Singathanda ukwabelana nawe ngezimvo zethu kwaye samkele izimvo kunye nemibuzo yakho.
ThymolphthaleinIgama lezenzululwazi ngu “3,3-bis(4-hydroxy-5-isopropyl-2-methylphenyl)-phthalide”, into esebenza kwizinto eziphilayo. Ifomula yeekhemikhali yi-C28H30O4, kwaye ubunzima be-molecular yi-430.54. Ingumgubo omhlophe wekristale. Inyibilika ngokulula kwi-ether, i-acetone, i-asidi ye-sulfuric kunye ne-alkaline, kwaye ayinyibiliki emanzini. Ihlala isetyenziswa njengesalathisi se-acid-base, kwaye uluhlu lwayo lokutshintsha umbala we-pH luyi-9.4-10.6, kwaye umbala utshintsha ukusuka kwi-colorless ukuya eluhlaza okwesibhakabhaka. Xa isetyenziswa, isoloko ilungiswa ibe yi-0.1% 90% yesisombululo se-ethanol. Ikwahlala ilungiswa kunye nezinye izikhombisi ukwenza isalathiso esithambileyo esidityanisiweyo ukwenza uluhlu lwalo lokutshintsha umbala lube mxinwa kwaye uqwalaselo lucace ngakumbi.
| INTO | UMGANGATHO | IZIPHUMO |
| Ukuchongwa | Umgubo omhlophe ukuya kumhlophe | Iyahambelana |
| 1H-NMR | I-spectrum efanayo kunye nereferensi | Dlula |
| HPLC ubunyulu | ≥98% | 99.6% |
| Ilahleko ekomisweni | 1% ubuninzi | 0.24% |
I-Thymolphthalein isoloko isetyenziswa njengesalathisi se-acid-base, kunye ne-pH yokutshintsha kombala we-9.4 ukuya kwi-10.6, kunye nokutshintsha kombala ukusuka kwi-colorless ukuya eluhlaza okwesibhakabhaka. Xa isetyenziswa, isoloko ilungiswa njengesisombululo se-ethanol ye-0.1% 90%, kwaye isoloko ixutywa nezinye izikhombisi ukwenza isalathisi esixubileyo ukwenza uluhlu lwalo lokutshintsha umbala lube luncinci kwaye lucace ukuba lugcinwe. Ngokomzekelo, isalathisi esenziwe ngokuxuba isisombululo se-ethanol ye-0.1% ye-reagent kunye ne-0.1% yesisombululo se-ethanol ye-phenolphthalein ayinambala kwisisombululo se-acidic, emfusa kwisisombululo se-alkaline, kwaye yavuka kwi-pH 9.9 (indawo yokutshintsha umbala), ekulula kakhulu ukuyiqwalasela.
