Kodi Phenolphthalein cas 77-09-8 ndi chiyani?

Phenolphthalein ndi asidi ofooka a organic, omwe amawoneka ngati oyera kapena achikasu pang'ono makhiristo abwino kutentha kutentha. Ndiwopanda fungo komanso osakoma. Ndizovuta kusungunuka m'madzi koma kusungunuka mosavuta mu mowa (ethanol) ndi ether. Amasungunuka mu njira ya mowa kuti apange chizindikiro cha acid-base. Ndiwopanda mtundu wa acidic solution komanso wofiira mu alkali solution kapena alkali metal carbonate solution. Komabe, ngati ili mumchere wambiri wa alkali, imatulutsa trimetallic acid yopanda mtundu. mchere, mtundu wofiira umatha

Kugwiritsa ntchito

1. Zida zopangira mankhwala kwamakampani opanga mankhwala: oyenera kudzimbidwa mwachizolowezi komanso amakani, omwe amapezeka m'mapiritsi, ma suppositories ndi mitundu ina ya mlingo.

2. Phenolphthalein yogwiritsidwa ntchito mu organic synthesis: makamaka yogwiritsidwa ntchito popanga mapulasitiki, makamaka pakupanga kwa naphthyridine polyaryl ether ketone polyaryl ether ketone ma polima. Mtundu uwu wa polima umalimbana kwambiri ndi kutentha, kukana madzi, komanso kukana mankhwala. Chifukwa cha kukana kwa dzimbiri, kukana kukalamba kwa kutentha komanso kukonza bwino ndi mawonekedwe ake, ulusi, zokutira ndi zida zophatikizika zopangidwa kuchokera pamenepo posachedwapa zimagwiritsidwa ntchito kwambiri pazida zamagetsi, zida zamakina, zoyendera, zakuthambo, uinjiniya wamagetsi a atomiki ndi magulu ankhondo.

3. Phenolphthalein amagwiritsidwa ntchito ngati chizindikiro cha acid-base, chizindikiro cha titration ya njira zopanda madzi, ndi reagent yowunikira chromatographic.
