Formic Acid

Formic Acid (HCOOH, CAS 64-18-6), tseem hu ua methanoic acid lossis "ant acid," yog cov carboxylic acid uas yooj yim tshaj plaws - tsis muaj xim, fuming kua nrog pungent tsw. Boiling ntawm 100.8℃thiab tag nrho miscible nrog dej, nws yog cov muaj zog acid ntawm saturated aliphatic monocarboxylic acids (pKa 3.75). Muaj ob qho tib si carboxyl thiab aldehyde functionalities, nws undergoes esterification, amidation, silver-daim iav, thiab txo cov tshuaj tiv thaiv. Nrog kwv yees li 45% ntawm kev siv tshuaj (analgin, aminopyrine, theophylline intermediates), 30% hauv tshuaj synthesis (formates, DMF, formamide), thiab 25% hauv tawv tanning, textile dyeing, roj hmab coagulation, thiab tsiaj pub additives (silage preservation), formic acid yog ntau yam tshuaj lom neeg. Muab faib ua cov khoom corrosive thiab flammable (UN 1779, Class 8+3); khaws cia rau hauv qhov chaw txias, qhov cua kom nruj nruj ntawm cov oxidizers, cov hauv paus muaj zog, thiab cov hlau ua haujlwm.
