Waa maxay Phenolphthalein CAS 77-09-8?

Phenolphthalein waa aashito dabiici ah oo daciif ah, taasoo u muuqata sida kiristaalo cad ama huruud yar oo khafiif ah heerkulka qolka. Phenolphthalein 77-09-8 waa mid aan ur lahayn oo aan dhadhan lahayn. Phenolphthalein 77-09-8 way adag tahay in lagu milmo biyaha laakiin si fudud ayaa loogu milmaa khamriga (ethanol) iyo ether. Phenolphthalein waxaa lagu milmaa xalka khamriga si loo sameeyo tilmaame saldhig aashito ah. Phenolphthalein 77-09-8 waa mid aan midab lahayn xalka aashitada iyo casaanka xalka alkali ama xalka alkali birta carbonate. Si kastaba ha ahaatee, haddii ay ku jirto xalka alkali ee xooggan, waxay soo saari doontaa aashito trimetallic ah oo aan midab lahayn. milix, midab casaan ah ayaa libdhaya.

Codsiga

1. Alaabada ceeriin ee dawooyinka ee warshadaha dawooyinka: ku habboon calool istaagga caadiga ah iyo kan adag, oo laga heli karo kiniinno, suppositories iyo qaabab kale oo qiyaas ah.

2. Phenolphthalein oo loo isticmaalo isku-darka dabiiciga ah: budada phenolphthalein waxaa inta badan loo isticmaalaa balaastikada macmal ah, gaar ahaan isku-darka naphthyridine polyaryl ether ketone polymers-ka polyaryl ether ketone. Noocan polymer-ku wuxuu leeyahay iska caabin kulayl oo aad u fiican, iska caabin biyo, iyo iska caabin kiimiko. Sababtoo ah iska caabintiisa daxalka, iska caabinta gabowga kulaylka iyo habaynta iyo qaabaynta wanaagsan, fiilooyinka, dahaarka iyo walxaha isku-dhafan ee laga sameeyay ayaa dhawaan si weyn loogu isticmaalaa qalabka elektaroonigga ah, qalabka farsamada, gaadiidka.

3. Phenolphthalein oo loo isticmaalo tilmaame saldhig aashito ah, tilmaame lagu titration of xalalka aan biyaha lahayn, iyo falanqeeye loogu talagalay falanqaynta koromografiga.
