    Manje sinabasebenzi abangochwepheshe nabasebenzayo abahlinzeka ngomhlinzeki wekhwalithi ephezulu kumakhasimende ethu. Ngokuvamile silandela umgomo wokugxila kumakhasimende, imininingwane egxile ekuthengiseni okushisayoInombolo ye-CAS 77-09-8 Phenolphthalein 99%MW 318.32, Samukela amakhasimende, izinhlangano zebhizinisi kanye nabangani abavela kuzo zonke izingxenye zomhlaba ukuthi basithinte futhi bafune ukubambisana ukuze kuzuze bonke.

Ngokuvamile silandela umgomo wokubheka amakhasimende, ugxile emininingwaneni.I-China CAS No. 77-09-8 kanye ne-PhenolphthaleinSiyakwamukela ukuthi uvakashele inkampani yethu kanye nefektri futhi indawo yethu yokubonisa ibonisa izinto ezahlukahlukene ezizohlangabezana nokulindelekile kwakho. Okwamanje, kulula ukuvakashela iwebhusayithi yethu. Abasebenzi bethu bokuthengisa bazozama konke okusemandleni abo ukukunikeza izinsizakalo ezinhle kakhulu. Uma udinga ulwazi olwengeziwe, qiniseka ukuthi ungangabazi ukusithinta nge-imeyili, ifeksi noma ucingo.

    I-Phenolphthaleiniyi-asidi ebuthakathaka e-organic, ebonakala njengamakristalu amhlophe noma aphuzi kancane ekushiseni kwegumbi. Ayinaphunga futhi ayinambitheki. Kunzima ukuyincibilikisa emanzini kodwa incibilika kalula ku-alcohol (ethanol) kanye ne-ether. Incibilika kusisombululo sotshwala ukuze yenze inkomba ye-acid-base. 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

    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: isetshenziswa 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, izindiza, ubunjiniyela bamandla e-athomu kanye nezinkundla zempi.

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