He aha ka Phenolphthalein CAS 77-09-8?

He waikawa organik nāwaliwali ka Phenolphthalein, kahi e ʻike ʻia me he mau kristal keʻokeʻo a melemele iki paha i ka mahana o ka lumi. ʻAʻohe ʻala a ʻono ʻole ka Phenolphthalein 77-09-8. He paʻakikī ke hoʻoheheʻe ʻia ka Phenolphthalein 77-09-8 i ka wai akā maʻalahi ke hoʻoheheʻe ʻia i ka waiʻona (ethanol) a me ka ether. Hoʻoheheʻe ʻia ka Phenolphthalein i loko o ka waiʻona e hana i kahi hōʻailona acid-base. ʻAʻohe kala o ka Phenolphthalein 77-09-8 i loko o ka waiʻona waikawa a ʻulaʻula i loko o ka waiʻona alkali a i ʻole ka waiʻona alkali metal carbonate. Eia nō naʻe, inā aia i loko o ka waiʻona alkali i hoʻopaʻa ʻia, e hana ia i ka waikawa trimetallic kala ʻole. paʻakai, mae ke kala ʻulaʻula

1. Nā mea lāʻau lapaʻau maka no ka ʻoihana lāʻau lapaʻau: kūpono no ka paʻa mau a paʻakikī hoʻi, loaʻa i nā papa, nā suppositories a me nā ʻano dosage ʻē aʻe.

2. Hoʻohana ʻia ka Phenolphthalein i ka synthesis organik: ʻo ka pauka phenolphthalein i hoʻohana nui ʻia no nā plastics synthetic, ʻoi aku hoʻi no ka synthesis o nā polymers naphthyridine polyaryl ether ketone polyaryl ether ketone. Loaʻa i kēia ʻano polymer ke kūpaʻa wela maikaʻi loa, kūpaʻa wai, a me ke kūpaʻa kemika. Ma muli o kona kūpaʻa i ka pala, kūpaʻa i ka wela a me ka hana maikaʻi a me ke ʻano, ua hoʻohana nui ʻia nā fibers, nā uhi a me nā mea i hana ʻia mai ia mea i nā mīkini uila, nā lako mīkini, a me ka halihali.

3. Hoʻohana ʻia ka Phenolphthalein ma ke ʻano he anakahi acid-base, anakahi no ka titration o nā hopena ʻaʻole wai, a me ka reagent no ka nānā ʻana i ka chromatographic.
