colorless square crystal or white granules or powder, tasteless. d 25 2.5142. Deliquescence. See light or open the air that the precipitation of iodine and yellow. 19 The product is soluble in 0.6 ml water, 0.5ml boiling water, 3.7ml ethanol, 1-5ml glycerol, 2.5ml methanol, insoluble in ether. Sublimation and decomposition occurred when heated to 551 °c.
neutralization method: iodine and red phosphorus are added to the reactor containing water, and the reaction is carried out under stirring. The reaction solution is carefully filtered and then distilled, the fractions at 125-130 ° C. Were collected to obtain hydroiodic acid. When ammonia gas was introduced to neutralize all of the hydroiodic acid to pH 8-9, the introduction of helium gas was stopped. The solution was filtered and evaporated in a water bath in vacuo until most of the crystals had precipitated. After cooling, centrifugal separation, drying at 50~60 C, prepared Ammonium iodide product. If the finished product is yellow in color, it can be treated by washing with alcohol.
is a raw material for the production of inorganic iodide. It can be used as a photographic film and a photographic substrate. The pharmaceutical industry is used in the manufacture of expectorants and diuretics. It is also used as a reagent for chemical analysis.
packaged in brown glass bottles, 0.5kg net weight per bottle. External use of wooden box container transport, each box containing 10 bottles. Packaging operations should be performed in a dark room or under red light. Should be stored in a cool, dark, dry warehouse. The mouth must be sealed. Protection against rain and sunlight during transport
She was found to be doing well. During loading and unloading, the glass bottle should be handled with care, and the impact and vibration are strictly prohibited to prevent breakage of the glass bottle. In case of fire, it can be suppressed by water, sand and all kinds of fire extinguishing. Toxicity and protection see iodine.
