Pentane vs. n-Pentane: Qhov txawv ntawm Lawv yog dab tsi
Pentaneyog lub npe dav dav rau txhua lub molecule nrog cov tshuaj formula C₅H₁₂.
n-Pentaneyog lub npe tshwj xeeb rau lubncaj- sawversion ntawm qhov molecule. Nws yog ib qho ntawm peb daim ntawv ("isomers") ntawm pentane.
| Feature | Pentane | n-Pentane (ib txwm Pentane) |
|---|---|---|
| Basic tswvyim | Ib lub sij hawm dav dav rau ib pab pawgpeb tus qauv isomersnrog tib cov qauv molecular C5H12. | A ib leeg, tshwj xeeb isomerntawm pentane; daim ntawv unbranched (linear) ntawm C5H12. |
| Isomer Composition | Xws li peb qhov sib txawv: 1. n-Pentane (txoj saw ncaj)2. Isopentane (2-methylbutane, ceg saw) 3. Neopentane (2,2-dimethylpropane, cov saw loj heev) | Tsuas yog tus ncaj- saw isomer: CH3CH2CH2CH2CH3 |
| CAS Nr | Tsis muaj tus lej CAS (nrog peb cov tshuaj sib txawv). | CAS Nr.:109-66-0 |

Pentanes thiab cov kuab tshuaj muaj feem xyuam yog cov nplaim taws heev. Cov cua sov yuav ua rau muaj kev nce siab nrog kev pheej hmoo ntawm tawg. Vapor / cua sib tov yog tawg. Khaws rau hauv cov thawv kaw kom nruj hauv qhov chaw txias, zoo - qhov cua. Pentanes yog incompatible nrog muaj zog oxidizers. Huab cua- muab lub tshuab ua pa raug pom zoo thaum tuav, vim tias pentanes yuav ua rau lub qhov muag, tawv nqaij, qhov ntswg, thiab lub ntsws. Isooctane yog nephrotoxin.
