Chii chinonzi Phenolphthalein CAS 77-09-8?

Phenolphthalein iasidhi isina simba, inoonekwa semakristaro machena kana kuti yero zvishoma patembiricha yemumba. Phenolphthalein 77-09-8 haina hwema uye haina kunaka. Phenolphthalein 77-09-8 inonetsa kunyungudika mumvura asi inonyungudika nyore nyore mualcohol (ethanol) ne ether. Phenolphthalein inonyungudika mualcohol solution kuti iite acid-base indicator. Phenolphthalein 77-09-8 haina ruvara mu acidic solution uye tsvuku mu alkali solution kana alkali metal carbonate solution. Zvisinei, kana iri mu concentrated alkali solution, inoburitsa trimetallic acid isina ruvara. Munyu, ruvara rutsvuku runopera

Kushandiswa

1. Zvinhu zvemishonga zveindasitiri yemishonga: zvakakodzera kuvimbirwa kwakajairika uye kwakaoma, zvinowanikwa mumapiritsi, suppositories nedzimwe nzira dzekurapa.

2. Phenolphthalein inoshandiswa mukugadzirwa kwezvinhu zvakasikwa: upfu hwephenolphthalein hunonyanya kushandiswa mumapurasitiki ekugadzira, kunyanya mukugadzirwa kwemapolymer e naphthyridine polyaryl ether ketone polyaryl ether ketone. Rudzi urwu rwepolymer runodzivirira kupisa zvakanyanya, runodzivirira mvura, uye runodzivirira makemikari. Nekuda kwekudzivirira kwayo ngura, kudzivirira kupisa kukwegura uye kugadziriswa zvakanaka uye kugadzirwa zvakanaka, fibers, coatings nezvinhu zvakagadzirwa kubva mairi zvinokurumidza kushandiswa zvakanyanya mumidziyo yemagetsi, michina, kutakura.

3. Phenolphthalein inoshandiswa sechiratidzo cheacid-base, chiratidzo chekuyera kwemvura isina mvura, uye reagent yekuongorora chromatographic.
