Uphuhliso lwethu luxhomekeke kwizixhobo eziphambili, iziphiwo ezigqwesileyo kunye namandla etekhnoloji aqinisiweyo rhoqoI-Thymolphthalein kunye ne-125-20-2, Iimveliso zethu zithunyelwe kumazwe angaphandle kakhulu kumzantsi-mpuma we-Asia Euro-America, kwaye zithengiswa kulo lonke ilizwe lethu. Kwaye ngokuxhomekeke kumgangatho ogqwesileyo, ixabiso elifanelekileyo, inkonzo engcono, sifumene impendulo entle evela kubathengi baphesheya. Wamkelekile ukuba ujoyine nathi ukuze ufumane amathuba kunye neenzuzo ezingaphezulu. Siyamkela abathengi, imibutho yoshishino kunye nabahlobo abavela kuzo zonke iindawo zehlabathi ukuba banxibelelane nathi kwaye bafune intsebenziswano ukuze bafumane iingenelo ezifanayo.
I-ThymolphthaleinIgama lesayensi le-“3,3-bis(4-hydroxy-5-isopropyl-2-methylphenyl)-phthalide”, eyi-reagent yendalo. Ifomyula yekhemikhali yi-C28H30O4, kwaye ubunzima be-molecular yi-430.54. Yipowder emhlophe ekristale. Inyibilika lula kwi-ether, i-acetone, i-sulfuric acid kunye nezisombululo ze-alkaline, kwaye ayinyibiliki emanzini. Ihlala isetyenziswa njengesalathisi se-acid-base, kwaye uluhlu lwayo lotshintsho lombala lwe-pH yi-9.4-10.6, kwaye umbala uyatshintsha ukusuka kokungenambala ukuya koluhlaza okwesibhakabhaka. Xa isetyenziswa, idla ngokulungiswa ibe yisisombululo se-ethanol esingu-0.1% 90%. Ikwalungiswa nezinye izalathisi ukwenza isalathisi esidibeneyo esithambileyo ukwenza uluhlu lwayo lotshintsho lombala lube mxinwa kwaye ukubonwa kucace ngakumbi.

I-Thymolphthalein idla ngokusetyenziswa njengesalathisi se-asidi, enoluhlu lotshintsho lombala lwe-pH oluyi-9.4 ukuya kwi-10.6, kunye notshintsho lombala ukusuka kokungenambala ukuya koluhlaza okwesibhakabhaka. Xa isetyenziswa, idla ngokulungiswa njengesisombululo se-ethanol esingu-0.1% 90%, kwaye idla ngokuxutywa nezinye izibonakaliso ukwenza isalathisi esixutyiweyo ukwenza uluhlu lwayo lotshintsho lombala lube mxinwa kwaye lucace ngakumbi ukuba lubonwe. Umzekelo, isalathisi esenziwe ngokuxuba isisombululo se-ethanol esingu-0.1% sale reagent kunye nesisombululo se-ethanol esingu-0.1% se-phenolphthalein asinambala kwisisombululo se-asidi, simfusa kwisisombululo se-alkaline, kwaye sinyuka kwi-pH 9.9 (indawo yokutshintsha kombala), okulula kakhulu ukuyibona.
