Uhlalutyo lwendawo yokubila ye-acetic acid: Iqondo lobushushu, izinto eziphembelelayo kunye nezicelo
I-acetic acid (ifomula yekhemicamikhi ye-Chemical ch₃cooh, ekwabizwa ngokuba yi-acetic acid, i-acid yelungu elisetyenziswa ngokubanzi kwikhemikhali, ukutya kunye namashishini amayeza. Ipropathi yomzimba ye-acetic acid, ingakumbi inqaku layo lokubiliza, libalulekile kwimveliso yemveliso kunye nezicelo kwishishini lekhemikhali. Kweli nqaku, siya kuhlalutya indawo yokubila i-acetic acid, xoxa ngezinto ezinefuthe kunye nokubaluleka kwayo kwiimeko ezahlukeneyo zesicelo.
Isishwankathelo esisisiseko sendawo yokubila ye-acetic acid
Indawo yokubila ye-acetic acid yi-117.9 ° C (i-244.2 f), elinganiswe kwi-themospheric the pumeric the the themospic (1), 101.3 kpa). Kula maqondo obushushu, utshintsho lwe-accetic acid ukusuka kulwelo kwigesi, inkqubo ebaluleke kakhulu kwiinkqubo zekhemikhali. I-Acetic Acid inendawo ebilayo enobubi obuphezulu xa kuthelekiswa nezinye izinto eziqhelekileyo eziphilayo, ezithethwayo ubukhulu becala bubukho beembophelelo ze-hydrogen phakathi kweemolekyuli zayo.
Izinto ezichaphazela indawo yokubila ye-acetic acid
Nangona eyona ndawo yokubila esemgangathweni ye-acetic acid yi-117.9 ° C, ekusebenzeni kobushushu kuyachaphazeleka ngezinto ezininzi. Ingcinezelo inefuthe elibonakalayo kwindawo yokubila. Kumanyano asezantsi (umz. Iimeko ze-vacuum), indawo yokubila ye-acetic acid inciphisa kakhulu, ngelixa imeko yoxinzelelo oluphezulu, inqaku layo lokubila liyanda. Ke ngoko, ngexesha lokuhluka kwezomveliso, elawula uxinzelelo lwenkqubo kunokulawula ngokufanelekileyo ukusebenza ngempumelelo kunye nokwahlulahlula i-acetic acid.
Ukungcola kwisisombululo kunokuba nefuthe kwindawo yokubila ye-acetic acid. Ingakumbi xa i-acetic acid ichaza ezinye izivumelwano, inqaku layo lokubila linokuphambuka kwimilinganiselo emiselweyo. Umzekelo, kwizisombululo ezinamandla, indawo yokubila ye-acetic acid inokuncitshiswa ngenxa ye-azeotrapic phenomena. Ukuqonda nokulawula ezi zinto kubalulekile ukuze uqiniseke iinkqubo zokuvelisa iikhemikhali.
Izicelo ze-Acetic Acid Acing Acing kwishishini
Indawo yokubila ye-acetic acid ayisiyo kuphela iparameter ebaluleke kakhulu kwipropathi yayo, kubalulekile ukuba ichaphazele isicelo sayo kwiinkqubo ezahlukeneyo zemveliso. Isicelo esiqhelekileyo sisidanga kunye nokucocwa kwe-acetic acid. Kwimveliso yemichiza, ulawulo oluchanekileyo lwendawo yokubila linyathelo eliphambili ekufumaneni i-aceid ye-acetic ephezulu. Kwimveliso ye-acetate kunye ne-Acetate Esters, ummiselo wendawo yokubila ye-acetic acid inefuthe ngqo kumgangatho wemveliso kunye nemveliso.
Indawo yokubila ye-acetic acid ikwanazo nezicelo ezibalulekileyo kwiinkqubo zokuhlola okusingqongileyo kunye neenkqubo zonyango. Unyango lwamanzi amdaka okanye igesi yenkunkuma ene-acetic acid inokufezekiswa ngokufumana i-acetic acid ngemfuyo. Ke ngoko, ukucebisa indawo yokubila ye-acetic acid kunye nomthetho wayo oguqukayo kubalulekile ukuba uyilo lwenkqubo efanelekileyo yonyango.
Isishwankathelo
Indawo yokubila ye-acetic acid yiparamitha ebalulekileyo enexabiso lezicelo kwicandelo lekhemikhali. Ukuqonda kunye nokusebenzisana kwezinto eziphembelela kwindawo yokubila ye-acetic acid, enjengoxinzelelo, kunokunceda iinjineli kunye neengcali zenkqubo yokwandisa inkqubo yemveliso kwaye iphucule umgangatho wemveliso. Izicelo ezininzi zendawo yokubila ye-acetic acid ikwabalaselisa ukubaluleka kwayo kwimveliso nokukhusela isisingqongileyo. Kwixesha elizayo lophando kunye nezicelo, uhlalutyo olunzulu lwendawo yokubila ye-acetic acid iya kuqhubeka nokuzisa iiteknoloji zobuqhetseba kwishishini lekhemikhali.
