Indene CAS 95-13-6

Indene, yomwe imadziwikanso kuti benzocyclopropene, ndi hydrocarbon ya polycyclic aromatic yokhala ndi poizoni wochepa komanso kuyabwa pang'ono pakhungu la anthu ndi mucous membranes. Imapezeka mwachilengedwe mu phula la malasha ndi mafuta osaphika. Kuphatikiza apo, indene imatulutsidwanso ngati mafuta amchere sanatenthedwe kwathunthu. Fomula ya molekyulu C9H8. Kulemera kwa molekyulu 116.16. Mphete ya benzene ndi cyclopentadiene mu molekyulu yake zimagawana maatomu awiri a kaboni oyandikana nawo. Imawoneka ngati madzi opanda mtundu, siisinthasintha mu nthunzi, imasanduka yachikasu ikaima, koma imataya mtundu ikakumana ndi dzuwa. Malo osungunuka -1.8°C, malo owira 182.6°C, malo owunikira 58°C, kuchuluka kwachibale 0.9960 (25/4°C); yosasungunuka m'madzi, yosakanizidwa ndi ethanol kapena ether. Mamolekyu a Indene ali ndi ma olefin bond omwe amagwira ntchito kwambiri, omwe amatha kupopera kapena kuwonjezera zochita. Indene imatha kupopera kutentha kwa chipinda, ndipo kutentha kapena kukhalapo kwa chothandizira cha asidi kumatha kuwonjezera kuchuluka kwa polymerization mwachangu, ndikuchitapo kanthu ndi sulfuric acid yokhazikika kuti ipange utomoni wachiwiri wa indene. Indene imapangidwa ndi hydrogenated (onani catalytic hydrogenation reaction) kuti ipange dihydroindene. Gulu la methylene mu molekyulu ya indene limafanana ndi gulu la methylene mu molekyulu ya cyclopentadiene. Imasungunuka mosavuta ndipo imachitapo kanthu ndi sulfure kuti ipange chovuta, chomwe chimakhala ndi acid reaction yofooka komanso mphamvu zochepetsera. Indene imakumana ndi sodium yachitsulo kuti ipange sodium salt, ndipo imasakanikirana ndi aldehydes ndi ketones (onani condensation reaction) kuti ipange benzofulvene: Indene imalekanitsidwa ndi gawo la mafuta owala lomwe limapezeka kuchokera ku distillation ya phula la malasha m'mafakitale.
