Propionic acid yog dab tsi?
propanoic acid Cov Ntaub Ntawv Tseem Ceeb
Propanoic acid, tseem hu ua propionic acid, yog cov roj fatty acid luv luv nrog cov tshuaj formula CH₃CH₂COOH thiab qhov hnyav molecular ntawm 74.08. Ua ib qho electrolyte tsis muaj zog (Ka = 1.34 × 10⁻⁵), propanoic acid muaj cov kua qaub tsis muaj zog hauv cov kua dej tab sis nws muaj zog heev. Nws cov pa tuaj yeem ua rau khaus tawv nqaij thiab txoj hlab pa. Hauv qab qhov kub thiab txias thiab siab, propanoic acid yog cov kua tsis muaj xim, ntshiab, roj nrog cov ntxhiab tsw qab, ntxhiab tsw phem. Nws sib xyaw nrog dej, ethanol, chloroform, thiab ether.
Propanoic acid feem ntau yog siv ua cov tshuaj khaws cia zaub mov thiab cov tshuaj tua kab mob fungal. Nws kuj tseem ua haujlwm ua tus inhibitor ntawm cov khoom viscous hauv cov dej haus xws li npias, ua cov kuab tshuaj thiab cov yas rau nitrocellulose, thiab hauv kev npaj cov tshuaj nickel-plating, cov khoom noj khoom haus, tshuaj, tshuaj tua kab mob, cov tshuaj tua kab mob fungal, thiab lwm yam khoom lag luam.
Propanoic acid tau teev nyob rau hauv Daim Ntawv Teev Cov Tshuaj Lom Zem thiab raug tswj hwm raws li Cov Cai ntawm Kev Tswj Xyuas Kev Nyab Xeeb ntawm Cov Tshuaj Lom Zem.
