ʻIndene CAS 95-13-6

ʻO Indene, i ʻike ʻia hoʻi ʻo benzocyclopropene, he hydrocarbon aromatic polycyclic me ka haʻahaʻa o ka ʻawaʻawa a me ka huhū i ka ʻili kanaka a me nā membrane mucous. Loaʻa maoli ia i loko o ke kēpau lanahu a me ka ʻaila maka. Eia kekahi, hoʻokuʻu ʻia ka indene ke ʻole e puhi piha ʻia nā wahie mineral. Formula molekala C9H8. Kaumaha molekala 116.16. ʻO ke apo benzene a me ka cyclopentadiene i loko o kāna molekala e kaʻana like i ʻelua mau ʻātoma kalapona e pili ana. ʻIke ʻia ia he wai kala ʻole, ʻaʻole e hoʻoheheʻe i ka mahu, huli melemele ke kū mālie, akā nalowale ke kala ke hōʻike ʻia i ka lā. Helu heheʻe -1.8°C, kiko paila 182.6°C, kiko flash 58°C, density pili 0.9960 (25/4°C); hiki ʻole ke hoʻoheheʻe ʻia i ka wai, hui pū ʻia me ka ethanol a i ʻole ether. Loaʻa i nā molekala Indene nā pilina olefin ikaika loa, kahi i maʻalahi i ka polymerization a i ʻole nā ​​​​​​hopena hoʻohui. Hiki i ka Indene ke polymerize i ka mahana o ka lumi, a ʻo ka hoʻomehana ʻana a i ʻole ke alo o kahi mea hoʻoulu acidic hiki ke hoʻonui koke i ka wikiwiki o ka polymerization, a pane me ka waikawa sulfuric i hoʻopaʻa ʻia e hana i ka resin indene lua. Hoʻoheheʻe ʻia ʻo Indene (e ʻike i ka hopena hydrogenation catalytic) e hana i ka dihydroindene. ʻO ka hui methylene i loko o ka mole indene ua like ia me ka hui methylene i loko o ka mole cyclopentadiene. Hoʻomake maʻalahi ʻia a pane me ka sulfur e hana i kahi paʻakikī, nona ka hopena waikawa nāwaliwali a me nā waiwai hōʻemi. Hana ʻo Indene me ka sodium metala e hana i ka paʻakai sodium, a hoʻopili me nā aldehydes a me nā ketones (e ʻike i ka hopena condensation) e hana i ka benzofulvene: Hoʻokaʻawale ʻia ʻo Indene mai ka ʻāpana ʻaila māmā i loaʻa mai ka distillation o ke kēpau lanahu ma ka ʻoihana.
