Ammonium chloride (abbreviated li NH₄Cl) yog ib qho inorganic compound nrog cov tshuaj formula NH₄Cl. Nws yog ammonium ntsev ntawm hydrochloric acid thiab feem ntau yog los ntawm cov khoom lag luam alkali kev lag luam. Ammonium chloride zoo nkaus li me me, dawb los yog daj me ntsis, square lossis octahedral crystals, muaj nyob rau hauv ob hom hmoov thiab granular. Granular ammonium chloride tsis tshua muaj hygroscopic thiab yooj yim rau khaws cia, thaum hmoov ammonium chloride feem ntau siv los ua cov chiv chiv rau kev tsim cov chiv chiv.
Ammonium chloride yog yooj yim soluble nyob rau hauv dej thiab glycerol, me ntsis soluble nyob rau hauv ethanol, thiab insoluble nyob rau hauv benzene thiab ether. Nyob rau hauv cov huab cua qhuav, nws yog nquag efflorescence thiab poob ntawm cov dej siv lead ua, thaum nyob rau hauv cov huab cua ntub, nws undergoes hydrolysis ua rau hydrochloric acid corrosion. Tag nrho cov ntsev ammonium muaj cov khoom siv dav dav ntawm cov hauv paus, tab sis ammonium chloride nws tus kheej yog cov tshuaj acidic. Nws yog yooj yim decomposed thaum cua sov thiab reacts nrog acids los tsim ammonium ntsev. Thaum kub hnyiab, nws tuaj yeem tsim cov roj ntsha uas muaj zog xws li nitrogen oxides thiab ammonia. Nyob rau hauv cov txheej txheem kub-dip galvanizing, nws yog feem ntau tov nrog zinc chloride siv.
