I-Phenothiazine, isakhi esisebenzayo esisebenza ngezindlela eziningi esinefomula yamangqamuzana i-C12H9NS, idonsele ukunakwa ngokusetshenziswa kwayo okubanzi kuzo zonke izimboni ezihlukahlukene.Kusukela kwezemithi kuya emikhiqizweni yezolimo, izakhiwo zayo ezihlukile ziyenza ibaluleke kakhulu ezinqubweni eziningi.
Etholwe ekuqaleni njengempushana ephuzi ukuya kokuluhlaza ngokumpunga noma icrystalline, ukunyibilika kwe-phenothiazine ku-benzene, ether, ne-acetic acid eshisayo, kanye nokungancibiliki kwayo emanzini ne-petroleum ether, kwavusa isithakazelo sabacwaningi.Ikhono layo lokuvimbela ama-vinyl monomers lavula indlela yokusetshenziswa kwayo kabanzi ekukhiqizeni i-acrylic acid, i-acrylic esters, i-methyl methacrylate, ne-vinyl acetate.Lolu hlelo lokusebenza alugcinanga ngokulula izinqubo zokukhiqiza kodwa futhi luthuthukise ikhwalithi yomkhiqizo.
Ngaphandle kwendima yayo ekukhiqizeni i-polymer, i-phenothiazine idlala indima ebalulekile ekuhlanganiseni kwemithi.Ukuzibandakanya kwayo ekukhiqizeni ama-antihistamine, ama-tranquilizers, neminye imithi kugcizelela ukubaluleka kwayo emkhakheni wezempilo.Ukwengeza, i-phenothiazine ithola usizo ekuhlanganiseni odayi, ama-antioxidants, nama-polyethers, iphinde igqamise ukuguquguquka kwayo embonini yamakhemikhali.
Kwezolimo, i-phenothiazine isebenza njengengxenye ebalulekile emakhazeni ezilwane kanye nezibulala-zinambuzane zezihlahla zezithelo.Ukuphumelela kwayo ekulweni nezinambuzane nezinambuzane ezinhlobonhlobo kugcizelela ukubaluleka kwayo ekuqinisekiseni impilo yemfuyo kanye nokuvikelwa kwezitshalo.Kodwa-ke, ubuthi bayo obungaba khona kanye nomthelela emvelweni kudinga ukusetshenziswa ngendlela efanele kanye nokuhambisana nemithetho yezokuphepha.
Naphezu kokusetshenziswa kwayo okuphawulekayo, i-phenothiazine ayinazo izinselele.Ukugcina isikhathi eside kuholela ekubeni umbala ube mnyama kanye nokuba sengozini kwe-oxidation, okugcizelela isidingo sokuphatha kahle kanye nezivumelwano zokugcina.Ngaphezu kwalokho, izici zayo ze-sublimation kanye nokucasuka kwesikhumba okungaba khona kugqamisa ukubaluleka kwezinyathelo zokuphepha ekuyiphatheni nasekukhiqizeni kwayo.
Sengiphetha, izici eziningi ze-phenothiazine ziyenza ibe yimpahla ebalulekile kuzo zonke izimboni.Kusukela ekuthuthukiseni ukusebenza kwezidakamizwa kuya ekuvikeleni isivuno sezolimo, iminikelo yayo ayinakuphikwa.Njengoba ucwaningo luqhubeka nokuvumbulula izinhlelo zokusebenza ezintsha kanye nokwenza ngcono izinqubo ezikhona, indima ye-phenothiazine ekubumbeni imikhakha ehlukahlukene yomnotho kulindeleke ukuthi iqhubeke.
