2,2′,5,5′-Tetrachlorobenzidine CAS:15721-02-5

I-2,2', 5,5'-Tetrachlorobenzidine isetshenziswa kakhulu njenge-intermediate yedayi yezimboni, ikakhulukazi ekwakhiweni kwamadayi e-azo. Lezi zinhlobo zamadayi zisetshenziswa kakhulu ezindwangu, ephepheni, nasepulasitikini ngenxa yemibala yazo egqamile kanye nezakhiwo zayo zokushesha ezinhle kakhulu. I-TCB ingasebenza njenge-ejenti yokuhlanganisa ekwakhiweni kwamakhemikhali ahlukahlukene edayi, ayingxenye yezinqubo zokufaka imibala embonini yezindwangu. Ngaphezu kwendima yayo ekukhiqizeni udayi, i-TCB isetshenziswa nasekukhiqizweni kwama-pigment kanye nokumbozwa. Ukufakwa esikhundleni kwe-chlorine kwenhlanganisela kuthuthukisa ukuzinza kwayo kanye nezakhiwo zombala, okwenza ifaneleke ukusetshenziswa lapho kudingeka khona ubuqotho bombala obuqinile, njengasekuqedweni kwezimoto kanye nokumbozwa kwezimboni. Ngaphezu kwalokho, i-TCB iye yacwaningwa ngokusetshenziswa kwayo okungenzeka ekusetshenzisweni kwe-electrochemical, isebenza njengesandulela sokwenza ama-polymer nezinto zokwakha. Isakhiwo sayo esiyingqayizivele sama-molecule sivumela ukuguqulwa okungathuthukisa izakhiwo zala ma-polymer, okwenza afaneleke kumadivayisi kagesi. Naphezu kokusebenza kwayo, kubalulekile ukubhekana nokuphathwa kwe-2,2', 5,5'-Tetrachlorobenzidine ngokuqapha, njengoba ihlukaniswe njengento eyingozi. Ukuchayeka ku-TCB kungadala izingozi zempilo, okuhlanganisa nemiphumela ebangela umdlavuza, okudinga izinyathelo eziqinile zokulawula kanye nezinqubo zokuphepha ekusetshenzisweni kwayo kwezimboni. Umthelela wemvelo we-TCB kanye nemikhiqizo yayo yokuwohloka nawo udinga ukucatshangelwa ngokucophelela, okukhuthaza isidingo sezinye izindlela eziphephile kanye nemikhuba yokuphathwa kwemfucuza ethuthukisiwe ezimbonini ezisebenzisa le nhlanganisela.
