Okwu mmalite

Oxyindene (C9H6O2) bụ ngwakọta organic nwere mgbanaka benzene na mgbanaka benzofuran. Ihe na-esonụ bụ mmalite nke akụrụngwa, ojiji, ụzọ nkwadebe na ozi nchekwa nke oxyidene:

 

Ogo:

Ọdịdị: Oxyindene bụ kristal na-acha odo odo na-enweghị ụcha.

Solubility: Enwere ike ịgbaze Oxyindene n'ọtụtụ ihe mgbaze organic, mana ọ naghị agbaze na mmiri.

 

Jiri:

A pụkwara iji Oxindene mee ihe dị ka ihe mgbakwunye na fotosensitizers na polymer stabilizers.

 

Usoro:

Enwere ike ịkwadebe Oxyindene site na mmeghachi omume oxidation nke benzofuran na benzofuranone. Usoro nkwadebe a kapịrị ọnụ nwere ike ịgụnye usoro dị mgbagwoju anya na njikọ organic, nke na-achọkarị ngwa nke oxidant n'okpuru ọnọdụ kwesịrị ekwesị.

 

Ozi nchekwa:

A na-ahụta Oxyindene dị ka ihe dị oke nchebe n'okpuru ọnọdụ eji eme ihe, mana ọ ka na-achọ nnabata na usoro arụ ọrụ kwesịrị ekwesị na ụlọ nyocha na mmepụta mmepụta ihe.

Mgbe a na-eji oxyyindene eme ihe, a ga-eyi akụrụngwa nchedo onwe onye kwesịrị ekwesị dị ka uwe kemịkalụ, enyo enyo, na uwe nchebe.

Zere kọntaktị na akpụkpọ ahụ na anya, ma zere ikuku ume ma ọ bụ iri oxyindene.

Ekwesịrị ịchekwa Oxyindene n'ime akpa ikuku na-adịghị na mgbanye ọkụ na oxidants.
