Indene CAS 95-13-6

ʻO Indene, i kapa ʻia ʻo benzocyclopropene, he polycyclic aromatic hydrocarbon me ka haʻahaʻa haʻahaʻa a me ka huhū i ka ʻili kanaka a me nā membrane mucous. Aia maoli ia i loko o ka lanahu a me ka ʻaila ʻaila. Eia kekahi, hoʻokuʻu ʻia ka indene ke pau ʻole ka pau ʻana o nā wahie mineral. Huina molekala C9H8. Kaumaha Molekala 116.16. ʻO ke apo benzene a me ka cyclopentadiene i loko o kona mole e kaʻana like ʻelua mau ʻātoma kalapona pili. ʻIke ʻia me he wai waihoʻoluʻu ʻole, ʻaʻole lili i ka mahu, huli melemele ke kū mālie, akā nalowale ke kala ke ʻike ʻia i ka lā. Ka helu heheʻe -1.8°C, kahi e hoʻolapalapa ai 182.6°C, kiko uila 58°C, mānoanoa pili 0.9960 (25/4°C); hiki ʻole ke hoʻoheheʻe ʻia i ka wai, hiki ke hoʻopili ʻia me ka ethanol a i ʻole etera. Loaʻa i nā molekala Indene nā mea hoʻopaʻa ʻolefin kemika ikaika loa, hiki i ka polymerization a i ʻole ka hoʻohui ʻana. Hiki i ka Indene ke polymerize ma ka lumi wela, a ʻo ka hoʻomehana ʻana a i ʻole ke alo o kahi catalyst acidic hiki ke hoʻonui i ka nui o ka polymerization, a hana me ka sulfuric acid concentrated e hana i ka resin indene lua. ʻO ka Indene i hoʻoheheʻe ʻia (e ʻike i ka hopena hydrogenation catalytic) e hana i ka dihydroindene. Ua like ka pūʻulu methylene i loko o ka mole indene me ka pūʻulu methylene i loko o ka mole cyclopentadiene. He maʻalahi ka hoʻoheheʻe ʻia a hoʻopili ʻia me ka sulfur e hana i kahi paʻakikī, nona ka hopena ʻakika nāwaliwali a me ka hoʻemi ʻana i nā waiwai. Hoʻopili ʻo Indene me ka sodium metala e hana ai i ka paʻakai sodium, a hoʻopaʻa ʻia me nā aldehydes a me nā ketones (e ʻike i ka hopena condensation) e hana i benzofulvene: Ua hoʻokaʻawale ʻia ʻo Indene mai ka hakina aila māmā i loaʻa mai ka hoʻoheheʻe ʻana o ka lanahu ma ka ʻoihana.
