Kev siv propionic acid yog dab tsi?
propanoic acid Cov ntawv thov:
Ua haujlwm ua cov khoom siv raw hauv cov organic synthesis, feem ntau yog rau kev tsim cov ntsev propionate thiab esters. Nws Calcium thiab cov ntsev sodium yog cov tshuaj preservatives zoo heev uas siv rau hauv cov khoom ci thiab cov khoom noj txom ncauj. Nws cov esters tuaj yeem siv ua cov tshuaj tsw qab thiab cov tshuaj yaj tshwj xeeb rau cov txheej. Phenylmercuric propionate yog cov tshuaj tua kab mob zoo rau cov xim. Propionic acid kuj tseem siv ua cov khoom ntxiv rau hauv silage.
Propanoic acid Ntim:
Cov kua qaub propionic uas muaj qhov huv siab tshaj 99.5% yuav tsum tau ntim rau hauv cov thawv uas ua los ntawm hlau lossis txhuas. Cov kua qaub propionic uas yaj lawm yuav tsum tsis txhob khaws cia rau hauv cov thoob txhuas; cov thoob uas ua los ntawm hlau lossis hlau uas muaj yas npog yog qhov tsim nyog.
Kev Lom thiab Kev Nyab Xeeb:
Propionic acid yog ib yam kua uas yooj yim hlawv thiab tsis muaj tshuaj lom. Nws tuaj yeem ua rau khaus thiab tua cov kab mob. Yog tias raug daim tawv nqaij, yaug kom huv si nrog dej ntau. Qhov concentration siab tshaj plaws hauv huab cua yog 150 mg/m³.
