Indene CAS 95-13-6
Indene, inozivikanwawo se benzocyclopropene, ndeye polycyclic inonhuhwirira hydrocarbon ine yakaderera muchetura uye kushatirwa kuganda remunhu uye mucous membranes. Inowanikwa mumarara emarasha nemafuta asina kuchena. Mukuwedzera, indene inosunungurwawo kana mineral fuels isina kupiswa zvachose. Molecular formula C9H8. Molecular uremu 116.16. Mhete yebenzene uye cyclopentadiene mumorekuru wayo anogovera maatomu ecarbon maviri ari pedyo. Inoratidzika semvura isina ruvara, haichinji mumhute, inoshanduka yero kana yakamira, asi inorasikirwa neruvara kana yakavhenekerwa nechiedza chezuva. Melting point -1.8°C, boiling point 182.6°C, flash point 58°C, relative density 0.9960 (25/4°C); isinganyungudika mumvura, yakasanganiswa ne ethanol kana ether. Indene mamorekuru ane akanyanya makemikari anoshanda olefin mabhondi, ayo anowanzo kuita polymerization kana kuwedzera maitiro. Indene inogona polymerize pakamuri tembiricha, uye kudziyisa kana pamberi peine acidic catalyst inogona kuwedzera chiyero chepolymerization zvakanyanya, uye kuita neyakaomeswa sulfuric acid kuumba yechipiri inde resin. Indene inonzi catalytically hydrogenated (ona catalytic hydrogenation reaction) kuumba dihydroindene. Boka re methylene mu inde molecule rakafanana neboka re methylene mu cyclopentadiene molecule. Iyo iri nyore oxidized uye inopindirana nesarufa kuti ibudise yakaoma, iyo ine isina simba acid reaction uye inoderedza maitiro. Indene inopindirana nesimbi yesodium kuti igadzire munyu wesodium, uye inobatana nealdehydes uye ketones (ona condensation reaction) kuti iite benzofulvene: Indene inoparadzaniswa kubva pachikamu chemafuta akareruka anowanikwa kubva pakunyungudutswa kwetara yemarasha muindasitiri.

Indene inonyanya kushandiswa kugadzira indene-coumarone resin. The raw material ye indene-coumarone resin ndiyo 160-215 ° C chikamu chakasvibiswa kubva kune heavy benzene uye light oil fractions, iyo inenge ine 6% styrene, 4% coumarone, 40% indene, 5% 4-methylstyrene uye shoma shoma yexylene, toluene nemamwe macompound. Huwandu hweresin hunoita 60-70% ye Chemicalbook raw materials. Pasi pechiito chezvinokonzeresa senge aruminiyamu chloride, boron fluoride kana concentrated sulfuric acid, indene uye coumarone zvikamu zvinoumbwa zvine polymer pasi pekumanikidzwa kana pasina kumanikidzwa kugadzira indene-coumarone resin. Inogona kusanganiswa nemamwe mahydrocarbon emvura sechinhu chinonyungudutsa. Inogona zvakare kuve yepakati yemishonga yezvipembenene kana yakasanganiswa nemamwe mahydrocarbon emvura sechinhu chinonyungudutsa.
