Phenolphthalein CAS 77-09-8 ni iki?

Phenolphthalein ni aside organic idakomeye, igaragara nk'amakristu y'umweru cyangwa umuhondo muto ku bushyuhe bw'icyumba. Phenolphthalein 77-09-8 nta mpumuro kandi nta buryohe ifite. Phenolphthalein 77-09-8 iragoye gushonga mu mazi ariko ishongeshwa byoroshye muri alcool (ethanol) na ether. Phenolphthalein ishongeshwa mu gisubizo cya alcool kugira ngo ikore ikimenyetso cya aside-base. Phenolphthalein 77-09-8 nta ibara ifite mu gisubizo cya aside naho umutuku utukura mu gisubizo cya alkali cyangwa alkali metal carbonate. Ariko, iyo iri mu gisubizo cya alkali, izatanga aside trimetallic idafite ibara. Umunyu, ibara ritukura rirashira.

Porogaramu

1. Ibikoresho fatizo by’imiti bikoreshwa mu nganda zikora imiti: bibereye impatwe isanzwe kandi ikomeye, biboneka mu binini, mu byuma binini n’ibindi bipimo.

2. Phenolphthalein ikoreshwa mu gukora organic synthesis: ifu ya phenolphthalein ikoreshwa cyane cyane mu gukora pulasitiki zikozwe mu buryo bwa sintetike, cyane cyane mu gukora polymer za naphthyridine polyaryl ether ketone polyaryl ether ketone. Ubu bwoko bwa polymer bufite ubushobozi bwo kurwanya ubushyuhe, kurwanya amazi, no kurwanya imiti. Bitewe no kudakomera kwabwo, kudakomera kwabwo no gutunganya neza no gukora neza, fibres, coatings n'ibikoresho bivanze bikozwemo vuba aha bikoreshwa cyane mu bikoresho by'ikoranabuhanga, ibikoresho bya mekanike, ubwikorezi.

3. Phenolphthaleine ikoreshwa nk'ikimenyetso cy'ishingiro rya aside, ikimenyetso cy'uko imisemburo itari amazi ingana, n'ikimenyetso cy'isesengura rya chromatographic.
