Imikhiqizo Emisha Emisha I-Thymolphthalein CAS 125-20-2 yezinkomba ze-Acid-Base
Amathuluzi aqhutshwa kahle, ithimba labadayisi abanekhono, nezinkampani ezithuthukisiwe zangemuva kokuthengisa; Futhi singamalungu omndeni amakhulu ahlangene, wonke umuntu unamathela enhlanganweni uzuza “ukuhlanganisa, ukuzinikela, ukubekezelela” Imikhiqizo Emisha Eshisayo.ThymolphthaleinI-CAS 125-20-2 Yezinkomba Ze-Acid-Base, Ukwandisa kakhulu izinga lesevisi yethu, inkampani yethu ingenisa inombolo enkulu yamadivayisi athuthukile aphesheya kwezilwandle. Siyakwamukela amakhasimende avela ekhaya naphesheya ukuze uxhumane nawo futhi ubuze!
Amathuluzi aqhutshwa kahle, ithimba labadayisi abanekhono, nezinkampani ezithuthukisiwe zangemuva kokuthengisa; Futhi singamalungu omndeni amakhulu obumbene, wonke umuntu unamathela enhlanganweni ahlomule “ukuhlanganiswa, ukuzinikela, ukubekezelelana” , Ngokuhlanganisa ukukhiqiza nemikhakha yezohwebo lwangaphandle, singanikeza izixazululo eziphelele zamakhasimende ngokuqinisekisa ukulethwa kwezinto ezifanele endaweni efanele ngesikhathi esifanele, okusekelwa ulwazi lwethu oluningi, amandla okukhiqiza anamandla, ikhwalithi engaguquki, ukulawulwa kwemikhiqizo ehlukahlukene kanye nephothifoliyo yokuthengisa ngaphambi kwephothifoliyo yethu yokuthengisa. Sithanda ukwabelana ngemibono yethu nawe futhi siyakwamukela ukuphawula kwakho nemibuzo.
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.
| ITEM | IZINGA | RESULT |
| Ukuhlonza | Impushana emhlophe ukuya kokumhlophe | Iyahambisana |
| 1H-NMR | I-spectrum efanayo nereferensi | Dlula |
| Ubumsulwa be-HPLC | ≥98% | 99.6% |
| Ukulahlekelwa ekomisweni | 1%ubuningi | 0.24% |
I-Thymolphthalein ivamise ukusetshenziswa njengenkomba ye-acid-base, enobubanzi bokushintsha umbala we-pH obungu-9.4 ukuya ku-10.6, kanye nokushintsha kombala ukusuka kokungabi mbala 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.
Imikhiqizo ipakishwa esikhwameni, i-25kg/drum
Amathuluzi aqhutshwa kahle, ithimba labadayisi abanekhono, nezinkampani ezithuthukisiwe zangemuva kokuthengisa; Siphinde sibe amalungu omndeni amakhulu ahlangene, wonke umuntu unamathela enhlanganweni ahlomule “ukuhlanganiswa, ukuzinikela, ukubekezelelana” Kwemikhiqizo Emisha Eshisayo I-Thymolphthalein CAS 125-20-2 Yezinkomba Ze-Acid-Base, Ukwandisa kakhulu ikhwalithi yesevisi yethu, inkampani yethu ingenisa inombolo enkulu yamadivayisi athuthukile aphesheya kwezilwandle.

Imikhiqizo Emisha Eshisayo I-Thymolphthalein kanye ne-CAS 125-20-2, Ngokuhlanganisa ukukhiqiza nemikhakha yezohwebo yangaphandle, singanikeza izixazululo eziphelele zamakhasimende ngokuqinisekisa ukulethwa kwezinto ezifanele endaweni efanele ngesikhathi esifanele, okusekelwa ulwazi lwethu oluningi, amandla okukhiqiza anamandla, ikhwalithi engaguquki, iphothifoliyo yemikhiqizo ehlukahlukene kanye nokulawulwa kwenkambiso yokudayiswa kwemboni yethu kanye nokulawulwa kwemboni yethu. Sithanda ukwabelana ngemibono yethu nawe futhi siyakwamukela ukuphawula kwakho nemibuzo.
