Idizayini edumile ye-Chemical Reagent pH Inkomba 99% Thymolphthalein CAS 125-20-2
Ukuthuthuka kwethu kuncike emishinini ethuthukisiwe, amathalente aphambili namandla obuchwepheshe aqinisa ngokuqhubekayo ku-Popular Design for Chemical Reagent pH Inkomba engu-99%I-Thymolphthalein CAS 125-20-2, Masibambisane ukuze sikhiqize ngokuhlanganyela ikusasa elihle elibonakalayo. Siyakwamukela ngobuqotho ukuthi uvakashele inkampani yethu noma usishayele ukuze sibambisane!
Ukuthuthukiswa kwethu kuncike emishinini ethuthukisiwe, amathalente amahle kakhulu kanye namandla obuchwepheshe aqiniswa ngokuqhubekayoI-Thymolphthalein ne-125-20-2, Imikhiqizo yethu ithunyelwe kakhulu eningizimu-mpumalanga ye-Asia Euro-America, futhi idayiselwa kulo lonke izwe lethu. Futhi kuye ngekhwalithi enhle kakhulu, intengo enengqondo, isevisi engcono kakhulu, sinempendulo enhle evela kumakhasimende aphesheya kwezilwandle. Wamukelekile ukuthi usijoyine ukuze uthole amathuba nezinzuzo ezengeziwe. Samukela amakhasimende, izinhlangano zamabhizinisi nabangane abavela kuzo zonke izingxenye zomhlaba ukuze baxhumane nathi futhi bafune ukubambisana ukuze bathole izinzuzo ezifanayo.
ThymolphthaleinIgama lesayensi yi-“3,3-bis(4-hydroxy-5-isopropyl-2-methylphenyl)-phthalide”, okuyi-organic reagent. Ifomula yamakhemikhali yi-C28H30O4, futhi isisindo samangqamuzana singu-430.54. Impushana emhlophe ecwebezelayo. Incibilika kalula ku-ether, i-acetone, i-sulfuric acid ne-alkaline solutions, futhi ayincibiliki emanzini. Ivamise ukusetshenziswa njengenkomba ye-acid-base, futhi ububanzi bayo bokushintsha umbala we-pH bungu-9.4-10.6, futhi umbala ushintsha usuka ongenambala ube luhlaza okwesibhakabhaka. Uma isetshenziswa, ivame ukulungiswa ibe yisisombululo se-ethanol esingu-0.1% 90%. Ibuye ijwayele ukulungiswa nezinye izinkomba ukwenza inkomba ehlangene emnene ukuze wenze uhla lwayo lokushintsha umbala lube luncane kanye nokubona kucace.

Thymolphthaleinivamise ukusetshenziswa njengenkomba ye-acid-base, enobubanzi bokushintsha umbala we-pH obungu-9.4 ukuya ku-10.6, kanye noshintsho lombala ukusuka kokungenambala ukuya kokuluhlaza okwesibhakabhaka. Uma isetshenziswa, ivame ukulungiswa njengesixazululo se-ethanol esingu-0.1% 90%, futhi ivamise ukuxutshwa nezinye izinkomba ukwenza inkomba exubile ukwenza uhla lwaso lokushintsha umbala lube luncane futhi lucace ukubhekwa. Isibonelo, inkomba eyenziwe ngokuxuba isixazululo se-ethanol esingu-0.1% salesi siphehli nesisombululo se-ethanol esingu-0.1% se-phenolphthalein asinambala kusixazululo esine-asidi, sinsomi esixazululweni se-alkali, futhi saphakama ku-pH 9.9 (iphuzu lokushintsha umbala), okulula kakhulu ukulibona.
