Formic Acid85

Ua yeeb yaj duab acid

Formic acid yog lub pob tshab flasless fluming nrog cov kua txob khaus. Nws yog cov kua qaub muaj zog. Nws tuaj yeem yaj nrog cov dej nyob hauv txhua qhov kev faib ua feem thiab tsim ib qho kev sib xyaw siab dua li qhov npau taws ntawm ob qho tib si. Ob leeg sawv daws soluble nrog ntau cov kuab tshuaj organic, tab sis insoluble hauv hydrocarbons. Combustible, thaum khaws cia ntev li 30 degree, formic acid yuav domompose maj mam thiab tso cov pa roj carbon monoxide. Nws cov vapor cov qauv tawg nrog huab cua, uas tuaj yeem ua rau cua thiab tawg thaum raug qhib hluav taws thiab kub. Nws tuaj yeem cuam tshuam nrog cov neeg sawv cev oxidising oxidising. Muaj zog corrosiveness. Corrodes Aluminium, Nrum Hlau, Hlau, qee qhov plastics, roj hmab thiab xim.

Formic acid yog cov acid tsis muaj zog acid (tsis muaj zog electrolyte) uas muaj acidic li qub ntawm 1.8 {{5} {{7} {7}}). HCOOH ⇌ HCOO {{{{{8} h +=3}}} and bicarbonates (eg, sodium bicarbonate) to formate and water, and it can also be displaced by metal monomers (eg, sodium, zinc, and magnesium) to produce hydrogen gas (to formate). Formic acid yog ib qho ntawm cov khoom siv tshuaj lom neeg organic, siv tshuaj tua kab, tawv, dyes, tshuaj thiab roj hmab kev lag luam thiab roj hmab. Formic acid tuaj yeem siv ncaj qha rau hauv cov ntaub ua kom zoo, tanning, textile dowing thiab ntsuab cov neeg saib xyuas hlau, roj hmab ntxiv. Nyob rau hauv cov synthic synthesis rau synthesis ntawm ntau cov acid acid esters, acridine dyes thiab formamide series ntawm cov tshuaj hauv tsev.
