Indene CAS 95-13-6
Indene, tseem hu ua benzocyclopropene, yog polycyclic aromatic hydrocarbon uas tsis tshua muaj toxicity thiab irritation rau tib neeg daim tawv nqaij thiab mucous daim nyias nyias. Nws tshwm sim nyob rau hauv cov thee tar thiab crude roj. Tsis tas li ntawd, indene kuj tseem tso tawm thaum cov roj ntxhia tsis raug hlawv tag. Cov mis mos molecular C9H8. Molecular hnyav 116.16. Lub nplhaib benzene thiab cyclopentadiene nyob rau hauv nws cov molecule sib koom ob cov pa roj carbon atoms. Nws zoo nkaus 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, txheeb ze ntom ntom 0.9960 (25/4 ° C); insoluble nyob rau hauv dej, miscible nrog ethanol los yog ether. Indene molecules muaj cov tshuaj lom neeg muaj zog olefin bonds, uas yog feem ntau rau polymerization lossis ntxiv cov tshuaj tiv thaiv. Indene tuaj yeem ua polymerize ntawm chav tsev kub, thiab cua sov los yog nyob rau hauv lub xub ntiag ntawm ib tug acidic catalyst yuav ua rau kom lub polymerization tus nqi sharply, thiab react nrog concentrated sulfuric acid los ua ib tug thib ob indene resin. Indene yog catalytically hydrogenated (saib catalytic hydrogenation cov tshuaj tiv thaiv) los ua dihydroindene. Cov methylene pawg nyob rau hauv lub indene molecule zoo ib yam li cov methylene pawg nyob rau hauv lub cyclopentadiene molecule. Nws yog yooj yim oxidized thiab reacts nrog sulfur los tsim ib tug complex, uas muaj ib tug tsis muaj zog acid cov tshuaj tiv thaiv thiab txo cov khoom. Indene reacts nrog metallic sodium los tsim sodium ntsev, thiab condenses nrog aldehydes thiab ketones (saib condensation cov tshuaj tiv thaiv) los tsim benzofulvene: Indene yog cais los ntawm lub teeb roj feem uas tau los ntawm distillation ntawm thee tar hauv kev lag luam.
| Yam khoom | STANDARD | TSEEM CEEB |
| Qhov tshwm sim | Cov kua dej daj | Ua raws |
| Indene | > 96% | 97.69% |
| Benzonitrile tshuaj | <3% | 0.83% |
| Dej | <0.5% | 0.04% |
Indene feem ntau yog siv los tsim indene-coumarone resin. Cov khoom siv raw ntawm indene-coumarone resin yog 160-215 ° C feem distilled los ntawm hnyav benzene thiab lub teeb roj feem, uas kwv yees muaj 6% styrene, 4% coumarone, 40% indene, 5% 4-methylstyrene thiab ib qho me me ntawm xylene thiab lwm yam. Tag nrho cov nyiaj resin tso nyiaj rau 60-70% ntawm Chemicalbook raw khoom. Nyob rau hauv qhov kev txiav txim ntawm catalysts xws li txhuas chloride, boron fluoride los yog concentrated sulfuric acid, indene thiab coumarone fractions yog polymerized nyob rau hauv siab los yog tsis muaj siab los tsim indene-coumarone resin. Nws tuaj yeem sib xyaw nrog lwm cov kua hydrocarbons ua cov txheej txheem hnyav. Nws tuaj yeem yog qhov nruab nrab ntawm cov tshuaj tua kab lossis sib xyaw nrog lwm cov kua hydrocarbons ua cov txheej txheem hnyav.
