Indene CAS 95-13-6

Indene, nke a makwaara dịka benzocyclopropene, bụ polycyclic aromatic hydrocarbon nke nwere obere nsí na mgbakasị ahụ na akpụkpọ ahụ mmadụ na akpụkpọ ahụ mucous. Ọ dị n'okike na coal tar na mmanụ nkịtị. Na mgbakwunye, a na-ewepụtakwa indene mgbe mmanụ mineral anaghị ere ọkụ kpamkpam. Usoro molekul C9H8. Ibu molekul 116.16. Mgbanaka benzene na cyclopentadiene dị na molekul ya nwere atọm carbon abụọ dị n'akụkụ. Ọ na-apụta dị ka mmiri mmiri na-enweghị agba, ọ naghị agbanwe agbanwe na uzuoku, na-agbanwe odo mgbe ọ kwụ ọtọ, mana ọ na-efunahụ agba mgbe a na-ekpughe ya na anwụ. Ebe agbaze -1.8°C, ebe esi mmiri 182.6°C, ebe ọkụ 58°C, njupụta dị n'etiti 0.9960 (25/4°C); anaghị agbaze na mmiri, a na-agwakọta ya na ethanol ma ọ bụ ether. molekul Indene nwere njikọ olefin na-arụ ọrụ nke ukwuu na kemịkalụ, nke na-adịkarị mfe ime ka polymerization ma ọ bụ mgbakwunye meghachi omume. Indene nwere ike ime ka ọ dị mma n'ime ụlọ, ikpo ọkụ ma ọ bụ n'ihu ihe na-akpali acid nwere ike ime ka ọnụego polymerization dịkwuo elu nke ukwuu, ma meghachi omume na sulfuric acid a chịkọtara iji mepụta resin indene nke abụọ. Indene na-eme ka hydrogenated dị na catalytically (lee mmeghachi omume hydrogenation catalytic) iji mepụta dihydroindene. Otu methylene dị na molekul indene yiri otu methylene dị na molekul cyclopentadiene. A na-eme ka ọ dị mfe oxidize ma na-emeghachi omume na sulfur iji mepụta ihe mgbagwoju anya, nke nwere mmeghachi omume acid na-adịghị ike na ihe onwunwe na-ebelata. Indene na-emeghachi omume na sodium metal iji mepụta nnu sodium, ma na-agwakọta ya na aldehydes na ketones (lee mmeghachi omume condensation) iji mepụta benzofulvene: A na-ekewa Indene na obere mmanụ ọkụ nke a na-enweta site na distillation nke coal tar na ụlọ ọrụ.
