化學(xué)性質(zhì)

無色立方晶體或白色結(jié)晶粉末。味咸涼而微苦,酸式鹽。相對密度1.527。易溶于水及乙醇,溶于液氨,不溶于丙酮和乙醚。水溶液呈弱酸性,加熱時(shí)酸性增強(qiáng)。加熱至100℃時(shí)開始顯著揮發(fā),337.8℃時(shí)離解為氨和氯化氫,遇冷后又重新化合生成顆粒極小的氯化銨而呈白色濃煙,不易下沉,也極不易再溶解于水

用途及存儲(chǔ)

主要用于干電池、蓄電池、銨鹽、鞣革、電鍍、醫(yī)藥、照相、電極、粘合劑等。氯化銨也是一種速效氮素化學(xué)肥料,含氮量為24%~25%,屬生理酸性肥料。它適用于小麥、水稻、玉米、油菜等作物,尤其對棉麻類作物有增強(qiáng)纖維韌性和拉力并提高品質(zhì)之功效。但是,由于氯化銨的性質(zhì)決定并如果施用不對路,往往會(huì)給土壤和農(nóng)作物帶來一些不良影響。技術(shù)條件:執(zhí)行中華人民共和國國家標(biāo)準(zhǔn)GB-2946-82。
