Indene CAS 95-13-6 yog dab tsi?

Indene, tseem hu ua benzocyclopropene, yog ib hom polycyclic aromatic hydrocarbon uas muaj tshuaj lom tsawg thiab ua rau khaus rau tib neeg daim tawv nqaij thiab cov qog ua kua. Nws muaj nyob rau hauv cov thee tar thiab cov roj nyoos. Tsis tas li ntawd, indene kuj raug tso tawm thaum cov roj av tsis tau hlawv tag. Cov mis molecular C9H8. Qhov hnyav molecular 116.16. Lub nplhaib benzene thiab cyclopentadiene hauv nws cov molecule sib koom ob lub carbon atoms sib ze. Nws zoo li cov kua tsis muaj xim, tsis volatilize hauv vapor, tig daj thaum sawv ntsug, tab sis poob xim thaum raug tshav ntuj. Melting point -1.8°C, boiling point 182.6°C, flash point 58°C, relative density 0.9960 (25/4°C); insoluble hauv dej, sib xyaw nrog ethanol lossis ether. Indene molecules muaj cov tshuaj olefin bonds uas muaj zog heev, uas yooj yim rau polymerization lossis ntxiv cov tshuaj tiv thaiv. Indene tuaj yeem polymerize ntawm chav tsev kub, thiab cua sov lossis nyob rau hauv qhov muaj cov tshuaj catalyst acidic tuaj yeem ua rau kom tus nqi polymerization nce siab, thiab react nrog concentrated sulfuric acid los tsim cov indene resin theem ob. Indene yog catalytic hydrogenated (saib catalytic hydrogenation reaction) los tsim dihydroindene. Pawg methylene hauv indene molecule zoo ib yam li pawg methylene hauv cyclopentadiene molecule. Nws yooj yim oxidized thiab reacts nrog sulfur los tsim ib qho complex, uas muaj cov tshuaj tiv thaiv acid tsis muaj zog thiab txo cov khoom. Indene reacts nrog metallic sodium los tsim sodium ntsev, thiab condenses nrog aldehydes thiab ketones (saib condensation reaction) los tsim benzofulvene: Indene yog sib cais los ntawm cov roj teeb tau los ntawm kev distillation ntawm thee tar hauv kev lag luam.

Daim Ntawv Thov

Indene feem ntau yog siv los tsim cov tshuaj indene-coumarone. Cov khoom siv raw ntawm indene-coumarone resin yog 160-215 ° C feem distilled los ntawm cov roj benzene hnyav thiab cov roj sib xyaw, uas kwv yees li muaj 6% styrene, 4% coumarone, 40% indene, 5% 4-methylstyrene thiab me me ntawm xylene, toluene thiab lwm yam sib xyaw. Tag nrho cov resin suav txog 60-70% ntawm cov ntaub ntawv raw Chemicalbook. Nyob rau hauv qhov kev ua ntawm cov catalysts xws li txhuas chloride, boron fluoride lossis concentrated sulfuric acid, indene thiab coumarone feem yog polymerized nyob rau hauv siab lossis tsis muaj siab los tsim cov tshuaj indene-coumarone. Nws tuaj yeem sib xyaw nrog lwm cov kua hydrocarbons ua cov tshuaj pleev xim. Nws kuj tuaj yeem yog cov tshuaj tua kab nruab nrab lossis sib xyaw nrog lwm cov kua hydrocarbons ua cov tshuaj pleev xim.
