    Waa maxay Thymolfthalein CAS 125-20-2?

    Magaca sayniska ee Thymolphthalein waa "3,3-bis(4-hydroxy-5-isopropyl-2-methylphenyl) -phthalide", kaas oo ah reagent organic. Qaabka kiimikada waa C28H30O4, miisaankuna waa 430.54. Waa budo crystalline cad. Waxay si fudud ugu milmi kartaa ether, acetone, sulfuric acid iyo xalalka alkaline, oo aan lagu milmi karin biyaha. Inta badan waxaa loo adeegsadaa tilmaame-saldhig-acid, iyo cabbirka isbeddelka midabka pH waa 9.4-10.6, midabkuna wuu isbeddelaa mid aan midab lahayn oo buluug ah. Marka la isticmaalo, waxaa badanaa loo diyaariyaa 0.1% 90% ethanol xal. Waxa kale oo inta badan lagu diyaariyaa tilmaamayaasha kale si ay u sameeyaan tilmaame isku dhafan oo jilicsan si ay u sameeyaan isbeddelka midabkiisa mid cidhiidhi ah iyo indho-indheyntu mid cad.

    Codsiga

    Thymolphthalein waxaa badanaa loo isticmaalaa tilmaame-saldhig acid, oo leh pH midabka isbeddelka kala duwan ee 9.4 ilaa 10.6, iyo isbeddelka midab aan midab lahayn oo buluug ah. Marka la isticmaalo, waxaa badanaa loo diyaariyaa 0.1% 90% ethanol, waxaana badanaa lagu qasaa tilmaamayaasha kale si loo sameeyo tilmaame isku dhafan si loo sameeyo isbeddelka midabkiisa mid cidhiidhi ah oo cad in la ilaaliyo. Tusaale ahaan, tilmaame lagu sameeyay isku dhafka 0.1% ethanol ee reagent iyo 0.1% ethanol ee phenolphthalein waa mid aan midab lahayn xal acidic ah, guduudan ee xalalka alkaline, oo kor u kacay pH 9.9 (midabka isbeddelka), taas oo ah aad u fudud in la ilaaliyo.
