Uphuhliso lwethu luxhomekeke kwizixhobo eziphambili, iitalente ezigqwesileyo kunye nemikhosi yetekhnoloji eyomelezwa ngokuqhubekayoI-Thymolphthalein kunye ne-125-20-2, Iimveliso zethu ziye zathunyelwa ikakhulu kumazantsi-mpuma e-Asia Euro-America, kunye neentengiso kulo lonke ilizwe lethu. Kwaye kuxhomekeke kumgangatho obalaseleyo, ixabiso elifanelekileyo, inkonzo engcono, sinengxelo entle evela kubathengi baphesheya kweelwandle. Wamkelekile ukuba uzibandakanye nathi ngamathuba amaninzi kunye neenzuzo. Samkela abathengi, imibutho yamashishini kunye nabahlobo abavela kuzo zonke iindawo zehlabathi ukuba baqhagamshelane nathi kwaye bafune intsebenziswano ukuze bafumane inzuzo efanayo.
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% |
Thymolphthaleinisetyenziswa rhoqo njengesalathisi se-acid-base, kunye ne-pH yokutshintsha kombala we-9.4 ukuya kwi-10.6, kunye nokutshintsha kombala ukusuka kwi-colorless ukuya kwi-blue. 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.
