Fenolphthalein cas 77-09-8
Fenolphthalein ni acide kama idakomeye, igaragara nkibara ryera cyangwa umuhondo mutoya kristu nziza mubushyuhe bwicyumba.Ntabwo ari impumuro nziza kandi ntabwo iryoshye.Biragoye gushonga mumazi ariko byoroshye gushonga muri alcool (Ethanol) na ether.Irashonga mugisubizo cya alcool kugirango ikore aside-ishingiro.Ntibara rifite ibara rya acide na umutuku mubisubizo bya alkali cyangwa umuti wa karubone ya alkali.Ariko, niba iri mubisubizo bya alkali, bizatanga aside trimetallic idafite ibara.umunyu, ibara ry'umutuku rirashira

1. Ibikoresho fatizo bya farumasi yinganda zimiti: bikwiranye no kuribwa mu nda kandi binangiye, biboneka mu bisate, suppositions nubundi buryo bwa dosiye.
2. Fenolphthalein ikoreshwa muri synthesis organique: ikoreshwa cyane cyane muri plastiki yubukorikori, cyane cyane muri synthesis ya naphthyridine polyaryl ether ketone polyaryl ether ketone polymers.Ubu bwoko bwa polymer bufite imbaraga nziza zo kurwanya ubushyuhe, kurwanya amazi, no kurwanya imiti.Bitewe no kurwanya ruswa, kurwanya ubushyuhe bwo gusaza no gutunganya neza no guhinduka, fibre, coatings hamwe nibikoresho byinshi bikozwe muri yo bidatinze bikoreshwa cyane mubikoresho bya elegitoronike, ibikoresho bya mashini, ubwikorezi, ikirere, ingufu za kirimbuzi n’inganda za gisirikare.
3. Fenolphthalein ikoreshwa nkibipimo bya aside-fatizo, icyerekezo cyo gutondekanya ibisubizo bidafite amazi, na reagent yo gusesengura chromatografique.
