Ammonium acetate. Ukulungiswa elebhu kunye nendlela mveliso. isicelo

Le imichiza compound NH4C2H3O2 ukubunjwa eyaziwa kwizangqa njengoba ammonium acetate. Abonakala ngayo kuyinto material crystalline ngaphaya okanye ezimhlophe. Product lokulungiselela bayo acetic acid. Ammonium acetate iveliswa ngokuhlanganisa acid kunye ammonia. Njengoko izinto zifumaneka lula kwaye efikeleleka kakhulu, le ezimbaxa elisetyenziswa additive ukutya (E264) okanye ukubola.
Phakathi iipropati emzimbeni umi hygroscopic. Ukuba anazo ammonium acetate. Amalungiselelo osisiqu phantsi kweemeko elebhu kungenzeka ngeendlela ezininzi. Le yokusabela kwenziwa kanzulu (glacial) acetic acid kunye carbonate Ammonium (ammonium carbonate). Isiphumo basabela njani na ammonium acetate, ukutshabalala asidi, oko ixesha elifutshane iguqulelwa carbon dioxide namanzi.
Indlela abasabela ilandelayo ibandakanya enzonzobila 80% acetic acid ku-10% ammonia (ammonia). Ukuze indlela kufuna lobushushu eliphantsi. Uvikivwa kwisikhongozeli ngumkhenkce lelabhastile kunye reactants, behlunguzela ngamathuba athile oko ngamandla. Ngumphunga le filtrate, ammonium acetate.
Ukuze yokusabela wesithathu usebenzisa zilahlwe acetic acid okanye acetonitrile. Itshiswa ngamanzi. Phakathi iindlela zokuvelisa yesicelo zoshishino bafumana awasabela ngayo xa ammonium acetate olulungiswe acetic acid ukusabela kunye nesisombululo ammonia zolwelo.

Phakathi iindlela zemveliso ye ammonium acetate indlela zibe zodwa, apho umchiza ibangelwa imveliso kwi nemithi iikhemikhali - ammonia. Kodwa njongo iphambili yale yokusabela - diacylated kwincindi.
Into ephawulekayo ammonium acetate kukuba layo ukuba ukubola kubushushu ka-112 ° C kwi acetamide kunye namanzi. Le yokusabela kudla ezicatshuliweyo umzekelo yokubola lweTyuwa kumaqondo obushushu aphantsi kakhulu nje.
Ammonium acetate esetyenziswa kwishishini kunye neemeko elebhu njengoko ulwelo icandelo anti-icing. Ishishini ukutya kuye kwafunyanwa kuyo ukubola olusebenzayo. Ithi isetyenziswe njenge reagent ngexesha ezinye iintlobo organic yokuqaphela. Umsebenzi wophando Laboratory ukuqwalasela usebenziso ammonium acetate njengecandelo izisombululo buffer neprotheyini isimemezelo.
Le nobuchwepheshe kushicilelwa amalaphu okanye ukupeyinta usebenzisa ammonium acetate. Oku kusetyenziswa ekwenziweni ntsholongwane kunye nezinye iimveliso kwishishini loxubo-mayeza. Kwakhona, lisetyenziswa kwi kwimveliso amagwebu irabha, iiplastiki, IVinyl.
Ukusetyenziswa ammonium acetate iinjongo zoshishino kufuna uthutho kunye nokugcinwa imithamo emikhulu. Ngokuqhelekileyo, le umgubo crystalline into zipakishwe ngendlela ekhethekileyo ezingxoweni womluki okanye iibhokisi iphepha. Kuba yokugcina kusetyenziswa kwigumbi owomileyo apho izinto zikwimeko etywiniweyo kwikhava wazo. Le nto ayibubo ziyityhefu kwaye angezanga ubungozi kwimpilo abasebenzi. Amanyathelo xa uphethe le ezimbaxa kubonisa ukukhusela ulusu kunye namehlo.
Ukuba into ziye kumphezulu mucosal wokuqala nge na ngamanzi amaninzi ngamanzi acocekileyo. Emva ukusebenza acetate ammmoniem kufuneka ndakuhlambulula ngesepha namanzi.
Umlilo malunga umchiza uchaphazelekayo ayenzakalisi. Asinto neziqhushumbisi kananjalo akukho ngokukhawuleza. kushishino chemical zasekhaya apha naphaya ukukhululwa kwezinto ngokwaneleyo ukuhlangabezana neemfuno imveliso. Ngaphezu koko, izinto ze ammonium acetate evela kwamanye amazwe. Ngokwemveli, ongenisa ezingundoqo apha China.
