Lub Hwj Chim Muaj Peev Xwm hauv Cov Hluav Taws Xob
Cov tswv cuab ntawm tsev neeg aliphatic hydrocarbon, xws li methane, propane, thiab butane, yog qhov tseeb "cov khoom siv hluav taws xob." Methane, cov khoom tseem ceeb ntawm cov pa roj carbon monoxide, muab cov nplaim xiav rau suav tsis txheeb hauv tsev qhov cub, thaum cov roj av liquefied (propane / butane) ua rau camping barbecues nrog nws cov ntxhiab tsw ntxhiab. Tsis yog hais txog roj av thiab diesel, lub hauv paus tseem ceeb ntawm cov roj av, uas, tom qab ua kom zoo, muaj zog tshaj 90% ntawm lub ntiaj teb kev thauj mus los.
Versatile Building Blocks hauv Kev Tsim Tshuaj
Cov saw hlau hydrocarbon no muaj ntau yam zoo li Lego cib:
Cov Khoom Siv Yas: Ethylene polymerizes rau hauv hnab yas, propylene hloov mus rau hauv cov thawv ntim khoom noj
Synthetic Fibers: p-xylene yog ua tiav rau hauv cov khaub ncaws polyester
Solvent Helpers: n-Hexane yog ib tus khub zoo rau kev siv roj rho tawm
Cov khoom siv quav ciab: Ntev -chain alkanes kom ruaj khov hauv cov tswm ciab
Hidden Heroes hauv Lub Neej Txhua Hnub
Cov ntawv thov lom zem uas koj yuav tsis paub:
Ointment Base: Vaseline (C25-C40 alkanes) tiv thaiv cov tawv nqaij qhuav, tawg
Khoom noj khoom haus additives: Kua paraffin ua rau zom cov pos hniav ntau chewy thiab elastic
Cosmetic Carrier: Isododecane ua rau cov tshuaj pleev thaiv hnub ua kom zoo dua qub thiab tsis- nplaum
Cov tub yees nruab nrab: Isobutane dhau los ua kev xaiv tshiab rau cov tub yees zoo ib puag ncig
