O le a le Phenolphthalein cas 77-09-8?

O le Phenolphthalein ose vaila'au vaivai vaivai, e foliga mai o ni tioata pa'epa'e po'o sina samasama i le vevela o le potu. E leai se manogi ma leai se tofo. E faigata ona solo i le vai ae faigofie ona solu ile ava malosi (ethanol) ma le eter. E fa'amavae i le vaifofo o le 'ava malosi e fai ai se fa'ailo fa'amaufa'ailoga. E leai se lanu i le vaifofo oona ma mumu i le alkali solution po'o le alkali metal carbonate solution. Ae peita'i, afai o lo'o iai i totonu ole vaifofo fa'amama ole alkali, ole a maua mai ai le acid trimetallic colorless. masima, lanu mumu e mou atu

Fa'atatauga

1. Pharmaceutical raw materials for the pharmaceutical industry: e talafeagai mo le masani ma le faʻamaʻaʻa o le manava, e maua i papa, suppositories ma isi ituaiga vailaʻau.

2. Phenolphthalein faʻaaogaina i le faʻaogaina o meaola: e masani ona faʻaaogaina mo palasitika gaosia, aemaise lava mo le faʻaogaina o le naphthyridine polyaryl ether ketone polyaryl ether ketone polymers. O lenei ituaiga polymer e sili ona lelei le vevela, faʻafefe vai, ma vailaʻau. Ona o lona tete'e o le corrosion, vevela matua tetee ma lelei faagasologa ma formability, alava, coatings ma mea composite faia mai ai e le o toe umi ae faaaogaina lautele i mea faaeletonika, masini masini, felauaiga, aerospace, atomic malosiaga inisinia ma fanua militeli.

3. Fa'aaoga le Phenolphthalein e fai ma fa'ailo fa'avae oona, fa'ailo mo le fa'avasegaina o vaifofo e le fa'afefeteina, ma le reagent mo su'esu'ega chromatographic.
