Kev lag luam glyoxal yog npaj los ntawm gas-theem oxidation ntawm ethylene glycol hauv muaj cov nyiaj lossis tooj liab catalyst (cov txheej txheem Laporte) lossis los ntawm cov kua theem oxidation ntawm acetaldehyde nrog nitric acid.
Koj yuav npaj glyoxal los ntawm benzene li cas?
Benzene tuaj yeem hloov mus rau glyoxal los ntawm txheej txheem ntawm txo OzonolysisBenzene thawj zaug nrog ozone tsim ozonide. Qhov no ozonide dhau los ua cov txheej txheem ntawm hydrolysis nyob rau hauv lub xub ntiag ntawm zinc rau muab glyoxal. Zinc yog siv rau hauv cov txheej txheem no los xyuas kom meej tias oxidation ntawm aldehydes rau hauv acids tsis tshwm sim.
glyoxal tsw zoo li cas?
Glyoxal zoo li daj crystals melting ntawm 15 ° C. Li no feem ntau ntsib raws li cov kua daj daj nrog a qaug qaub tsw. Vapor muaj xim ntsuab thiab kub hnyiab nrog nplaim violet.
YPuas glyoxal dej soluble?
Glyoxal yog soluble (hauv dej) thiab ib qho yooj yim tsis muaj zog (qhov tseem ceeb nruab nrab) compound (raws li nws pKa).
Qhov txawv ntawm glycol thiab glyoxal yog dab tsi?
Kev piav qhia: Glyoxal yog dialdehyde, H(O=)C−C(=O)H … uas feem ntau yog siv los ua cov khoom ua ntej rau cov organic synthesis… Ntawm qhov tod tes, glycol yog a dialcohol… … ntawm no cov carbon oxidation xeev yog −I, whereas nyob rau hauv glyoxal lub carbon oxidation xeev yog +I.
