Kukula kwathu kumadalira zida zotsogola, talente yabwino kwambiri komanso mphamvu zamaukadaulo zolimbikitsira mosalekezaThymolphthalein ndi 125-20-2, Zogulitsa zathu zimatumizidwa kumwera chakum'mawa kwa Asia Euro-America, ndikugulitsa kudziko lathu lonse. Ndipo kutengera zabwino kwambiri, mtengo wololera, ntchito yabwino kwambiri, tili ndi mayankho abwino kuchokera kwamakasitomala akunja. Mwalandiridwa kuti mubwere nafe kuti mupeze zambiri komanso zopindulitsa. Tikulandira makasitomala, mabungwe amalonda ndi abwenzi ochokera kumadera onse adziko lapansi kuti atilumikizane ndikupempha mgwirizano kuti tipindule.
ThymolphthaleinDzina la sayansi ndi “3,3-bis(4-hydroxy-5-isopropyl-2-methylphenyl)-phthalide”, yomwe ndi organic reagent. Njira yamankhwala ndi C28H30O4, ndipo kulemera kwa maselo ndi 430.54. Ndi ufa wa crystalline woyera. Amasungunuka mosavuta mu ether, acetone, sulfuric acid ndi alkaline solutions, komanso osasungunuka m'madzi. Nthawi zambiri amagwiritsidwa ntchito ngati chizindikiro cha acid-base, ndipo kusintha kwa mtundu wa pH ndi 9.4-10.6, ndipo mtundu umasintha kuchoka ku mtundu wopanda utoto kupita ku buluu. Akagwiritsidwa ntchito, nthawi zambiri amakonzedwa kukhala 0.1% 90% ethanol solution. Amakonzedwanso nthawi zambiri ndi zizindikiro zina kuti apange chizindikiro chophatikizana chofatsa kuti chipangitse kusintha kwake kwamtundu kukhala kocheperako komanso kuwonetsetsa bwino.

ThymolphthaleinNthawi zambiri amagwiritsidwa ntchito ngati chizindikiro cha acid-base, chokhala ndi pH yosintha mtundu wa 9.4 mpaka 10.6, komanso kusintha kwamtundu kuchokera kumtundu wopanda utoto kupita ku buluu. Akagwiritsidwa ntchito, nthawi zambiri amakonzedwa ngati njira ya 0,1% 90% ya ethanol, ndipo nthawi zambiri amasakanizidwa ndi zizindikiro zina kuti apange chizindikiro chosakanikirana kuti mtundu wake usinthe mtundu ukhale wocheperako komanso womveka bwino kuti uwone. Mwachitsanzo, chizindikiro chopangidwa ndi kusakaniza 0,1% Mowa njira ya reagent ndi 0,1% Mowa njira ya phenolphthalein ndi colorless mu njira acidic, wofiirira mu njira zamchere, ndipo ananyamuka pa pH 9.9 (mtundu kusintha mfundo), amene n'zosavuta kuona.
