Chii chinonzi Thymolphthalein CAS 125-20-2?

Zita resainzi reThymolphthalein nderekuti "3,3-bis(4-hydroxy-5-isopropyl-2-methylphenyl)-phthalide", inova reagent yeorganic. Fomura yemakemikari iyi iC28H30O4, uye huremu hwemorekuru i430.54. Iupfu hwe crystalline chena. Inonyungudika nyore nyore mu ether, acetone, sulfuric acid uye alkaline solutions, uye hainyungudike mumvura. Inowanzoshandiswa sechiratidzo che acid-base, uye pH yayo yekuchinja kwemavara i9.4-10.6, uye ruvara runoshanduka kubva pakusachena kuenda kubhuruu. Kana ikashandiswa, inowanzo gadzirwa kuita 0.1% 90% ethanol solution. Inowanzo gadzirwawo nezvimwe zviratidzo kuti igadzire chiratidzo chakabatana zvinyoro nyoro kuti chiite kuti shanduko yemavara iite diki uye kucherechedzwa kwacho kuve pachena.

Kushandiswa

Thymolphthalein inowanzo shandiswa sechiratidzo cheacid-base, ine pH yekuchinja kweruvara kubva pa9.4 kusvika 10.6, uye shanduko yeruvara kubva pakusava neruvara kuenda kubhuruu. Kana ikashandiswa, inowanzo gadzirwa se 0.1% 90% ethanol solution, uye inowanzo sanganiswa nezvimwe zviratidzo kuti igadzire chiratidzo chakasanganiswa kuti chiite kuti shanduko yeruvara rwayo ive diki uye yakajeka kuti ionekwe. Semuenzaniso, chiratidzo chinogadzirwa nekusanganisa mhinduro ye0.1% ethanol ye reagent iyi ne 0.1% ethanol solution ye phenolphthalein haina ruvara mu acidic solution, yepepuru mu alkaline solution, uye yakasimuka pa pH 9.9 (nzvimbo yekuchinja kweruvara), izvo zviri nyore kuona.
