Chlorium chloride cas: 12125-02-9

Amonium chloride, ((kalasi ya mafakitale) clorium cloride (yotchedwa "chloramene", kiloran mchenga, NH4CL) ndi ufa woyera. Zimakoma mchere komanso zowawa pang'ono ndipo zimakhala za asidi. Kuchuluka kwake ndi 1.527. Imasungunuka m'madzi, ethanol ndi ammonia amadzimadzi koma insuluble mu acetone ndi ether. Njira yothetsera matendawa ndi yofooka acidic, ndipo acidity yake imakulitsidwa potentha. Atatchera mpaka 100 ° C, imayambanso kukhala ndi lolankhula kwambiri, ndipo pofika 337.8 ° C, zimapangitsa kuti hydrogen chloride, zomwe zimaphatikizidwa, zomwe zimaphatikizidwa, zidzaphatikizanso zochulukirapo za ammonium chloride ndi oyera utsi Izi sizophweka kumira komanso zovuta kwambiri kuti zisungunuke m'madzi. Atatchera mpaka 350 ° C, idzagonjera komanso pomwe 520 ° C, idzawira. Mayambuya ake ndi ochepa, ndipo nyengo yamvula yamvula imatha kuyamwa chinyezi pa keke. Kwa zitsulo zowopsa ndi zitsulo zina, ndizotsika kwambiri, zomwe, makamaka, zimakhala ndi kuchuluka kwambiri kwamkuwa koma palibe kuwonongeka kwa chitsulo. Ammonium chloride can be obtained from the neutralization reaction of ammonia and hydrogen chloride or ammonia and hydrochloric acid (reaction equation: NH3 + HCl → NH4Cl). Atatenthedwa, lidzawola mu hydrogen chloride ndi ammonia zomwe zimachitika (equation: NH4. HCL) ndi zomwe zimapangitsa kuti chidebe chikhale chotseguka.
Amonium chloride amagwiritsidwa ntchito makamaka pa mabatire owuma, mabatire osungira ammonium, zojambula, zojambula, ndi zina. Ndi feteleza wachilengedwe a acidic komanso oyenera tirigu, mpunga, chimanga, ranseed ndi mbewu zina. Imakhala ndi zotsatira zokhala ndi mphamvu yolimba komanso yosinthira mawonekedwe makamaka makamaka mbewu ya thonje komanso lansan. Komabe, chifukwa cha mtundu wa ammonium chloride, ngati ntchito sikolondola, zimabweretsa zovuta zina ndi zokolola.
Mikhalidwe yaukadaulo: Kukhazikitsa kwa Republic of China National Standard GB-2946-82.

Amonium chloride amagwiritsidwa ntchito ngati thickiner komanso ngati owonjezera omwe si odana. Malinga ndi zodzikongoletsera zodzikongoletsera, gawo la ammonium limapereka zokhuza kapena kusiliratu zomwe anthu ena amalumikizana ndi olola kapena kumasuka, ndipo nthawi zambiri amamwa mowa. Kugwiritsa ntchito kwa ammonium chloride ndi chifukwa chokonda.
Amonium chloride ndi mtanda ndi chakudya choyitanira ndi ma kristols opanda utoto kapena ufa woyera. pafupifupi 30-38 g imasungunuka m'madzi pa 25 ° C. PH ya yankho limodzi pa 25 ° C ndi 5.2. Amagwiritsidwa ntchito ngati mtanda wopindika ndi zowonjezera kununkhira mu zinthu zophika komanso ngati gwero la nayitrogeni ku eyala. Amagwiritsidwanso ntchito muzokonda komanso kuleka. Liwu linanso la mchere ndi ammonium chokha.
Makristo oyera opangidwa ndi ammonia mchere akuchita pa hydrochloric acid yotsatiridwa ndi crystallization. Amonium chloride imadziwikanso kuti mafuta ammoniac. Sungunulani m'madzi ndi mowa, ammonium chloride adagwiritsidwa ntchito ngati gawo la mapepala ambiri, kuphatikiza pepala lamchere, pepala la albumen, ndi albumen Emulsion njira.
