Kodi Phenolphthalein CAS 77-09-8 ndi chiyani?

Phenolphthalein ndi asidi wofooka wa organic, womwe umawoneka ngati makhiristo oyera kapena achikasu pang'ono kutentha kwa chipinda. Phenolphthalein 77-09-8 ndi yopanda fungo komanso kukoma. Phenolphthalein 77-09-8 ndi yovuta kusungunuka m'madzi koma imasungunuka mosavuta mu mowa (ethanol) ndi ether. Phenolphthalein imasungunuka mu yankho la mowa kuti ipange chizindikiro cha acid-base. Phenolphthalein 77-09-8 ndi yopanda mtundu mu yankho la acidic ndipo ndi yofiira mu yankho la alkali kapena yankho la alkali metal carbonate. Komabe, ngati ili mu yankho la alkali lokhazikika, imapanga trimetallic acid yopanda mtundu. Mchere, mtundu wofiira umatha

Kugwiritsa ntchito

1. Zipangizo zopangira mankhwala zogwiritsidwa ntchito m'makampani opanga mankhwala: zoyenera kudzimbidwa kosalekeza komanso kosalekeza, zomwe zimapezeka m'mapiritsi, m'mapiritsi ndi m'njira zina zoyezera.

2. Phenolphthalein yomwe imagwiritsidwa ntchito popanga zinthu zachilengedwe: ufa wa phenolphthalein womwe umagwiritsidwa ntchito makamaka popanga mapulasitiki opangidwa, makamaka popanga ma polima a naphthyridine polyaryl ether ketone polyaryl ether ketone. Mtundu uwu wa polima uli ndi kukana kutentha bwino, kukana madzi, komanso kukana mankhwala. Chifukwa cha kukana dzimbiri, kukana kutentha komanso kukonza bwino komanso kupanga bwino, ulusi, zokutira ndi zinthu zopangidwa kuchokera pamenepo zimagwiritsidwa ntchito kwambiri posachedwa mu zida zamagetsi, zida zamakanika, mayendedwe.

3. Phenolphthalein yogwiritsidwa ntchito ngati chizindikiro cha acid-base, chizindikiro cha titration ya mayankho osakhala amadzi, komanso reagent yowunikira chromatographic.
