Kev Siv
Benzaldehyde yog siv ua ib qho nruab nrab hauv kev tsim cov tshuaj tsw qab, xws li cinnamaldehyde, cinnamal cawv, thiab amyl- thiab hexylcinnamaldehyde rau tshuaj tsw qab, xab npum, thiab cov khoom noj khoom haus; penicillin tsim, ampicillin, thiab ephedrine; thiab ua cov khoom siv raw rau tshuaj tua kab Avenge. Nws tshwm sim hauv xwm hauv cov noob ntawm almonds, apricots, cherries, thiab peaches. Nws tshwm sim hauv cov roj pob kws.
Kev tsim cov xim pleev, tshuaj tsw qab, cinnamic thiab mandelic acids, ua cov kuab tshuaj; hauv cov tsw qab.
Benzaldehyde yog ib yam khoom uas ua kua thiab tsis muaj xim, thiab muaj ntxhiab zoo li txiv almond. Nws muaj qhov saj kub (kub hnyiab). Nws raug oxidized rau benzoic acid thaum raug cua thiab lwj hauv qab lub teeb. Nws sib xyaw nrog cov roj volatile, cov roj ruaj khov, ether, thiab cawv; nws yaj me ntsis hauv dej. Nws tau los ntawm kev tsim tshuaj lom neeg thiab los ntawm kev tshwm sim ntuj hauv cov roj ntawm txiv almond iab, txiv duaj, thiab txiv duaj apricot. Nws kuj tseem hu ua benzoic aldehyde.
Ntim Khoom
200KG / Nruas los yog raws li cov neeg siv khoom xav tau.
Khaws cia thiab khaws cia
Lub neej txee: 24 lub hlis txij li hnub tsim khoom hauv cov ntim khoom tsis tau qhib khaws cia rau hauv qhov chaw txias thiab qhuav kom tsis txhob raug tshav ntuj ncaj qha, dej.
Lub tsev rau khoom muaj cua nkag, ziab kom qhuav kub tsawg, Sib cais ntawm cov tshuaj oxidants, cov kua qaub.
