Kev Siv
Cyclopentane yog ib hom hydrocarbon cyclic uas muaj qhov kub tsawg thiab tsis ua rau ib puag ncig puas tsuaj, siv dav hauv kev lag luam. Nws cov kev siv tseem ceeb yog raws li nram no:
1. **Tshuaj Txias & Tshuaj Ua Pa** Nws hloov cov tshuaj uas ua rau lub ozone puas tsuaj (xws li CFCs) los ua cov ua npuas rwb thaiv tsev rau lub tub yees, lub tub yees khov, thiab phab ntsa tsev. Nws kuj ua haujlwm ua tshuaj txias hauv cov tshuab kub qis (piv txwv li, kev khaws cia txias hauv kev lag luam) vim tsis muaj kev pheej hmoo ntawm kev puas tsuaj rau ozone.
2. **Cov Khoom Siv Ua Los Ntawm Organic Synthesis** Nws siv los tsim cyclopentanol (rau cov resins/txheej txheej) thiab cyclopentanone (rau cov tshuaj, cov tshuaj tua kab) los ntawm kev oxidation. Nws kuj pab ua cov polymers ua tau zoo rau cov tsheb thiab cov khoom siv hluav taws xob.
3. **Cov kuab tshuaj** Nws ntxuav cov khoom hlau (piv txwv li, cov khoom siv hluav taws xob) los ntawm kev yaj cov roj, thiab siv rau hauv chav kuaj kom rho tawm cov tshuaj uas tsis yog polar lossis ua cov tshuaj tiv thaiv kub qis.
4. **Tshuaj Ntxiv Roj** Sib xyaw rau hauv roj av/roj dav hlau kom nce tus lej octane (txhim kho kev ua haujlwm ntawm lub cav tiv thaiv kev sib tsoo). Nws kuj tseem tuaj yeem yog roj ntxiv rau cov khoom siv me me xws li cov qhov cub pw hav zoov.
5. **Lwm Yam Kev Siv** Nws calibrates cov cuab yeej siv hauv chav kuaj (piv txwv li, roj chromatographs) thiab ua haujlwm ua tus qauv sib xyaw hauv kev tshawb fawb txog hydrocarbon chemistry.
Ntim thiab Xa Khoom
Nruas / ISOTANK los yog raws li cov neeg siv khoom xav tau.
Yog cov khoom siv dav dav thiab tuaj yeem xa los ntawm dej hiav txwv
Khaws cia thiab khaws cia
Lub neej txee: 24 lub hlis txij li hnub tsim khoom hauv cov ntim khoom tsis tau qhib khaws cia rau hauv qhov chaw txias thiab qhuav kom tsis txhob raug tshav ntuj ncaj qha, dej.
Lub tsev rau khoom muaj cua nkag, ziab kom qhuav kub tsawg, Sib cais ntawm cov tshuaj oxidants, cov kua qaub.
