Taw qhia
Furoyl acetate, tseem hu ua acetylsalicylate, yog cov organic compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm furfuryl acetate:
Zoo:
Furfuryl acetate yog cov xim tsis muaj xim rau daj daj daj nrog cov aroma tshwj xeeb. Nws yog soluble nyob rau hauv ntau yam organic solvents, xws li cawv thiab ethers, nyob rau hauv chav tsev kub.
Kev Siv: Nws muaj cov txiv hmab txiv ntoo uas muaj ntxhiab tsw thiab feem ntau siv hauv flavorings thiab spices kom muaj aroma thiab saj ntawm cov khoom. Furfur acetate tuaj yeem siv rau hauv kev lag luam xws li txheej, yas thiab roj hmab.
Txoj kev:
Furfur acetate feem ntau yog npaj los ntawm esterification cov tshuaj tiv thaiv, kev ua haujlwm tshwj xeeb yog ua rau cov tshuaj furfuric acid nrog acetic anhydride, ntxiv esterification catalysts xws li sulfuric acid lossis ammonium formate, thiab hnov mob ntawm qee qhov kub thiab sijhawm. Thaum kawg ntawm cov tshuaj tiv thaiv, impurities raug tshem tawm los ntawm lub cev qhuav dej thiab distillation kom tau cov ntshiab furfuryl acetate.
Cov ntaub ntawv kev nyab xeeb:
Furfuryl acetate muaj toxicity tsawg, tab sis kev nqus tau mus ntev yuav muaj kev cuam tshuam rau kev noj qab haus huv. Furfur acetate yog cov kua ua kua thiab yuav tsum tau khaws cia kom deb ntawm cov nplaim taws thiab qhov chaw kub, thiab khaws cia rau hauv qhov chaw txias, qhov cua. Ua tib zoo saib xyuas kev tiv thaiv thaum siv, xws li hnav tsom iav tiv thaiv, hnab looj tes tiv thaiv thiab khaub ncaws tiv thaiv. Nyob rau hauv cov ntaub ntawv ntawm spillage los yog lom, ua raws li qhov tsim nyog ntsuas kev pab tam sim ntawd thiab nrhiav kev kho mob raws sij hawm.
