Iyini i-Indene CAS 95-13-6?

I-Indene, eyaziwa nangokuthi i-benzocyclopropene, iyi-hydrocarbon enuka kamnandi e-polycyclic enobuthi obuphansi kanye nokucasuka esikhumbeni somuntu kanye nolwelwesi lwama-mucous. Itholakala ngokwemvelo ku-coal tar kanye namafutha aluhlaza. Ngaphezu kwalokho, i-indene ikhishwa nalapho amafutha amaminerali engashiswanga ngokuphelele. Ifomula ye-molecular C9H8. Isisindo se-molecular 116.16. Indandatho ye-benzene kanye ne-cyclopentadiene ku-molecule yayo kubelana ngama-athomu amabili e-carbon aseduze. Ibonakala njengoketshezi olungenambala, ayiguquguquki emvuthweni, iphenduka iphuzi lapho ime, kodwa ilahlekelwa umbala lapho ivezwa elangeni. Iphuzu lokuncibilika -1.8°C, iphuzu lokubila 182.6°C, iphuzu lokufiphaza 58°C, ubuningi obuhlobene 0.9960 (25/4°C); ayincibiliki emanzini, ixubene ne-ethanol noma i-ether. Ama-molecule e-Indene aqukethe izibopho ze-olefin ezisebenza kakhulu ngamakhemikhali, ezivame ukuba ne-polymerization noma ukusabela kokungezwa. I-Indene ingapholimitha ekushiseni kwegumbi, futhi ukushisa noma lapho kukhona i-asidi catalyst kungakhuphula izinga le-polymerization kakhulu, futhi kusebenze nge-sulfuric acid egxilile ukuze kwakheke i-indene resin yesibili. I-Indene ipholimitha nge-catalytically hydrogenated (bheka i-catalytic hydrogenation reaction) ukuze kwakheke i-dihydroindene. Iqembu le-methylene ku-molecule ye-indene lifana neqembu le-methylene ku-molecule ye-cyclopentadiene. Ipholimitha kalula futhi isabela ne-sulfur ukuze ikhiqize i-complex, ene-acid reaction ebuthakathaka kanye nezakhiwo zokunciphisa. I-Indene isabela ne-metallic sodium ukuze yakhe usawoti we-sodium, futhi ihlangana ne-aldehydes nama-ketone (bheka i-condensation reaction) ukuze kwakheke i-benzofulvene: I-Indene ihlukaniswe nengxenyeni kawoyela ekhanyayo etholakala ekuhluzweni kwe-coal tar embonini.

Isicelo

I-Indene isetshenziswa kakhulu ukukhiqiza i-indene-coumarone resin. Izinto zokusetshenziswa ze-indene-coumarone resin yi-fraction engu-160-215°C ehlutshiwe kusuka kuma-fraction e-benzene asindayo kanye namafutha alula, aqukethe cishe i-styrene engu-6%, i-coumarone engu-4%, i-indene engu-40%, i-5% i-4-methylstyrene kanye nenani elincane le-xylene, i-toluene kanye nezinye izinto ezihlanganisiwe. Inani eliphelele le-resin libalelwa ku-60-70% wezinto zokusetshenziswa ze-Chemicalbook. Ngaphansi kwesenzo sezinto ezibangela ukucindezeleka ezifana ne-aluminium chloride, i-boron fluoride noma i-sulfuric acid egxilile, ama-fraction e-indene kanye ne-coumarone ahlanganiswa nge-polymer ngaphansi kwengcindezi noma ngaphandle kwengcindezi yokukhiqiza i-indene-coumarone resin. Ingaxutshwa namanye ama-hydrocarbons ewuketshezi njengesithako sokumboza. Ingaphinde ibe yingxenye yezibulala-zinambuzane noma ixutshwe namanye ama-hydrocarbons ewuketshezi njengesithako sokumboza.
