Factory For Factory High Quality Research Reagent Phenolphthalein CAS 77-09-8
Tikukhulupirira kuti ndi mgwirizano, bizinesi yathu idzatibweretsera phindu limodzi. Tikhoza kukutsimikizirani mosavuta kuti katundu wanu ndi wabwino komanso mtengo wake ndi wapamwamba kwambiri.CAS 77-09-8Ngati mukufuna kampani yabwino, yotumiza mwachangu, yabwino kwambiri yotumizira pambuyo pa ntchito komanso yogulitsa pamtengo wabwino ku China kuti mukhale ndi ubale wa nthawi yayitali ndi bizinesi, tidzakhala chisankho chanu chabwino kwambiri.

Kuphatikiza apo, tsopano tili ndi malo athu osungiramo zinthu zakale komanso misika ku China pamtengo wotsika. Chifukwa chake, titha kufunsa mafunso osiyanasiyana kuchokera kwa makasitomala osiyanasiyana. Kumbukirani kupeza tsamba lathu lawebusayiti kuti muwone zambiri kuchokera kuzinthu zathu.
Phenolphthalein ndi asidi wofooka wa organic, womwe umawoneka ngati makhiristo oyera kapena achikasu pang'ono kutentha kwa chipinda. Ndi wopanda fungo komanso wopanda kukoma. Ndi wovuta kusungunuka m'madzi koma umasungunuka mosavuta mu mowa (ethanol) ndi ether. Umasungunuka mu yankho la mowa kuti upange chizindikiro cha acid-base. Ndi wopanda mtundu mu yankho la acidic ndipo ndi wofiira mu yankho la alkali kapena yankho la alkali metal carbonate. Komabe, ngati uli mu yankho la alkali lokhazikika, umapanga trimetallic acid yopanda mtundu. Mchere, mtundu wofiira umatha

1. Zipangizo zopangira mankhwala zogwiritsidwa ntchito m'makampani opanga mankhwala: zoyenera kudzimbidwa kosalekeza komanso kosalekeza, zomwe zimapezeka m'mapiritsi, m'mapiritsi ndi m'njira zina zoyezera.
2. Phenolphthalein yomwe imagwiritsidwa ntchito popanga zinthu zachilengedwe: imagwiritsidwa ntchito makamaka popanga mapulasitiki opangidwa, makamaka popanga ma polima a naphthyridine polyaryl ether ketone polyaryl ether ketone. Mtundu uwu wa polima uli ndi kukana kutentha bwino, kukana madzi, komanso kukana mankhwala. Chifukwa cha kukana dzimbiri, kukana kutentha komanso kukonza bwino komanso kupanga bwino, ulusi, zokutira ndi zinthu zopangidwa kuchokera pamenepo zikugwiritsidwa ntchito kwambiri posachedwa mu zida zamagetsi, zida zamakanika, mayendedwe, ndege, uinjiniya wa mphamvu za atomiki ndi minda yankhondo.
3. Phenolphthalein yogwiritsidwa ntchito ngati chizindikiro cha acid-base, chizindikiro cha titration ya mayankho osakhala amadzi, komanso reagent yowunikira chromatographic.

Fakitale yaChina Mankhwala ndi Chakudya Zowonjezera, Tili ndi mainjiniya apamwamba m'mafakitale awa komanso gulu lochita bwino pa kafukufukuyu. Kuphatikiza apo, tsopano tili ndi malo athu osungiramo zinthu zakale komanso misika ku China pamtengo wotsika. Chifukwa chake, titha kufunsa mafunso osiyanasiyana kuchokera kwa makasitomala osiyanasiyana. Kumbukirani kupeza tsamba lathu lawebusayiti kuti muwone zambiri kuchokera kuzinthu zathu.
