Tshuaj mis ntawm cov tub yees r1270 propylene, c₃h₆, qhia tias nws yog muaj ntawm peb carbon atoms thiab rau hydrogen atoms. Nyob rau hauv cov qauv txheej txheem ntawm propylene, ib qho carbon atom ua ib daim ntawv sib dhos ib zaug, thaum lwm tus kab mob piide txuas nrog los ntawm cov roj carbon-carbon ob chav. Cov qauv txheej txheem no ua rau cov pa roj atoms hauv cov propylene molecule muaj qhov kev tsis muaj peev xwm ntau yam ntxiv li cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv polymerization. Txawm hais tias Propylene thiab cyclopropane muaj cov mis nyuj tib, lawv yog khub ntawm cov vaj tse yog vim muaj kev sib txuas atoms.
Tub yees R1270 propylene yog qhov tsis muaj kob, tsw ntxhiab, cov roj qab me ntsis ntawm chav sov thiab siab. Nws qhov ntom ntom yog ib nyuag loj dua li ntawm huab cua, ntawm 1.914G \/ l (hauv qab cov qauv). Lub ntsiab lus melting ntawm propylene yog -185 degree thiab qhov cub npau npau yog {}}. 68 degree. Nws yog insoluble hauv dej, tab sis yooj yim soluble hauv cov kuab tshuaj muaj zog xws li ethanol thiab ether. Cov khoom siv lub cev ua kom muaj kev sib txawv hauv cov txheej txheem sib txawv.
Tub yees r1270 cov tshuaj lom neeg ntawm propylene, thiab nws yooj yim rau cov tshuaj lom neeg xws li cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv polymerization. Txij li thaum propylene molecule muaj cov pa roj carbon-carbon ob daim ntawv cog lus, nws yog ib qho yooj yim rau yauv kom paub cov kev xav ntxiv. Piv txwv li, propylene tuaj yeem hnov mob nrog cov hydrogen los ua propane, thiab hnov nrog bromine dej los ua 1, {{} Dubromopropanane. Tsis tas li ntawd, Propylene tuaj yeem tuaj yeem yauv polymerization los ua polypropylene. Raws li kev txiav txim ntawm cov catalyst, ntau tus propylene molecules tau txuas nrog ua cov polymer compound polypropylene, uas yog ib qho khoom siv yas tseem ceeb.
Raws li ib qho tseem ceeb organic compound, propylene yog dav siv hauv kev lag luam, kev ua liaj ua teb, tshuaj thiab kev tshawb fawb. Hauv kev lag luam, propylene yog cov khoom siv tseem ceeb rau kev tsim cov tshuaj xws li cov polypropylene, acrylic acid, methyl acrylate, thiab roj hmab sis roj hmab. Cov tshuaj no tau siv dav hauv cov plastics, cov khoom siv hluavtaws, cov tshuaj, cov tshuaj txhua hnub, xim pleev xim, pleev xim rau lwm thaj chaw. Hauv kev ua liaj ua teb Hauv cov tshuaj, propylene tuaj yeem siv los tsim cov tshuaj, khoom siv kho mob, thiab yog siv dav hauv cov khoom siv kho mob, kev kho mob thiab lwm thaj chaw. Tsis tas li ntawd, Propylene tseem tuaj yeem siv los ua cov iav kws kos duab, kos duab kos duab, thiab lwm yam kev zoo nkauj rau tib neeg lub neej.
Hauv cov ntsiab lus, propylene, raws li ib qho tseem ceeb organic compound, nws cov mis nyuj colh₆ qhia nws cov yam ntxwv tshwj xeeb cov qauv tshuaj. Cov khoom siv lub cev, tshuaj lom neeg thiab ntau ntawm cov kev siv ntawm propylene ua rau nws ua lub luag haujlwm tsis tseem ceeb hauv ntiaj teb niaj hnub. Nrog rau kev kawm tob ntawm nws cov khoom thiab siv, cov kev thov kev cia siab ntawm propylene yuav dav.
