Izithako ze-Apis ezidumile kakhulu I-Phenolphthalein Powder
Sithembele emandleni obuchwepheshe aqinile futhi sihlala sakha ubuchwepheshe obusezingeni eliphezulu ukuze sihlangabezane nesidingo sezithako ze-Apis ezidumile kakhulu. I-Phenolphthalein Powder, Siqotho futhi sivulekile. Silangazelela ukuvakasha kwakho kanye nokwakha ubudlelwano obuthembekile nobuhlala isikhathi eside.
Sithembele emandleni obuchwepheshe aqinile futhi sihlala sakha ubuchwepheshe obuyinkimbinkimbi ukuze sihlangabezane nesidingoI-China CAS 77-09-8 kanye ne-Einecs 201-004-7, Inkampani yethu ibheka "amanani afanele, ikhwalithi ephezulu, isikhathi sokukhiqiza esisebenzayo kanye nensizakalo enhle yangemva kokuthengisa" njengesimiso sethu. Sithemba ukubambisana namakhasimende amaningi ukuze kuthuthukiswe futhi kuzuze ngokubambisana esikhathini esizayo. Siyakwamukela ukuxhumana nathi.
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.
