4. When it is mixed with sodium hydroxide, it gives barium hydroxide, which is moderately soluble in water. BaCl 2 + 2 NaOH → 2 NaCl ...
Barium, typically as barium nitrate imparts a yellow or "apple" green color to fireworks; [30] for brilliant green barium chloride is used. Barium peroxide is a catalyst in the aluminothermic reaction for welding rail tracks. It is also a green flare in tracer ammunition and a bleaching agent. [31] Barium titanate is a promising electroceramic ...
Barium oxide, also known as baria, is a white hygroscopic non-flammable compound with the formula BaO. It has a cubic structure and is used in cathode-ray tubes , crown glass, and catalysts. It is harmful to human skin and if swallowed in large quantity causes irritation.
