Indene CAS 95-13-6
Indene, e tsejoang hape e le benzocyclopropene, ke polycyclic e nkhang hamonate ea hydrocarbon e nang le chefo e tlase le ho teneha letlalong la motho le lera la mucous. E fumaneha ka tlhaho ka har'a sekontiri sa mashala le oli e tala. Ho phaella moo, indene e boetse e lokolloa ha mafura a liminerale a sa chesoe ka ho feletseng. Foromo ea molek'hule C9H8. Boima ba molek'hule 116.16. Lesale la benzene le cyclopentadiene molek'huleng ea eona li arolelana liathomo tse peli tsa khabone. E bonahala e le mokelikeli o se nang 'mala, ha o fetohe mouoane, o fetoha mosehla ha o eme, empa o lahleheloa ke 'mala ha o le letsatsing. Ntho e qhibilihisang -1.8 ° C, ntlha e belang 182.6 ° C, ntlha ea flash - 58 ° C, sekhahla se lekanyelitsoeng 0.9960 (25/4 ° C); e sa qhibidihang metsing, e kopane le ethanol kapa ether. Limolek'hule tsa Indene li na le li-olefin tse nang le lik'hemik'hale tse sebetsang haholo, tse atisang ho ba le polymerization kapa ho eketsa karabelo. Indene e ka etsa polymerize ka mocheso oa kamore, 'me ho futhumatsa kapa ka boteng ba acidic catalyst ho ka eketsa sekhahla sa polymerization haholo,' me ea itšoara ka concentrated sulfuric acid ho theha resin ea bobeli ea inde. Indene ke catalytically hydrogenated (sheba catalytic hydrogenation reaction) ho etsa dihydroindene. Sehlopha sa methylene ka molek'hule ea indene se tšoana le sehlopha sa methylene ka molek'hule ea cyclopentadiene. E na le oxidized habonolo mme e sebetsana le sebabole ho hlahisa motsoako, o nang le boikutlo bo fokolang ba acid le ho fokotsa thepa. Indene e sebetsana le metallic sodium ho etsa letsoai la sodium, mme e kopana le aldehydes le ketones (sheba condensation reaction) ho etsa benzofulvene: Indene e arotsoe ho karolo ea oli e bobebe e fumanoang ho tsoa ho distillation ea sekontiri sa mashala indastering.

Indene e sebelisoa haholo-holo ho hlahisa indene-coumarone resin. Thepa e tala ea indene-coumarone resin ke karolo ea 160-215 ° C e qhibilihisitsoeng ho tloha ho benzene e boima le likaroloana tsa oli tse bobebe, tse batlang li na le 6% styrene, 4% coumarone, 40% indene, 5% 4-methylstyrene le tekanyo e nyenyane ea xylene, toluene le metsoako e meng. Palo eohle ea resin e etsa 60-70% ea lisebelisoa tse tala tsa Chemicalbook. Tlas'a ketso ea li-catalysts tse kang aluminium chloride, boron fluoride kapa concentrated sulfuric acid, likaroloana tsa indene le coumarone li entsoe ka polymer ka tlas'a khatello kapa ntle le khatello ea ho hlahisa indene-coumarone resin. E ka tsoakoa le li-hydrocarbon tse ling tsa metsi joalo ka mokelikeli oa ho roala. E ka boela ea e-ba karolo e bohareng ea chefo e bolaeang likokoanyana kapa e kopantsoe le li-hydrocarbon tse ling tse metsi e le motsoako oa ho roala.
