Pentanlar, S5N|2 \u2014 to’yingan ug-levodorodlar. Mol. m. 72,146. Uchta izo-meri bor: normal pentan SN3(SN2)3 SN3 (“\u2014P.), izopentan (SN3)2SNSN2 SN3 (2-metilbutan) va neopentan (SN3)4S (2,2-dimetilpropan, tetrame- tilmetan). n-P. va izopentan \u2014 o’ziga xos hidli, rangsiz, yonuvchan suyukliklar, neopentan \u2014 gaz. n-P.ning suyuqlanish t-rasi \u2014 129,72\u00b0; qaynash t-rasi 36,07\u00b0; zichligi 626 kg\/m3. Izopentanning suyuqlanish t-rasi \u2014 159,89\u00b0; qaynash t-rasm 27,85\u00b0; zichligi 620 kg\/m3. Neo- pentanning suyuklanish t-rasi -16,55\u00b0; kaynash t-rasi 9,5\u00b0; zichligi 591 kg\/m3. P. gaz kondensatlari, neft, neftni qayta ishlash mah-sulotlari tarkibida bo’ladi va bu mah-sulotlardan rektifikasiya usuli b-n ajratib olinadi. Tabiiy gaz- dan oli-nadigan benzin tarkibidan 40% gacha texnik P. (“-P. va izopentan- ning 1:1 nisbatdagi aralashmasi hamda qo’shimcha sifatida 2% gacha neopentan) bo’ladi. n-P. izopeptan, pentenlar, amil spirtlar va ularning efirlari, amil- fenol va b. olishda, shuningdek, eri-TUV- chi sifatida ishlatiladi. Izopentan \u2014 yuqori oktanli benzinlar kom-ponenti. Texnik izopentan (zichligi 620 kg\/m3, motor usuli bo’yicha oktan soni 90) Ben- zinlarning oktan sonini oshirish va tetraetilqo’rg’oshin qo’llashni kamayti- rish maqsadida 15% gacha qo’shiladi.<\/p>\n","protected":false},"excerpt":{"rendered":"
