Yintoni i-Indene CAS 95-13-6?

I-Indene, eyaziwa ngokuba yi-benzocyclopropene, yi-hydrocarbon enuka kamnandi ene-polycyclic enobuthi obuphantsi kunye nokucaphuka okuncinci kulusu lomntu kunye nee-membranes ze-mucous. Ifumaneka ngokwemvelo kwi-coal tar kunye ne-oyile ekrwada. Ukongeza, i-indene ikwakhutshwa xa amafutha eeminerali engatshiswanga ngokupheleleyo. Ifomula yemolekyuli C9H8. Ubunzima bemolekyuli 116.16. Indandatho yebenzene kunye ne-cyclopentadiene kwimolekyuli yayo zabelana ngeeathom ezimbini zekhabhoni ezikufutshane. Ibonakala njengolwelo olungenambala, aluguquguquki kumphunga, lujika lube tyheli xa lumi, kodwa lulahlekelwa ngumbala xa luvezwa lilanga. Inqanaba lokunyibilika -1.8°C, inqanaba lokubila 182.6°C, inqanaba le-flash 58°C, uxinano oluhambelanayo 0.9960 (25/4°C); ayinyibiliki emanzini, ixutywa ne-ethanol okanye i-ether. Iimolekyuli ze-Indene ziqulathe iibhondi ze-olefin ezisebenzayo kakhulu kwiikhemikhali, ezinokuthi zisetyenziswe kwi-polymerization okanye kwi-addition reactions. I-Indene ingenza i-polymerize kubushushu begumbi, kwaye ukufudumala okanye xa kukho i-acidic catalyst kunokunyusa izinga le-polymerization ngokukhawuleza, kwaye kusebenze nge-sulfuric acid egxininisiweyo ukuze kwenziwe i-indene resin yesibini. I-Indene i-catalytically hydrogenated (jonga i-catalytic hydrogenation reaction) ukuze yenze i-dihydroindene. Iqela le-methylene kwi-indene molecule lifana neqela le-methylene kwi-cyclopentadiene molecule. I-oxidized lula kwaye isabela ne-sulfur ukuze ivelise i-complex, ene-acid reaction ebuthathaka kunye neempawu zokunciphisa. I-Indene isabela ne-metallic sodium ukwenza ityuwa ye-sodium, kwaye ihlangana ne-aldehydes kunye nee-ketones (jonga i-condensation reaction) ukuze yenze i-benzofulvene: I-Indene yahlulwe kwi-light oil fraction efunyenwe kwi-distillation ye-coal tar kushishino.

Isicelo

I-Indene isetyenziswa kakhulu ukuvelisa i-indene-coumarone resin. Izinto eziluhlaza ze-indene-coumarone resin yi-160-215°C fraction edityaniswe kwi-benzene enzima kunye nee-oyile ezikhanyayo, equlethe malunga ne-6% styrene, i-4% coumarone, i-40% indene, i-5% 4-methylstyrene kunye nenani elincinci le-xylene, i-toluene kunye nezinye iikhompawundi. Isixa sisonke se-resin sibandakanya i-60-70% yezinto eziluhlaza zeChemicalbook. Phantsi kwesenzo se-catalysts ezifana ne-aluminium chloride, i-boron fluoride okanye i-concentrated sulfuric acid, ii-indene kunye ne-coumarone fractions zenziwa i-polymer phantsi koxinzelelo okanye ngaphandle koxinzelelo lokuvelisa i-indene-coumarone resin. Ingaxutywa nezinye ii-hydrocarbons ezingamanzi njengesinyibilikisi sokugquma. Inokuba sisixhobo esiphakathi kwezibulali-zinambuzane okanye ixutywe nezinye ii-hydrocarbons ezingamanzi njengesinyibilikisi sokugquma.
