화학적 성질 · 1건

Hydrogen iodide is a colourless to yellow/brown with an acrid odour non-flammable gas. Hydrogen iodide is incompatible with water and other halides. Hydrogen iodide, upon contact with moisture in air, releases dense vapours. Hydrogen iodide reacts with water to form corrosive acids and reacts violently with alkalis. Most metals corrode rapidly on contact with wet hydrogen iodide, and prolonged exposure of hydrogen iodide to fire or intense heat has been reported to cause the container to rupture and rocket.

If material involved in fire: Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.) Cool all affected containers with flooding quantities of water. Do not apply water to point of leak in tank car or container. Apply water from as far a distance as possible. Do not use water on material itself. If large quantities of combustibles are involved, use water in flooding quantities as spray and fog. Use water spray to knock-down vapors. /Hydrogen Iodide, anhyrous/

Storage Conditions · 3건

Hydroidic acid must be stored to avoid contact with strong acids (such as hydrochloric, sulfuric and nitric), chemically active metals (such as potassium, sodium, magnesium and zinc), and strong oxidizers (such as chlorine, bromine, and fluorine) since violent reactions occur. Store in tightly closed containers in a cool, well vented area away from heat and moisture. Protect storage containers from physical damage. Procedures for the handling, use and storage of cylinders should be in compliance with OSHA 1910.101 and 1910.169 as with the recommendations of the Compressed Gas Association.

MATERIALS THAT ARE TOXIC AS STORED OR THAT CAN DECOMPOSE INTO TOXIC COMPONENTS ... SHOULD BE STORED IN A COOL WELL VENTILATED PLACE, OUT OF THE DIRECT RAYS OF THE SUN, AWAY FROM AREAS OF HIGH FIRE HAZARD, & SHOULD BE PERIODICALLY INSPECTED. INCOMPATIBLE MATERIALS SHOULD BE ISOLATED. ...

Keep protected from light and air, preferably not above 3 °C.

Cleanup Methods · 1건

Evacuate and restrict persons not wearing protective equipment from area of spill or leak until cleanup is complete. Remove all ignition sources. Ventilate area of spill or leak. Neutralize with chemically basic substances such as sodium bicarbonate, soda ash, or slaked lime. Absorb liquids in vermiculite, dry sand, earth, peat, carbon, or a similar material and deposit in sealed containers. Keep this chemical out of confined spaces, such as a sewer, because of the possibility of an explosion, unless the sewer is designed to prevent the build up of explosive concentrations. It may be necessary to contain and dispose of this chemical as a hazardous waste. If material or contaminated runoff enters waterways, notify downstream users of potentially contaminated waters. Contact your Department of Environmental Protection or your regional office of the federal EPA for specific recommendations. If employees are required to clean-up spills, they must be properly trained and equipped. OSHA 1910.120(q) may be applicable.

Hydroiodic acid is the colorless solution formed when hydrogen iodide gas dissolves in water. It is prepared by reaction of iodine with hydrogen sulfide or hydrazine, or by an electrolytic method. Typically commercial hydroiodic acid contains 40-55% HI.

By catalytic union of the elements. Also prepd by treating concn hydriodic acid soln with phosphorus pentoxide. /Hydrogen iodide gas/

... /Hydrogen iodide gas/ cannot be prepared using strong acids because it is readily oxidized; therefore, it must be prepared from a weak acid and iodine, or by the hydrolysis of certain iodides. Hydriodic acid is the colorless solution formed when hydrogen iodide gas dissolves in water, and at commercial strength, typically contains 47% hydrogen iodide.

Hydriodic acid: ACTIVE

응용 분야 · 3건

개요‘Iodine’ is derived from iodes, a Greek word meaning violet. It is a member of the halide family and hydrogen iodide is considered a strong acid.

용도Hydriodic acid is used in the manufactureof iodides, as a reducing agent, and indisinfectants and pharmaceuticals.

일반 설명A colorless to yellow liquid with a pungent odor. Consists of a solution of hydrogen iodide in water. Fumes irritate the eyes and mucous membranes. Corrosive to metals and to tissue. It is prepared by the reaction of iodine and hydrosulfuric acid or by the reaction of phosphorus plus iodine plus water followed by distillation. Concentrated hydroiodic acid reacts with the oxygen of the air to form free iodine, which gives a brownish color to the solution. It also gives an idea of the reducing nature of this acid. It is an important reagent in organic chemistry and is used commercially in the preparation of iodides.

물의 요오드화(iodide) 수소 요오드화(iodide)기체의 흡수 또는 황화수소 요오드화(iodide)의 작용에 의해 준비됨. (요오드화수소산(Hydriodic acid)) 요오드화(iodide)과 수소의 촉매반응이나 농축된 오산화린(phosphorous pentoxide)과 요오드화수소(Hydroiodic)산액에 의해 준비 요오드화(Hydroiodic) 수소산은 수계에서 수소 요오드화(iodide) 기체가 용존할 때 무색액의 형태임. 이것은 아이오딘(iodine)과 황화수소나 하이드라진(hydrazine)이나 전해질방법에의한 반응에 의해 준비됨. 일반적 상업 수소산은 40-55 %의 아이오딘화수소(HI)를 포함 원소의 촉매. 또한 요오드화수소산(hydriodic acid)액과 오산화린(phosphorus pentoxide)처리에 의해 준비됨. (수소 요오드화(iodide) 기체) 수소 요오드화(iodide) 기체는 이것의 쉽게 산화됨으로 인해 강한 산사용으로 준비될수 없음; 따라서 약산과 요오드화(iodine)이나 특정 요오드화(iodide)의 가수분해로부터 준비되어야함. 요오드화 수소산은 수계 및 일반적으로 47 %의 수소요오드화(iodide)을 포함하는 상업용에서 수소 요오드화(iodide) 기체가 용존할 때 무색액의 형태

Hydrogen iodide is prepared by direct combination of hydrogen and iodinevapor in the presence of platinum catalyst: H2 + I2 → 2HI The compound is produced in commercial scale by reaction of iodine withhydrazine or hydrogen sulfide: 2I2 + N2H4 → 4HI + N2 I2 + H2S → 2HI + S Hydriodic acid may be prepared by dissolving hydrogen iodide gas in water.The acid also may be obtained by electrolysis of iodine solution or by passinghydrogen sulfide into a suspension of iodine in water and boiling to expelexcess sulfide. After boiling, the precipitated sulfur is removed by filtrationthrough fritted glass plate or glass wool. Hydriodic acid in small quantities may be prepared by adding water care-fully to a solid mixture of red phosphorus and iodine. Technical grade hydriodic acid is a 47% HI solution and usually has abrown color due to the presence of free iodine, produced by air oxidation of HI.Hydriodic acid should be stored in the dark to prevent photochemical decom-position, and free from air to prevent oxidation. The addition of 1.5%hypophosphorus acid (H3PO2) prevents oxidative decomposition. Hydriodic acid also is commercially sold at 57% (azeotropic concentration)and 10% aqueous solutions.
