Ukusetyenziswa
Eyona ndlela iphambili yokusebenzisa i-phenolphthalein: 1. Ishishini lezamayeza njengezinto ezisetyenziswayo kumayeza: Lifanelekile ekuqunjelweni okuqhelekileyo nokungakhathaliyo kwaye lifumaneka kwiindlela ezahlukeneyo zokulinganisa ezifana neepilisi kunye neesuppositories. 2. Kwi-organic synthesis: Isetyenziswa kakhulu ekuhlanganiseni iiplastiki, ngakumbi ekuhlanganiseni ii-diazazone polyaryletherketone polymers. Ezi polymers zinokumelana okuhle nobushushu, ukumelana namanzi, ukumelana nokugqwala kweekhemikhali, ukumelana nokuguga kobushushu kunye nokusebenza kakuhle kunye nokwenziwa. Iifayibha, ii-coating kunye nezinto ezidityanisiweyo ezenziwe ngayo zasetyenziswa ngokukhawuleza kwiindawo ezifana nezixhobo ze-elektroniki kunye nombane, izixhobo zoomatshini, ezothutho, i-aerospace, ubunjineli bamandla e-athomu kunye nomkhosi. 3. Isetyenziswa njengesalathisi se-acid-base, isalathisi se-non-aqueous solution titration, kunye ne-reagent yohlalutyo lwe-chromatographic.
Le mveliso yiarhente ye-asidi esetyenziswa rhoqo, enoluhlu lokutshintsha kombala lwe-pH8.2 (ayinambala) -10.0 (ebomvu). I-Phenolphthalein ikwaluhlobo lonyango. Njengeyeza lokukhupha isisu, isebenza kumathumbu amakhulu kwaye isetyenziselwa ukunyanga ukuqhinwa.
Isetyenziswa njengesalathisi se-acid-base kunye ne-laxative evuselelayo yokunyanga ukuqhinwa
Izibonisi ze-asidi-base, izibonisi ze-titration yesisombululo esingengomanzi, ii-reagents zohlalutyo lwe-chromatographic.
Ukupakishwa kunye nokuthunyelwa
25KG/Idrama okanye ngokweemfuno zomthengi.
Yeyokwempahla eqhelekileyo kwaye inokuhanjiswa ngolwandle nangomoya
Gcina kwaye ugcine
Ixesha lokuphelelwa: Iinyanga ezingama-24 ukususela kumhla wokwenziwa kwayo kwiphakheji yokuqala engavulwanga igcinwe kwindawo epholileyo neyomileyo kude nelanga elithe ngqo, amanzi.
Indawo yokugcina umoya, Ukomisa kubushushu obuphantsi, Yahlulwe kwii-oxidants, ii-asidi.
