Khoom Description
Benzoic Acid (C6H5COOH) yog dab tsi?
Benzoic acidyog dav nyob rau hauv cov xwm nyob rau hauv daim ntawv ntawm dawb acids, esters, los yog lawv derivatives. Piv txwv li, nyob rau hauv cov pos hniav benzoin, nws muaj nyob rau hauv daim ntawv ntawm dawb acids thiab benzyl esters; Nws muaj nyob rau hauv daim ntawv dawb nyob rau hauv nplooj thiab qia bark ntawm ib co nroj tsuag; Nws muaj nyob rau hauv daim ntawv ntawm methyl ester los yog benzyl ester nyob rau hauv cov roj yam tseem ceeb; Nws muaj nyob rau hauv daim ntawv ntawm nws derivative hippuric acid nyob rau hauv nees zis. Benzoic acid yog cov kua qaub tsis muaj zog, muaj zog dua cov roj ntsha. Lawv muaj cov tshuaj zoo sib xws thiab tuaj yeem tsim cov ntsev, esters, acyl halides, amides, thiab anhydrides, tag nrho cov uas tsis yooj yim oxidized.
