6. Indasitiri yehuku:Silage, nezvimwewo.

7. Vamwe: Inogonawo kugadzira kudhinda uye dhayi mordant.Coloring

uye kupedzisa mumiriri weFiber nebepa, Plasticizer,Kuchengeta Kudya patsva, Feed additive, etc.

8. Kugadzira cO:Chemical reaction: HCOOH=(dense H, So4catalyze)heat=CO+H，O

9.Deoxidizer: Test As, Bi, Al, Cu, Au, Im,Fe,Pb, Mn, Hg, Mo, Ag,Zn, etc.Test Ce, Re, Wo.Test amine primary amine, secondary amine.dis- solvant yekuedza molecular WT uye crystallization.Test methoxyl.

10.Fix-er for microscopic analysis.Kugadzira formate.chemical cleaningagent, Formic acid haina CL, inogona kushandiswa kuchenesa midziyo yesimbi isina tsvina.

Inopisa moto.Inogona kusanganiswa nemvura, ethanol, ether uye glycerol, uye yakawanda polar organic solvents, uye zvakare ine kumwe kunyungudika mumahydrocarbon.

Hukama density (d204) ndeye 1.220.Refractive index

1.3714.Iko kupisa kwemoto ndeye 254.4 kJ / mol, iyo yakakosha tembiricha i306.8 ℃, uye yakanyanya kumanikidza ndeye 8.63 MPa.Flash point 68.9 ℃ (kapu yakashama).Density 1.22, hama mhute density 1.59 (mhepo =1), saturated mhute pressure (24℃) 5.33kPa.

Kuwanda kwefomic acid kunowanzoita chando munguva yechando.

Mishonga inorambidzwa: yakasimba oxidant, alkali yakasimba, inoshanda simbi poda.

Zvimiro zvine ngozi: mhute nemhepo zvinoumba musanganiswa unoputika, unokonzera kupisa uye kuputika kana moto wakazaruka uye simba rinopisa.Inopindirana nemaoxidants akasimba.

Solubility: kusanganiswa nemvura, kusanyungudika mumahydrocarbon, kusanganiswa mudoro.

Mumahydrocarbon uye gaseous states, formic acid inoitika semadimers akasungwa nehydrogen bond.Munzvimbo ine gasi, hydrogen bonding inoguma nekutsauka kukuru pakati pefomic acid gasi uye yakanaka gasi equation yenyika.Liquid uye yakasimba formic acid ine inoenderera formic acid mamorekuru akasungwa nehydrogen bond.

Formic acid yakaora kuita CO uye H2O pasi pecatalysis ye concentrated sulfuric acid:

Nekuda kwechimiro chakakosha chefomic acid, imwe yemaatomu ayo ehydrogen yakabatana zvakananga neboka recarboxyl.Kana kuti unogona kuiona sehydroxyformaldehyde.Saka formic acid ine zvese asidhi uye aldehyde zvivakwa.

Formic acid ine zvinhu zvakafanana nemamwe akawanda carboxylic acids, kunyange mumamiriro ezvinhu akajairika formic acid haigadziri acyl chloride kana anhydride.Kupera kwemvura kunoodza formic acid kuita kabhoni monoxide nemvura.Formic acid ine zvakafanana kuderedza zvivakwa kune aldehydes.Inogona kutanga kuita girazi resirivheri kuita, kudzikisa maion esirivheri mune sirivheri ammonia yakaoma ion kuita sirivheri simbi, uye pachayo inoiswa oxidized mucarbon dioxide nemvura:

Formic acid ndiyo yega carboxylic acid inogona kuwedzerwa kune olefins.Formic acid mukuita kweasidhi (senge sulfuric acid, hydrofluoric acid), uye olefins inokurumidza kuita kuti iite mafomati.Nekudaro, kuita kwepadivi kwakafanana nekuita kweKoch kunogonawo kuitika, nechigadzirwa chiri chepamusoro carboxylic acid.

Pair value ye octanol/water partition coefficient: -0.54, yekumusoro kuputika muganho % (V/V) : 57.0, yakaderera kuputika muganhu % (V/V) : 18.0.

Formic acid ndeye yakasimba yekudzikisa mumiriri uye sirivheri girazi reaction inogona kuitika.Ndiyo yakanyanya acidic mu saturated fatty acids, uye iyo dissociation yenguva dzose ndeye 2.1 × 10-4.Inoputsika zvishoma nezvishoma kuita kabhoni monoxide uye mvura pane tembiricha yekamuri.Iyo inopisa kusvika ku60 ~ 80 ℃ ine concentrated sulfuric acid kuti iparadze uye ibudise kabhoni monoxide.Kana formic acid yadziyirwa pamusoro pe160 ° C, inoora kuburitsa kabhoni dhaidhisiki nehydrogen.Iyo alkali simbi munyu yefomic acid inodziya kusvika 400 ° C kuita oxalates.
