Propionic acid (CAS 79-09-4) puas yaj hauv dej?
Propanoic acid yog heev soluble nyob rau hauv polar solvents xws li dej, ethanol, thiab ether. Nyob rau hauv chav tsev kub, nws muaj peev xwm sib tov tag nrho nrog dej vim muaj nws cov carboxyl pawg, uas tsim hydrogen bonds nrog dej molecules.
Cov khoom ntawm propionic acid (CAS 79-09-4) yog dab tsi?
Dej soluble. Dilution nrog dej ua rau tso cua sov. Propionic acid yog cov xim tsis muaj xim, oily kua, nruab nrab toxic, corrosive. Flammable thaum raug tshav kub, nplaim taws lossis oxidizers.
