Indene CAS 95-13-6
I-Indene, eyaziwa nangokuthi i-benzocyclopropene, iyi-polycyclic enuka kamnandi enobuthi obuphansi nokucasuka esikhumbeni somuntu kanye nolwelwesi lwamafinyila. Itholakala ngokwemvelo kwitiyela yamalahle nasemafutheni angahluziwe. Ngaphezu kwalokho, i-inde iphinde ikhishwe lapho amafutha amaminerali engashiswa ngokuphelele. Ifomula ye-molecular C9H8. Isisindo se-molecule 116.16. Iringi ye-benzene ne-cyclopentadiene ku-molecule yayo yabelana ngama-athomu ekhabhoni amabili ancikene. Ibonakala iwuketshezi olungenambala, ayishisi emhwamukeni, ibe phuzi lapho imile, kodwa ilahlekelwa umbala lapho ichayeke elangeni. Iphuzu elincibilikayo -1.8°C, iphoyinti elibilayo lingu-182.6°C, iphuzu elikhanyayo lingu-58°C, ukuminyana kwesihlobo 0.9960 (25/4°C); engancibiliki emanzini, ihlangana ne-ethanol noma i-ether. Ama-molecule e-Indene aqukethe amabhondi e-olefin asebenza kakhulu ngamakhemikhali, athambekele ekwenzeni i-polymerization noma ukusabela kokwengezwa. I-Indene ingakwazi ukwenza polymerize ekamelweni lokushisa, futhi ukufudumeza noma phambi kwe-acidic catalyst kungakhuphula izinga le-polymerization ngokucijile, futhi kusabela nge-concentrated sulfuric acid ukuze kwakheke inhlaka yesibili ye-inde. I-Indene i-catalytically hydrogenated (bona i-catalytic hydrogenation reaction) ukuze yakhe i-dihydroindene. Iqembu le-methylene ku-molecule ye-inde lifana neqembu le-methylene ku-molecule ye-cyclopentadiene. I-oxidized kalula futhi isabela ngesulfure ukukhiqiza inkimbinkimbi, ene-acid reaction ebuthakathaka kanye nezakhiwo zokunciphisa. I-Indene isabela ne-metallic sodium ukwenza usawoti we-sodium, futhi ihlangana nama-aldehyde nama-ketones (bona ukusabela kokujiya) ukwenza i-benzofulvene: I-Indene ihlukaniswa nengxenye kawoyela okhanyayo etholakala ekucwilisweni kwetiyela yamalahle embonini.

I-Indene isetshenziswa kakhulu ukukhiqiza i-indene-coumarone resin. I-raw material ye-indene-coumarone resin iyingxenyana engu-160-215°C egaywe kusuka ku-benzene esindayo kanye nezingxenyana zamafutha alula, cishe aqukethe u-6% we-styrene, u-4% we-coumarone, u-40% we-indene, u-5% 4-methylstyrene kanye nenani elincane le-xylene, i-toluene nezinye izinhlanganisela. Isamba senani leresin libalelwa ku-60-70% wezinto zokusetshenziswa ze-Chemicalbook. Ngaphansi kwesenzo sama-catalysts afana ne-aluminium chloride, i-boron fluoride noma i-concentrated sulfuric acid, i-indene ne-coumarone izingxenyana ze-polymerized ngaphansi kwengcindezi noma ngaphandle kwengcindezi yokwenza i-indene-coumarone resin. Ingaxutshwa namanye ama-hydrocarbon awuketshezi njenge-solvent enamathelayo. Kungase futhi kube isibulala-zinambuzane esiphakathi nendawo noma exutshwe namanye ama-hydrocarbon awuketshezi njengesincibilikisi esinamathelayo.
