Indene CAS 95-13-6

Indene, wanda aka fi sani da benzocyclopropene, wani sinadari ne mai kama da polycyclic aromatic hydrocarbon wanda ke da ƙarancin guba da kuma ƙaiƙayi ga fatar ɗan adam da membranes na mucous. Yana wanzuwa a zahiri a cikin kwal da man ɗanyen mai. Bugu da ƙari, indene yana fitowa lokacin da ba a ƙone man ma'adinai gaba ɗaya ba. Tsarin kwayoyin halitta C9H8. Nauyin kwayoyin halitta 116.16. Zoben benzene da cyclopentadiene a cikin kwayoyin halittarsa ​​suna raba ƙwayoyin carbon guda biyu da ke kusa. Yana bayyana a matsayin ruwa mara launi, baya canzawa a cikin tururi, yana zama rawaya lokacin da yake tsaye cak, amma yana rasa launi lokacin da aka fallasa shi ga hasken rana. Wurin narkewa -1.8°C, wurin tafasa 182.6°C, wurin walƙiya 58°C, yawan dangi 0.9960 (25/4°C); ba ya narkewa a cikin ruwa, ana iya mirgina shi da ethanol ko ether. Kwayoyin indene suna ɗauke da haɗin olefin masu aiki sosai a cikin sinadarai, waɗanda ke da saurin polymerization ko haɓakawa. Indene na iya yin polymer a zafin ɗaki, kuma dumamawa ko a gaban mai kara kuzari na acidic zai iya ƙara yawan polymerization sosai, kuma ya yi aiki da sinadarin sulfuric acid mai ƙarfi don samar da resin indene na biyu. Indene yana da hydrogenated ta hanyar catalytically (duba catalytic hydrogenation reaction) don samar da dihydroindene. Ƙungiyar methylene a cikin kwayar indene yayi kama da ƙungiyar methylene a cikin kwayar cyclopentadiene. Ana iya oxidize shi cikin sauƙi kuma yana amsawa da sulfur don samar da hadaddun abu, wanda ke da raunin amsawar acid da kuma rage kaddarorinsa. Indene yana amsawa da sodium na ƙarfe don samar da gishirin sodium, kuma yana haɗuwa da aldehydes da ketones (duba amsawar condensation) don samar da benzofulvene: Indene yana rabuwa da ƙaramin ɓangaren mai mai sauƙi da aka samu daga distillation na kwal tar a masana'antu.
