N-Pentane, mokhoa oa lik'hemik'hale C ₅ H ₁₂ , setho sa bohlano sa alkane. N-pentane e na le li-isomer tse peli: isopentane (ntlha e belang 28 ° C) le neopentane (ntlha e belang 10 ° C), lentsoe "pentane" hangata le bolela n-pentane, isomer ea eona e lekanang.
Tšebeliso ea pentane e tloaelehileng
1. E sebelisoa e le mokelikeli o tlaase oa ho bela, mochine oa polasetiki oa indasteri ea foaming, hape e sebelisoa hammoho le 2-methylbutane e le mafura a likoloi le lifofane, bakeng sa ho etsa leqhoa la maiketsetso, moriana o thethefatsang, bakeng sa synthesizing pentanol, isopentane, le joalo ka.
2. Litekanyetso tsa tlhahlobo ea chromatographic ea khase. E sebelisoa e le anesthetic, solvent, cryogenic thermometer, le bakeng sa ho etsa leqhoa la maiketsetso, pentanol, isopentane, joalo-joalo.
3. Bakeng sa ho lokisa khase e tloaelehileng, khase ea calibration le e le molecular sieve desorbent.
4. E sebelisoa e le solvent, khase chromatography reference solution le anesthetic. E boetse e sebelisoa ho organic synthesis le ha ho etsoa li-thermometers tsa cryogenic.
5. E sebelisoa e le solvent ho etsa leqhoa la maiketsetso, moriana o thethefatsang mathe, le synthesize pentanol, isopentane, joalo-joalo.
