Thymolphthalein CAS 125-20-2 ni iki?

Izina rya siyansi rya Thymolphthalein ni "3,3-bis (4-hydroxy-5-isopropyl-2-methylphenyl)-phthalide", ikaba ari reagent y’umwimerere. Formula y’ibinyabutabire ni C28H30O4, kandi uburemere bwa molekile ni 430.54. Ni ifu y’umweru ikoze mu cyuma. Irashongesha byoroshye mu eteri, acetone, aside sulfurique na alkaline, kandi ntishongesha mu mazi. Ikunze gukoreshwa nk'ikimenyetso cy’aside-base, kandi pH yayo ihinduka ni 9.4-10.6, kandi ibara rihinduka kuva ku ibara ridafite ibara rijya ku bururu. Iyo ikoreshejwe, akenshi itegurwa mu gisubizo cya ethanol cya 0.1% 90%. Ikunze kandi gutegurwa hamwe n’ibindi bimenyetso kugira ngo hakorwe ikimenyetso cyoroshye gihujwe kugira ngo ibara ryayo rihinduke ribe rito kandi ireberwe neza.

Porogaramu

Thymolphthalein ikunze gukoreshwa nk'ikimenyetso cy'aside-base, ifite pH ihinduka hagati ya 9.4 na 10.6, n'ihinduka ry'ibara riva ku ibara ridafite ibara rijya ku bururu. Iyo ikoreshejwe, ikunze gutegurwa nk'ikimenyetso cya ethanol cya 0.1% 90%, kandi ikunze kuvangwa n'ibindi bimenyetso kugira ngo habeho ikimenyetso kivanze kugira ngo ihinduka ry'ibara ribe rito kandi risobanuke neza. Urugero, ikimenyetso cyakozwe mu kuvanga iki kimenyetso cya ethanol cya 0.1% cy'iki kimenyetso n'ikimenyetso cya ethanol cya 0.1% cya phenolphthalein nta ibara kiri mu kimenyetso cya aside, umuhengeri uri mu kimenyetso cya alkaline, kandi cyazamutse kuri pH 9.9 (aho ibara rihinduka), byoroshye cyane kubibona.
