Phenothiazine: Kuphatikiza Kosiyanasiyana Ndi Ntchito Zosiyanasiyana

Phenothiazine, organic compound yokhala ndi mamolekyu a C12H9NS, yakopa chidwi chifukwa cha ntchito zake zosiyanasiyana m'mafakitale osiyanasiyana.Kuchokera pazamankhwala kupita kuzinthu zaulimi, mawonekedwe ake apadera amapangitsa kuti ikhale yofunikira m'njira zambiri.

Poyambirira anapeza ngati ufa wachikasu mpaka wobiriwira kapena crystalline, kusungunuka kwa phenothiazine mu benzene, ether, ndi hot acetic acid, komanso kusasungunuka kwake m'madzi ndi petroleum ether, kudachititsa chidwi ofufuza.Kutha kwake kuletsa ma vinyl monomers kunatsegula njira yogwiritsidwa ntchito kwambiri popanga acrylic acid, acrylic esters, methyl methacrylate, ndi vinyl acetate.Pulogalamuyi yangosintha njira zopangira zinthu komanso zakulitsa mtundu wazinthu.

Kupitilira gawo lake pakupanga ma polima, phenothiazine imagwiranso ntchito yofunika kwambiri pakupanga mankhwala.Kuchitapo kanthu popanga antihistamines, tranquilizers, ndi mankhwala ena kumatsimikizira kufunika kwake m'gulu lachipatala.Kuphatikiza apo, phenothiazine imapeza zothandiza pakuphatikizika kwa utoto, ma antioxidants, ndi ma polyethers, ndikuwunikiranso kusinthasintha kwake mumakampani opanga mankhwala.

Muulimi, phenothiazine amagwira ntchito ngati gawo lofunikira kwambiri pazamankhwala ophera tizilombo toyambitsa matenda ndi tizirombo tamitengo yazipatso.Kuthandiza kwake polimbana ndi tizilombo tosiyanasiyana komanso tizilombo tosiyanasiyana kumatsindika kufunika kwake poonetsetsa kuti ziweto zili ndi thanzi komanso chitetezo cha mbewu.Komabe, kawopsedwe kake komanso kukhudzidwa kwachilengedwe kumapangitsa kuti azigwiritsa ntchito moyenera komanso kutsatira malamulo achitetezo.

Ngakhale kuti ndi othandiza kwambiri, phenothiazine ilibe zovuta.Kusungirako nthawi yayitali kumapangitsa kuti mtundu ukhale mdima komanso kutengeka ndi okosijeni, kugogomezera kufunikira kosamalira bwino ndi kusunga ma protocol.Kuphatikiza apo, mawonekedwe ake a sublimation komanso kupsa mtima komwe kungachitike pakhungu kumawonetsa kufunikira kwachitetezo chachitetezo pamachitidwe ake ndi kupanga.

Pomaliza, zinthu zambiri za phenothiazine zimapangitsa kuti ikhale yamtengo wapatali m'mafakitale.Kuchokera pakulimbikitsa mphamvu ya mankhwala mpaka kuteteza zokolola zaulimi, zopereka zake nzosatsutsika.Pamene kafukufuku akupitiriza kuwonetsa ntchito zatsopano ndikukonzanso njira zomwe zilipo kale, ntchito ya phenothiazine pakupanga magawo osiyanasiyana a zachuma ikuyenera kupirira.
