Zoo heev Chemical Stability
Alkane molecules tsuas muaj cov pa roj carbon ruaj khov -carbon thiab carbon- hydrogen ib daim ntawv cog lus. Raws li cov txheej txheem, lawv tsis hnov mob nrog cov kua qaub, muaj zog hauv paus, lossis muaj zog oxidants (xws li acidic potassium permanganate); Lawv yog cov resistant rau degradation thiab tsis corrode substrates. Thaum siv los ua cov khoom noj khoom haus lossis cov kuab tshuaj, lawv txo qis qhov kev pheej hmoo ntawm kev cuam tshuam sab nraud thaum lub sijhawm tsim khoom thiab xyuas kom cov batch- rau- cov khoom sib xws hauv cov khoom lag luam qis, ua rau lawv tsim nyog rau cov ntawv thov uas xav tau kev tswj hwm tsis huv, xws li cov tshuaj intermediates thiab precision electronics tu. Qee cov khoom siab tshaj -purity isoalkane cov khoom muaj cov ntsiab lus uas muaj ntxhiab tsawg dua 0.1% thiab tsis muaj kev puas tsuaj rau impurities, tswj lawv cov kev ua tau zoo txawm tias lub sijhawm ntev - khaws cia.
Favorable combustion yam ntxwv
Raws li saturated hydrocarbons, alkanes muaj cov pa roj carbon tshwj xeeb - rau -hydrogen piv uas tso cai rau ua tiav oxidation thaum lub sij hawm combustion. Lawv tsim cov xim xiav xiav, zoo li nplaim taws tsis muaj pa taws, nrog cov pa roj carbon dioxide thiab dej ua cov khoom siv hluav taws xob ua kom tiav, thaum tib lub sijhawm tso tawm ntau lub zog thermal. Piv rau unsaturated hydrocarbons zoo li alkenes, lawv tsis tshua muaj peev xwm tsim cov pa luam yeeb dub, carbon monoxide, lossis lwm yam khoom ntawm kev sib txuas tsis tiav. Yog li ntawd, lawv muab cov thermal efficiency ntau dua thiab qis dua cov pa paug thaum siv roj, ua cov khoom siv tseem ceeb hauv pej xeem thiab kev lag luam roj xws li roj av, roj av, thiab diesel.
Cov yam ntxwv zoo ib puag ncig thiab kev nyab xeeb
Mainstream alkane feedstocks tuaj yeem tsim ua kom muaj ntxhiab tsw thiab qis - lossis txawm xoom -VOC (Volatile Organic Compound) cov ntsiab lus. Lawv tuav ntau daim ntawv pov thawj thoob ntiaj teb ib puag ncig, xws li REACH thiab SGS, ua kom muaj kev ua raws li cov cai nruj tshaj tawm ntawm EU thiab North America thiab tiv thaiv kev nplua lossis kev txeeb khoom vim ib puag ncig tsis ua raws -. Tsis tas li ntawd, lawv cov ntsiab lus flash yog tswj tau, thiab cov evaporation tuaj yeem hloov kho kom haum rau cov xwm txheej tshwj xeeb; Qhov no txhim kho qhov chaw ua haujlwm hauv chaw ua haujlwm thiab tshem tawm kev nyab xeeb kev nyab xeeb cuam tshuam nrog cov nplaim taws thiab pungent tsw ntawm cov kuab tshuaj ib txwm muaj, yog li ua raws li cov qauv kev nyab xeeb niaj hnub no.
