Iyini iPhenolphthalein CAS 77-09-8?

I-Phenolphthalein iyi-asidi ebuthakathaka e-organic, ebonakala njengamakristalu amhlophe noma aphuzi kancane ekushiseni kwegumbi. I-Phenolphthalein 77-09-8 ayinaphunga futhi ayinambitheki. I-Phenolphthalein 77-09-8 kunzima ukuyincibilikisa emanzini kodwa incibilika kalula ku-alcohol (ethanol) kanye ne-ether. I-Phenolphthalein incibilika kusisombululo sotshwala ukuze yenze inkomba ye-acid-base. I-Phenolphthalein 77-09-8 ayinambala kusisombululo se-acid futhi ibomvu kusisombululo se-alkali noma isixazululo se-alkali metal carbonate. Kodwa-ke, uma ikwisisombululo se-alkali esigxilile, izokhiqiza i-trimetallic acid engenambala. Usawoti, umbala obomvu uyaphela

Isicelo

1. Izinto zokusetshenziswa kwemithi embonini yemithi: ezifanelekela ukuqunjelwa okuvamile nokuphikelelayo, ezitholakala kumaphilisi, ama-suppositories kanye nezinye izindlela zokulinganisa.

2. I-Phenolphthalein esetshenziswa ekwakhiweni kwezinto eziphilayo: i-phenolphthalein powder esetshenziswa kakhulu kumapulasitiki okwenziwa, ikakhulukazi ekwakhiweni kwama-polymer e-naphthyridine polyaryl ether ketone polyaryl ether ketone. Lolu hlobo lwe-polymer lunokumelana okuhle kakhulu nokushisa, ukumelana namanzi, kanye nokumelana namakhemikhali. Ngenxa yokumelana kwayo nokugqwala, ukumelana nokuguga kokushisa kanye nokucubungula okuhle kanye nokwakheka, imicu, izembozo kanye nezinto ezihlanganisiwe ezenziwe ngayo maduze nje zisetshenziswa kakhulu ezintweni zikagesi, imishini yemishini, ezokuthutha.

3. I-Phenolphthalein esetshenziswa njengenkomba yesisekelo se-asidi, inkomba ye-titration yezixazululo ezingezona ezamanzi, kanye ne-reagent yokuhlaziywa kwe-chromatographic.
