Indene CAS 95-13-6
Indene, yomwe imadziwikanso kuti benzocyclopropene, ndi polycyclic onunkhira hydrocarbon yokhala ndi kawopsedwe kakang'ono komanso kusakwiya pakhungu ndi mucous nembanemba. Zimapezeka mwachilengedwe mu phula la malasha ndi mafuta osapsa. Kuphatikiza apo, inde imatulutsidwanso pamene mafuta amchere samatenthedwa kwathunthu. Molecular formula C9H8. Kulemera kwa molekyulu 116.16. Mphete ya benzene ndi cyclopentadiene mu molekyulu yake amagawana maatomu awiri oyandikana nawo. Zimawoneka ngati zamadzimadzi zopanda mtundu, sizimasungunuka mu nthunzi, zimasanduka zachikasu zikaima, koma zimataya mtundu zikakhala padzuwa. Kusungunuka -1.8 ° C, kuwira 182.6 ° C, kung'anima 58 ° C, kachulukidwe wachibale 0.9960 (25/4 ° C); osasungunuka m'madzi, osakanikirana ndi ethanol kapena ether. Mamolekyu a Indene amakhala ndi ma olefin omwe amagwira ntchito kwambiri ndi mankhwala, omwe amakonda kuchitapo kanthu kapena kuchitapo kanthu. Indene akhoza polymerize firiji, ndi Kutentha kapena pamaso pa chothandizira acidic akhoza kuonjezera polymerization mlingo kwambiri, ndi anachita ndi anaikira sulfuric asidi kupanga yachiwiri inde utomoni. Indene ndi catalytically hydrogenated (onani catalytic hydrogenation reaction) kupanga dihydroindene. Gulu la methylene mu molekyulu ya Indene ndi lofanana ndi gulu la methylene mu molekyulu ya cyclopentadiene. Imakhala ndi okosijeni mosavuta ndipo imakhudzidwa ndi sulfure kuti ipange zovuta, zomwe zimakhala ndi asidi ofooka komanso kuchepetsa katundu. Indene imachita ndi metallic sodium kupanga mchere wa sodium, ndipo imalumikizana ndi aldehydes ndi ketones (onani condensation reaction) kupanga benzofulvene: Indene imasiyanitsidwa ndi kagawo kakang'ono ka mafuta opepuka omwe amachokera ku distillation ya malasha phula mumakampani.

Indene imagwiritsidwa ntchito makamaka popanga utomoni wa indene-coumarone. Zopangira za indene-coumarone resin ndi 160-215 ° C kachigawo kakang'ono kamene kamasungunuka kuchokera ku heavy benzene ndi mafuta ochepa, omwe amakhala ndi 6% styrene, 4% coumarone, 40% indene, 5% 4-methylstyrene ndi pang'ono xylene, toluene ndi mankhwala ena. Chiwerengero chonse cha utomoni ndi 60-70% ya Chemicalbook zopangira. Pansi pa zochita za catalysts monga zotayidwa kolorayidi, boron fluoride kapena anaikira sulfuric asidi, Indene ndi coumarone tizigawo ting'onoting'ono ndi polymerized pansi mavuto kapena popanda kukakamizidwa kupanga indene-coumarone utomoni. Itha kusakanikirana ndi ma hydrocarbons ena amadzimadzi ngati chosungunulira chopaka. Itha kukhalanso mankhwala ophera tizilombo kapena osakanikirana ndi ma hydrocarbon ena amadzimadzi ngati chosungunulira.
