| Kev siv Norbornene thiab Synthesis |
| Chemical Properties | dawb crystalline loj |
| Siv | Norbornene yog siv los ua monomer thiab ua ib qho nruab nrab hauv cov organic synthesis. Nws kuj yog siv los npaj cov tshuaj intermediates thiab cov tshuaj tsw qab tshwj xeeb. Nws reacts nrog ethylene kom tau txais cyclic olefin copolymer. Tsis tas li ntawd, nws yog siv rau hauv kev hloov pauv hlau catalysis los cuam tshuam kev tsiv teb tsaws ntawm electrophilic hloov hlau. Nws ua raws li ib tug monomer nyob rau hauv lub nplhaib-qhib metathesis polymerizations nrog cov Grubbs 'catalyst. Nws cov polymer, polynorbornene yog siv rau hauv kev lag luam roj hmab rau kev tiv thaiv kev vibration, tiv thaiv kev cuam tshuam hauv cov khoom siv tiv thaiv tus kheej thiab kev txhim kho tuav hauv cov khoom ua si, cov log tsheb sib tw thiab kev sib kis. |
| Txhais | ChEBI: Norbornene yog ib qho txuas txuas uas yog cyclohexane nrog tus choj methylene ntawm carbons 1 thiab 4 thiab ob daim ntawv cog lus ntawm txoj hauj lwm 2. Nws yog ib qho txuas txuas, carbobicyclic compound thiab cyclic olefin. |
| Kev piav qhia dav dav | Vinylic polymerization ntawm bicyclo[2.2.1]hept-2-ene (norbornene) nrog Co(II) compounds thiab metallocene [η5-(C5Kuv5) cov2-Cl]2, hauv chlorobenzene qhib nrog methylaluminoxane (MAO) tau tshaj tawm. Co(II) catalyzed polymerization ntawm bicyclo[2.2.1]hept-2-ene nyob rau hauv lub xub ntiag ntawm ethene tau raug tshaj tawm. |
| Flammability thiab Explosibility | Tsis yog nplaim taws |
| Txoj kev Purification | Reflux nws hla Na, thiab distil nws [Gilliom & Grubbs J Am Chem Soc 108 733 1986]. Nws kuj tau raug purified los ntawm sublimation nyob rau hauv vacuo mus rau ib tug ice txias ntiv tes. [Woon et al. J Am Chem Soc 108 7990 1986, Beilstein 5 IV 394.] |
