Iyini i-Phenolphthalein cas 77-09-8?

I-Phenolphthalein iyi-asidi ephilayo ebuthakathaka, ebonakala njengamakristalu amhlophe noma aphuzi kancane ekamelweni lokushisa.Ayinaphunga futhi ayinambitheki.Kunzima ukuncibilika emanzini kodwa kuncibilika kalula otshwaleni (i-ethanol) ne-ether.Incibilika kusisombululo sotshwala ukwenza inkomba ye-acid-base.Ayinambala kusixazululo esine-asidi futhi ibomvu kusixazululo se-alkali noma isixazululo se-alkali sensimbi ye-carbonate.Kodwa-ke, uma isesisombululo se-alkali esigxilile, izokhiqiza i-trimetallic acid engenambala.usawoti, umbala obomvu uyafiphala

Isicelo

1. Izinto zokusetshenziswa kwemithi embonini eyenza imithi: zilungele ukuqunjelwa okuvamile kanye nenkani, ezitholakala kumaphilisi, ama-suppositories namanye amafomu omthamo.

2. I-Phenolphthalein esetshenziswe ku-organic synthesis: ikakhulukazi esetshenziselwa amapulasitiki okwenziwa, ikakhulukazi ukuhlanganiswa kwe-naphthyridine polyaryl ether ketone polyaryl ether ketone polymers.Lolu hlobo lwe-polymer lunokumelana okuhle kakhulu nokushisa, ukumelana namanzi, nokumelana namakhemikhali.Ngenxa yokumelana nokugqwala, ukumelana nokuguga kokushisa kanye nokucutshungulwa okuhle nokubukeka kahle, imicu, ukumbozwa kanye nezinto eziyinhlanganisela ezenziwe kuyo maduzane zisetshenziswa kabanzi ezintweni zikagesi, imishini yemishini, ezokuthutha, i-aerospace, ubunjiniyela bamandla e-athomu kanye nezinkundla zempi.

3. I-Phenolphthalein esetshenziswa njengenkomba ye-acid-base, inkomba ye-titration yezixazululo ezingezona amanzi, kanye ne-reagent yokuhlaziya i-chromatographic.
