hydroiodic acid การใช้

• Hydroiodic acid is currently listed as a Federal DEA List I Chemical.
• Hence hydroiodic acid cannot be concentrated past this point by evaporation of water.
• Aqueous hydrogen iodide is known as hydroiodic acid, which is a strong acid.
• Angelic acid reacts with hydrobromic acid and bromine producing hydrochloric and hydroiodic acids, respectively.
• Clandestine chemists react pseudoephedrine ( recovered from nasal decongestant pills ) with hydroiodic acid and red phosphorus under heat.
• For example, there is a weak bond between hydrogen and iodine in hydroiodic acid, making it a very strong acid.
• Hydrochloric acid, hydrobromic acid, hydroiodic acid, and hydroastatic acid are all strong acids, but hydrofluoric acid is a weak acid.
• Whereas hydroiodic acid solutions are stable, the hydronium-astatide solution is clearly less stable than the water-hydrogen-astatine system.
• In the Monsanto process, carbon monoxide and methanol react in the presence of a homogeneous rhodium catalyst and hydroiodic acid to give acetic acid.
• NiI 2 readily hydrates, and the hydrated form can be prepared by dissolution of nickel oxide, hydroxide, or carbonate in hydroiodic acid.
• In the following year he studied the action of hydroiodic acid on glycerol, and showed that the product was isopropyl-and not propyl iodide.
• Due to its listed status and closely monitored sales, clandestine chemists now use red phosphorus and iodine to generate hydroiodic acid " in situ ".
• According to the 1911 Encyclop鎑ia Britannica, hydantoin can also be synthesized either by heating allantoin with hydroiodic acid or by " heating bromacetyl urea with alcoholic ammonia ".
• Hydrogen iodide and hydroiodic acid are, however, different in that the former is a gas under standard conditions, whereas the other is an aqueous solution of said gas.
• "' Hydrobromic acid "'is a pK a of  " 9, making it a stronger acid than hydrochloric acid, but not as strong as hydroiodic acid.
• As first reported by Kiliani, hydroiodic acid reduction of sugars and other polyols results in the reductive cleavage of several or even all hydroxy groups, although often with poor yield and / or reproducibility.
• Iodides can be made by reaction of an element or its oxide, hydroxide, or carbonate with hydroiodic acid, and then dehydrated by mildly high temperatures combined with either low pressure or anhydrous hydrogen iodide gas.
• Commercial so-called " concentrated " hydroiodic acid usually contains 48 57 % HI by mass; the solution forms an azeotrope with boiling point 126.7 癈 at 56.7 g HI per 100 g solution.
• "The Daily Beast " reported that Nakoula was arrested by the Los Angeles County Sheriff's Department in 1997 after being pulled over and found to be in possession of hydroiodic acid and $ 45, 000 in cash.
• In 1907 the process was still further improved by reducing 2-( 2'- hydroxypropyl ) pyridine with phosphorus and hydroiodic acid at 125 癈 and treating the product with zinc dust and water, then reducing the product with sodium in ethanol.
