Indene, wanda kuma aka sani da benzocyclopropene, shine polycyclic aromatic hydrocarbon tare da ƙarancin guba da haushi ga fatar ɗan adam da mucous membranes. Yana wanzuwa ta halitta a cikin kwalta kwal da ɗanyen mai. Bugu da ƙari, ana kuma saki indene lokacin da makamashin ma'adinai ba a ƙone gaba ɗaya ba. Tsarin kwayoyin halitta C9H8. Nauyin kwayoyin 116.16. Zoben benzene da cyclopentadiene a cikin kwayoyin halittarsa suna raba nau'ikan atom guda biyu na kusa da juna. Yana bayyana a matsayin ruwa mara launi, baya juyewa cikin tururi, yana juya rawaya idan ya tsaya cak, amma ya rasa launi lokacin fallasa hasken rana. Matsayin narkewa -1.8°C, wurin tafasa 182.6°C, madaidaicin walƙiya 58°C, ƙarancin dangi 0.9960 (25/4°C); insoluble a cikin ruwa, miscible tare da ethanol ko ether. Kwayoyin indene sun ƙunshi nau'ikan olefin masu aiki sosai, waɗanda ke da yuwuwar yin polymerization ko ƙarin halayen. Indene na iya yin polymerize a cikin zafin jiki, kuma dumama ko a gaban mai kara kuzari na acidic na iya ƙara yawan adadin polymerization da ƙarfi, kuma yana amsawa tare da sulfuric acid mai tattarawa don samar da resin indene na biyu. Indene yana da sinadarin hydrogenated (duba catalytic hydrogenation reaction) don samar da dihydroindene. Ƙungiyar methylene a cikin kwayoyin indene yayi kama da ƙungiyar methylene a cikin kwayoyin cyclopentadiene. Yana da sauƙin oxidized kuma yana amsawa tare da sulfur don samar da hadaddun, wanda ke da raunin acid mai rauni da rage kaddarorin. Indene yana amsawa tare da sodium na ƙarfe don samar da gishiri na sodium, kuma yana haɗuwa tare da aldehydes da ketones (duba amsawar iska) don samar da benzofulvene: Indene ya rabu da ɓangaren mai mai haske da aka samu daga distillation na kwalta a masana'antu.

Ana amfani da Indene galibi don samar da resin indene-coumarone. Danyen abu na indene-coumarone resin shine 160-215 ° C da aka distilled daga nauyi benzene da man mai haske, wanda kusan ya ƙunshi 6% styrene, 4% coumarone, 40% indene, 5% 4-methylstyrene da ƙaramin adadin xylene, toluene da sauran mahadi. Jimlar adadin guduro yana da kashi 60-70% na albarkatun albarkatun Littafin. Karkashin aikin masu kara kuzari kamar aluminum chloride, boron fluoride ko sulfuric acid mai mai da hankali, indene da coumarone ɓangarorin suna polymerized ƙarƙashin matsin lamba ko ba tare da matsa lamba don samar da resin indene-coumarone ba. Ana iya haɗa shi da sauran ruwa hydrocarbons a matsayin kaushi mai rufi. Hakanan yana iya zama tsaka-tsaki na magungunan kashe qwari ko gauraye da sauran ruwa hydrocarbons a matsayin kaushi mai rufi.
