Zoo:

1,2,3,4,5-Pentamethylcyclopentadiene yog cov kua tsis muaj xim uas muaj ntxhiab tsw tshwj xeeb. Nws yog tsawg ntom, insoluble nyob rau hauv dej, thiab soluble nyob rau hauv cov organic solvents.

Siv:

1,2,3,4,5-Pentamethylcyclopentadiene muaj ntau yam kev siv hauv kev lag luam chemistry. Nws tuaj yeem siv los ua cov khoom pib thiab nruab nrab hauv cov organic synthesis rau synthesis ntawm lwm cov organic tebchaw.

Txoj kev:

1,2,3,4,5-Pentamethylcyclopentadiene tuaj yeem ua ke los ntawm ntau txoj hauv kev. Cov txheej txheem kev npaj muaj xws li hauv qab no:

Cov tshuaj tiv thaiv los ntawm cyclopentene: cyclopentene thiab methylation reagents (xws li methyl bromide) yog siv los ua cov tshuaj alkaline los tsim 1-methylcyclopentene, thiab tom qab ntawd 1,2,3,4,5-pentamethylcyclopentadiene yog synthesized los ntawm cov tshuaj tiv thaiv methylation.

Ib qho carbon-carbon bond tsim cov tshuaj tiv thaiv catalyzed los ntawm cov hlau catalyst.

Cov ntaub ntawv kev nyab xeeb:

1,2,3,4,5-pentamethylcyclopentadiene muaj qee yam kev phom sij, thiab yuav tsum tau xyuam xim rau kev nyab xeeb thaum siv nws. Nov yog qee qhov kev pheej hmoo ntawm kev nyab xeeb:

Nws yog cov kua dej uas muaj hluav taws kub thiab yuav tsum tau khaws cia kom deb ntawm cov nplaim taws qhib thiab qhov chaw kub kub.

Tsis txhob nqus nws cov vapors, siv rau hauv qhov chaw uas muaj cua zoo, thiab siv cov cuab yeej tiv thaiv tus kheej tsim nyog (xws li kev tiv thaiv ua pa).

Nws tuaj yeem hnov ​​​​mob hnyav nrog cov tshuaj oxidizing muaj zog thiab muaj zog acids, ua rau hluav taws kub lossis tawg.

Thov ua haujlwm nrog ceev faj thaum siv thiab ua haujlwm raws li cov txheej txheem kev nyab xeeb uas cuam tshuam.
