Siyakwamukela ngobuqotho ukuthi uvakashele inkampani yethu noma usishayele ucingo ukuze sizobambisana!
Intuthuko yethu incike emishinini ethuthukisiwe, amakhono amahle kakhulu kanye namandla obuchwepheshe aqiniswa njaloI-Thymolphthalein kanye ne-125-20-2, Imikhiqizo yethu ithunyelwe kakhulu eningizimu-mpumalanga ye-Asia Euro-America, kanye nokuthengiswa kwayo yonke izwe lethu. Futhi kuye ngekhwalithi enhle kakhulu, intengo efanelekile, isevisi engcono kakhulu, sithole impendulo enhle evela kumakhasimende aphesheya kwezilwandle. Wamukelekile ukuthi ujoyine nathi ukuze uthole amathuba nezinzuzo ezengeziwe. Samukela amakhasimende, izinhlangano zebhizinisi kanye nabangani abavela kuzo zonke izingxenye zomhlaba ukuthi basithinte futhi bafune ukubambisana ukuze bathole izinzuzo ezifanayo.
I-ThymolphthaleinIgama lesayensi elithi “3,3-bis(4-hydroxy-5-isopropyl-2-methylphenyl)-phthalide”, okuyi-reagent ephilayo. Ifomula yamakhemikhali yi-C28H30O4, kanti isisindo sama-molecule singama-430.54. Iyimpuphu emhlophe ekristalu. Incibilika kalula ku-ether, i-acetone, i-sulfuric acid kanye nezixazululo ze-alkaline, futhi ayincibiliki emanzini. Ivame ukusetshenziswa njengesibonakaliso se-acid-base, kanti ububanzi bayo bokushintsha kombala be-pH bungu-9.4-10.6, kanti umbala uyashintsha usuka kokungenambala uye koluhlaza okwesibhakabhaka. Uma isetshenziswa, ivame ukulungiswa ibe yisisombululo se-ethanol esingu-0.1% 90%. Ivame futhi ukulungiswa nezinye izinkomba ukuze kwakhiwe isibonakaliso esithambile esihlanganisiwe ukuze kwenziwe ububanzi bayo bokushintsha kombala bube buncane futhi ukubonwa kucace.

I-Thymolphthalein ivame ukusetshenziswa njengesibonakaliso se-acid-base, enobubanzi bokushintsha kombala be-pH obungu-9.4 kuya ku-10.6, kanye nokushintsha kombala kusuka kokungenambala kuya koluhlaza okwesibhakabhaka. Uma isetshenziswa, ivame ukulungiswa njengesixazululo se-ethanol esingu-0.1% 90%, futhi ivame ukuhlanganiswa nezinye izinkomba ukuze kwakhiwe isibonakaliso esixubile ukuze kwenziwe ububanzi bayo bokushintsha kombala bube buncane futhi bucace ukuze bubonwe. Isibonelo, isibonakaliso esenziwe ngokuxuba isixazululo se-ethanol esingu-0.1% salesi sidakamizwa nesisombululo se-ethanol esingu-0.1% se-phenolphthalein asinambala esixazululweni esine-acid, sinsomi esixazululweni se-alkaline, futhi sikhuphuke ku-pH 9.9 (indawo yokushintsha kombala), okulula kakhulu ukuyibona.
