CAS: 540-37-4
分子式: C6H6IN
分子量: 219.02
中文名稱: 4-碘苯胺
對碘苯胺
英文名稱: 4-iodo-Benzenamine
4-Iodoaniline
p-iodo-anilin
4-iodobenzenamine
性質(zhì)描述: 白色結(jié)晶。熔點67-68℃。易溶于醇、醚和氯仿，微溶于水。
制備方法:由苯胺與碘在碳酸氫鈉存在下反應(yīng)而得。將苯胺、碳酸氫鈉加入水中，在劇烈攪拌下分次慢慢加入粉碎好的碘。加畢，繼續(xù)攪拌20min。如所得反應(yīng)液呈黃色可以加入少許亞硫酸氫鈉，使其褪色，然后過濾，得粗品。再經(jīng)乙醇重結(jié)晶得成品。

First Aid Measures
【Ingestion】Never give anything by mouth to an unconscious person. Get medical aid. Do NOT induce vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls of milk or water.
【Inhalation】Get medical aid immediately. Remove from exposure to fresh air immediately. If breathing is difficult, give oxygen. Do not use mouth-to-mouth respiration if victim ingested or inhaled the substance; induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device.
【Skin】Get medical aid. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse.
【Eyes】Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.
Handling and Storage
【Storage】Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. Store protected from light.
【Handling】Remove contaminated clothing and wash before reuse. Minimize dust generation and accumulation. Do not get on skin and clothing. Keep container tightly closed. Do not ingest or inhale. Use with adequate ventilation. Store protected from light.
Hazards Identification
【Inhalation】Causes respiratory tract irritation. Can produce delayed pulmonary edema.
【Skin】Causes skin irritation.
【Eyes】Causes eye irritation. May cause chemical conjunctivitis.
【Ingestion】May cause gastrointestinal irritation with nausea, vomiting and diarrhea. May be harmful if swallowed. May form methemoglobin which in sufficient concentration causes cyanosis.

Exposure Controls/Personal Protection
【Personal Protection】Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure.
【Respirators】A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever workplace conditions warrant a respirator's use.
【Exposure Effects】Effects may be delayed.
Fire Fighting Measures
【Fire Fighting】Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. To extinguish fire use water spray, dry chemical, carbon dioxide, or appropriate foam.
Accidental Release Measures
【Small spills/leaks】Sweep up, then place into a suitable container for disposal. Avoid generating dusty conditions. Provide ventilation.
