Indene CAS 95-13-6
Indene, oo sidoo kale loo yaqaan benzocyclopropene, waa hydrocarbon udgoon polycyclic ah oo leh sunta hoose iyo xanaaqa maqaarka bini'aadamka iyo xuubabka xuubka. Waxay si dabiici ah ugu jirtaa daamurka dhuxusha iyo saliidda cayriin. Intaa waxaa dheer, indene ayaa sidoo kale la sii daayaa marka shidaalka macdanta aan si buuxda loo gubin. Qaaciddada molecular C9H8. Miisaanka molecular 116.16. Giraanta benzene iyo cyclopentadiene ee ku jira molecule-keeda waxay wadaagaan laba atamka kaarboon ee isku xiga. Waxa ay u muuqataa dareere aan midab lahayn, oo aan isbeddelayn uumiga, waxa uu isu beddelaa huruud marka uu istaago, laakiin waxa uu luminayaa midabka marka uu soo gaadho iftiinka qorraxda. Barta dhalaalka -1.8°C, barta karkarinta 182.6°C, barta toosh 58°C, cufnaanta qaraabo 0.9960 (25/4°C); aan lagu milmi karin biyaha, oo aan ku milmin ethanol ama ether. Unugyada Indene waxa ku jira curaarta olefin oo kimikal ahaan aad u firfircoon, kuwaas oo u nugul polymerization ama falcelinta dheeraadka ah. Indene waxay polymerize kartaa heerkulka qolka, kuleyliyaha ama joogitaanka kicinta aashitada waxay kordhin kartaa heerka polymerization si xoog leh, oo ay ula falgasho sulfuric acid oo uruursan si ay u sameyso resin secondary indene. Indene si toos ah ayaa hydrogenated (eeg falcelinta hydrogenation katalytic) si loo sameeyo dihydroindene. Kooxda methylene ee ku jirta molecule indene waxay la mid tahay kooxda methylene ee ku jirta cyclopentadiene molecule. Si fudud ayaa oksaydhaysan oo ay ula falgashaa baaruud si ay u soo saarto kakan, kaas oo leh fal-celin aashito ah oo daciif ah oo hoos u dhigta sifooyinka. Indene waxay la falgashaa sodium macdan si ay u samayso cusbo sodium, waxayna isku ururisaa aldehydes iyo ketones (eeg falcelinta uumiga) si ay u sameeyaan benzofulvene: Indene waxay ka soocday jajabka saliidda iftiinka ah ee laga helo qulqulka daamurka dhuxusha ee warshadaha.

Indene waxaa inta badan loo isticmaalaa in lagu soo saaro xabagta indene-coumarone. Walxaha ceeriin ee xabagta indene-coumarone waa 160-215 ° C jajab laga soo saaray benzene culus iyo jajabyada saliidda fudud, taas oo qiyaas ahaan ka kooban 6% styrene, 4% coumarone, 40% indene, 5% 4-methylstyrene iyo qadar yar oo ah xylene, toluene iyo xeryahooda kale. Wadarta xadiga resinka ayaa ah 60-70% alaabta ceeriin ee Buuga Kiimikada. Marka la eego ficilka kicinta sida aluminium chloride, boron fluoride ama sulfuric acid xoog leh, jajabyada indene iyo coumarone ayaa lagu sameeyaa cadaadis ama cadaadis la'aan si ay u dhaliyaan resin indene-coumarone. Waxa lagu qasi karaa hydrocarbons dareere ah sida dareere dahaarka ah. Waxa kale oo ay noqon kartaa dhexdhexaad ah sunta cayayaanka ama lagu qaso hydrocarbons kale dareere ah sida dareere daahan.
