Ammonium Chloride
基本信息
应用 | Ammonium chloride finds its use as a flux in preparing metals for galvanizing, soldering or tin coating. While mainly referred as a nitrogen source fertilizer, it is also used in cleaning tip of soldering iron, hair shampoo as a thickening agent, some batteries as electrolyte, tanning, textile printing, dyeing, and cleaning products. In laboratories it is used to produce cooling baths and for producing buffers. Along with certain metals, it is used for effecting certain reductions in organic synthesis. It can be used as a precursor to ammonium cyanate, which is employed in the Wöhler synthesis of urea. It facilitates several organic transformations in a mild and efficient manner - for example in Ulmann coupling, cross-aldol condensation, Claisen rearrangement, reduction, thia-Michael addition and synthesis of several monocyclic, fused or spiro bicyclic nitrogen heterocycles. |
备注 | On heating it decomposes to ammonia and hydrogen chloride gas. |
