N-Pentane, o se fua fa'a kemikolo C ₅ H ₁₂ , o le vaega lona lima o le alkane. O le N-pentane e lua isomers: isopentane (mea faʻafefe 28 ° C) ma neopentane (mea faʻafefe 10 ° C), o le faaupuga "pentane" e masani ona faasino i le n-pentane, lona isomer linear.
Fa'aaogaina o le pentane masani
1. O loʻo faʻaaogaina e avea o se mea e faʻafefe ai le vai, o se mea faʻapalapala palasitika fale gaosi oloa, ma o loʻo faʻaaogaina faʻatasi ma le 2-methylbutane e fai ma fafie mo taavale ma vaalele, mo le gaosiga o le aisa faufau, se faʻamaʻi, mo le synthesizing pentanol, isopentane, ma mea faapena.
2. Fa'ata'ita'iga o su'esu'ega chromatographic kasa. Faʻaaogaina e avea o se faʻamaʻi, solvent, thermometer cryogenic, ma mo le gaosiga o le aisa faʻapitoa, pentanol, isopentane, ma isi.
3. Mo le sauniuniga o kasa masani, calibration kasa ma o se molecular sieve desorbent.
4. Fa'aaogaina e fai ma vaisu, kesi chromatography reference solution ma fa'ama'i. Faʻaaogaina foi i le faʻaogaina o meaola ma le gaosiga o thermometers cryogenic.
5. Faʻaaogaina e fai ma solu e fai ai le aisa faʻapitoa, faʻamaʻi, ma faʻapipiʻi pentanol, isopentane, ma isi mea faapena.
