Yintoni iPhenolphthalein CAS 77-09-8?

I-Phenolphthalein yi-asidi ebuthathaka ye-organic, ebonakala njengeekristale ezimhlophe okanye ezimthubi kancinci kubushushu begumbi. I-Phenolphthalein 77-09-8 ayinavumba kwaye ayinancasa. I-Phenolphthalein 77-09-8 kunzima ukuyinyibilikisa emanzini kodwa inyibilika lula kwi-alcohol (ethanol) kunye ne-ether. I-Phenolphthalein inyibilika kwisisombululo sotywala ukwenza isalathisi se-acid-base. I-Phenolphthalein 77-09-8 ayinambala kwisisombululo se-asidi kwaye ibomvu kwisisombululo se-alkali okanye kwisisombululo se-alkali metal carbonate. Nangona kunjalo, ukuba ikwisisombululo se-alkali esixineneyo, iya kuvelisa i-trimetallic acid engenambala. Ityuwa, umbala obomvu uyaphela

Isicelo

1. Izinto zokwenza amayeza kwishishini lamayeza: zilungele ukuqunjelwa okuqhelekileyo nokungakhathaliyo, ziyafumaneka kwiipilisi, iisuppositories kunye nezinye iindlela zokuthatha amayeza.

2. I-Phenolphthalein esetyenziswa kwi-organic synthesis: i-phenolphthalein powder esetyenziswa kakhulu kwi-synthetic plastics, ingakumbi kwi-naphthyridine polyaryl ether ketone polyaryl ether ketone polymers. Olu hlobo lwe-polymer lunokumelana okuhle nobushushu, ukumelana namanzi, kunye nokumelana neekhemikhali. Ngenxa yokumelana nokugqwala kwayo, ukumelana nokuguga kobushushu kunye nokucubungula kakuhle kunye nokwenziwa kakuhle, iifayibha, iingubo kunye nezinto ezidityanisiweyo ezenziwe ngayo kungekudala zisetyenziswa kakhulu kwizixhobo ze-elektroniki, izixhobo zoomatshini, uthutho.

3. I-Phenolphthalein isetyenziswa njengesalathisi se-asidi-base, isalathisi sokuthambeka kwezisombululo ezingezizo zamanzi, kunye ne-reagent yohlalutyo lwe-chromatographic.
