Kev sib txheeb ntawm aldehyde thiab ketones nrog para Anisidine yog dab tsi?
p-Anisidine condenses nkag nrog aldehydes thiab ketones los ua Schiff bases, uas nqus ntawm 350 nm. Cov tshuaj tiv thaiv colorimetric no yog siv los ntsuas qhov muaj cov khoom oxidation hauv cov rog thiab roj, ib txoj hauv kev los kuaj xyuas lawv los ntawm American Oil Chemists' Society.
P-Anisidine tus nqi yog dab tsi?
Para-anisidine yog ib qho reagent uas cuam tshuam nrog aldehydes muab cov khoom uas nqus ntawm 350 nm (Fig.7.5). Tus nqi p-anisidine txhais tau tias yog nqus ntawm cov tshuaj uas tshwm sim los ntawm cov tshuaj tiv thaiv ntawm 1g rog hauv isooctane tov(100 ml) nrog p-anisidine (0.25% hauv glacial acetic acid).
Txoj kev rancimat yog dab tsi?
Cov txheej txheem Rancimat yog kev ntsuas kev laus nrawm Cua yog dhau los ntawm cov qauv hauv cov tshuaj tiv thaiv cov hlab ntsha ntawm qhov kub thiab txias tsis tu ncua thiab cov roj fatty acids tau oxidized hauv cov txheej txheem no. … Vim yog qhov nqus ntawm cov khoom siv tshuaj tiv thaiv, qhov tsis tu ncua kaw hluav taws xob conductivity ntawm cov tshuaj ntsuas loj hlob.
