Aromatics muab qee lub tsev hauv paus ntawm kev lag luam petrochemical niaj hnub. Cov khaub ncaws, ntim, pleev xim, nplaum nplaum, khoos phis tawj, cov discs, cov boards daus thiab ntaus pob tesniv yog cov khoom lag luam uas vam khom rau aromatics.
Dab tsi yog qhov tseem ceeb ntawm aromatics?
Aromaticity yog tseem ceeb vim nws ua rau cov molecules ruaj khov. Aromatic compounds ua lub luag haujlwm tseem ceeb hauv biochemistry thiab hauv kev lag luam. Amino acids yog lub tsev blocks ntawm cov proteins. Plaub ntawm lawv - histidine, phenylalanine, tyrosine, thiab tryptophan - yog aromatic.
Cov tshuaj tsw qab yog dab tsi thiab lawv siv rau dab tsi?
Aromatics yog hydrocarbons, cov organic tebchaw uas muaj tsuas yog cov ntsiab lus carbon thiab hydrogen - tsis muaj lub neej yuav tsis muaj nyob rau hauv lub ntiaj teb. Lub ntsiab aromatics yog benzene, toluene thiab xylenes; lawv tau siv ua cov ntaub ntawv pib rau ntau yam khoom siv
cov tshuaj tsw qab ua li cas?
Cov Khoom Ntawm Cov Khoom Uas Muaj Cov Khoom Uas Tsis Zoo Cov khoom sib xyaw no feem ntau tsis ua haujlwm thiab yog siv los ua cov kuab tshuaj rau ntau yam tsis muaj polar compounds
. Lawv cov pa roj carbon rau hydrogen piv yog siab, yog li ntawd, lawv muaj cov nplaim daj daj.
Qhov tseem ceeb ntawm cov pa roj carbon monoxide yog dab tsi?
Nyob rau hauv ntau qhov kev lag luam, cov tshuaj tsw qab hydrocarbons muaj kev siv dav. Piv txwv li, rau cov qauv kua nplaum, toluene yog siv los ua hnyavthaum naphthalene siv los ua mothballs. Rau kev tsim cov dyes, explosives, thiab tshuaj, Phenanthrene yog ib qho khoom nruab nrab uas muaj cov txheej txheem hluavtaws sib txawv.
