Yintoni iPhenolphthalein cas 77-09-8?

I-Phenolphthalein yi-asidi ye-organic ebuthathaka, ebonakala njengeekristale ezimhlophe okanye ezityheli kancinci kwiqondo lobushushu begumbi. Ayinavumba kwaye ayinancasa. Kunzima ukunyibilika emanzini kodwa kulula ukunyibilika etywaleni (ethanol) kunye ne-ether. Ichithwa kwisisombululo sotywala ukwenza isalathisi se-acid-base. Ayinambala kwisisombululo esine-acidic kwaye ibomvu kwisisombululo se-alkali okanye isisombululo se-alkali sesinyithi se-carbonate. Nangona kunjalo, ukuba ikwisisombululo esigxininisiweyo se-alkali, iya kuvelisa i-asidi ye-trimetallic engenambala. ityuwa, umbala obomvu uyaphela

Isicelo

1. Imathiriyeli ekrwada yamayeza kwishishini loxubo mayeza: ilungele ukuqunjelwa okuqhelekileyo kunye nenkani, ekhoyo kwiipilisi, ii-suppositories kunye nezinye iifom zedosi.

2. I-Phenolphthalein esetyenziswe kwi-organic synthesis: isetyenziselwa ikakhulu iiplastiki zokwenziwa, ngokukodwa ukuhlanganiswa kwe-naphthyridine polyaryl ether ketone polyaryl ether ketone polymers. Olu hlobo lwepolymer lunamandla okumelana nobushushu, ukunganyangeki kwamanzi, kunye nokumelana neekhemikhali. Ngenxa yokunganyangeki kwe-corrosion, ukumelana nokuguga kobushushu kunye nokusebenza kakuhle kunye nokwakheka, iifayibha, iingubo kunye nezinto ezidibeneyo ezenziwe kuyo ngokukhawuleza zisetyenziswa ngokubanzi kwizixhobo zombane, izixhobo zoomatshini, ukuthutha, i-aerospace, ubunjineli bamandla e-athomu kunye nemimandla yasemkhosini.

3. I-Phenolphthalein esetyenziswe njengesalathisi se-acid-base, isalathisi se-titration yezisombululo ezingenamanzi, kunye ne-reagent yohlalutyo lwe-chromatographic.
