| Chemical Properties |
Dicyclopentadiene (DCPC) yog dimer ntawm cyclopentadiene. Thawj qhov cua sov yog siv los copolymerize cyclopentadiene rau hauv dicyclopentadiene, dicyclopentadiene yog cais los ntawm lwm yam teeb pom kev zoo (qhov kub kub.<45°C) by distillation, and then other required dienes, monocyclopentadiene are separated by solvent extraction. Alkene and saturated hydrocarbon components. High-purity dicyclopentadiene is a colorless crystal at room temperature. When it contains impurities, it is a light yellow oily liquid with a pungent camphor smell. It is insoluble in water and soluble in organic solvents such as alcohol and ether.
cyclopentadiene, txawm hais tias ib tug ruaj khov molecule, muaj ib tug muaj zog nyiam mus tsim lub ntau ruaj khov dimer dicyclopentadiene. Qhov no dimerisation twb tshwm sim nyob rau hauv chav tsev kub thiab nws tus nqi nce sai heev nrog siab kub. Cov tshuaj tiv thaiv no txawm li cas los xij yog thim rov qab ib yam nkaus; dicyclopentadiene "kawg" ntawm qhov kub siab tshaj 140 degree los tsim ob lub cyclopentadiene molecules. |
