Formic acid

piav qhia luv luv:

Cov kua dej tsis muaj xim nrog cov ntxhiab tsw.Formic acid yog ib qho tsis muaj zog electrolyte, yog ib qho ntawm cov organic chemical raw cov ntaub ntawv, dav siv nyob rau hauv tshuaj tua kab, tawv, dyes, tshuaj thiab roj hmab industries.Formic acid tuaj yeem siv ncaj qha rau hauv kev ua ntaub, tanning tawv, textile printing thiab dyeing thiab ntsuab pub cia, thiab tseem tuaj yeem siv los ua tus neeg sawv cev ntawm cov hlau, cov khoom siv roj hmab thiab cov khoom hnyav.

Formic acid yog tib cov kua qaub nyob rau hauv pawg carboxyl txuas nrog hydrogen atom, hydrogen atom repulsive electron quab yuam tsawg dua li cov hydrocarbon pawg, yog li ntawd cov carboxyl carbon atom electron ceev yog qis dua lwm cov carboxyl acids, thiab vim yog conjugation. cov nyhuv, cov carboxyl oxygen atom ntawm electron yog inclined rau carbon, yog li cov kua qaub muaj zog dua lwm cov carboxyl acids nyob rau hauv tib series.Formic acid nyob rau hauv aqueous tov yog ib tug yooj yim qaug zog acid, acidity coefficient (pKa) = 3.75 (ntawm 20 ℃), 1% formic acid tov pH nqi yog 2.2.

Kev siv tseem ceeb

Formic acid yog ib qho ntawm cov organic chemical raw cov ntaub ntawv, dav siv nyob rau hauv tshuaj tua kab, tawv, dyes, tshuaj thiab roj hmab industries.Formic acid tuaj yeem siv ncaj qha rau hauv kev ua ntaub, tanning tawv, textile printing thiab dyeing thiab ntsuab pub cia, thiab tseem tuaj yeem siv los ua tus neeg sawv cev ntawm cov hlau, cov khoom siv roj hmab thiab cov khoom hnyav.Nyob rau hauv cov organic synthesis, nws yog siv los ua ke ntau hom, acridine dyes thiab formamide series ntawm kev kho mob intermediates.Cov qeb tshwj xeeb yog raws li hauv qab no:

1. Pharmaceutical kev lag luam:

Nws tuaj yeem siv rau kev ua cov caffeine, aminopyrine, aminophylline, theobromine borneol, vitamin B1, metronidazole thiab mebendazole.

2. Kev lag luam tshuaj tua kab:

tuaj yeem siv rau hmoov xeb, triazolone, tricyclozole, triazole, triazolium, triazolium, polybulozole, tenobulozole, tshuaj tua kab, dicofol ua.

3. Kev lag luam tshuaj:

raw cov ntaub ntawv rau kev tsim ntau hom, formamide, pentaerythritol, neopentanediol, epoxy soybean roj, epoxy octyl soybean oleate, valeryl chloride, xim Remover thiab phenolic resin.

4. tawv kev lag luam:

siv los ua tawv tanning npaj, deashing agents thiab neutralizing agents.

5. Roj hmab kev lag luam:

rau kev ua cov roj hmab ntuj coagulants, roj hmab antioxidant manufacturing.

6. Laboratory ntau lawm CO. tshuaj tiv thaiv mis:

7. Cerium, rhenium thiab tungsten raug kuaj.Aromatic thawj amines, theem nrab amines thiab methoxy pawg tau kuaj.Cov txheeb ze molecular hnyav thiab crystalline solvent methoxyl pawg tau txiav txim.Siv ua fixative hauv microscopic tsom xam.

8. formic acid thiab nws cov kua aqueous tuaj yeem yaj ntau cov hlau, hlau oxides, hydroxides thiab ntsev, qhov tshwm sim formate tuaj yeem yaj hauv dej, yog li nws tuaj yeem siv los ua tshuaj ntxuav.Formic acid tsis muaj chloride ions thiab tuaj yeem siv los ntxuav cov khoom uas muaj cov khoom siv hlau stainless.

9. siv los npaj kua, papaya, jackfruit, qhob cij, cheese, cheese, qab zib thiab lwm yam edible tsw thiab whiskey, rum tsw.Qhov concentration hauv cov khoom noj qab zib kawg yog li 1 txog 18 mg / kg.

10. lwm tus: tuaj yeem tsim cov dyeing mordant, fiber ntau thiab daim ntawv dyeing tus neeg saib xyuas, tus neeg saib xyuas kev kho mob, plasticizer, kev txuag zaub mov, tsiaj pub additives thiab txo cov neeg ua haujlwm.
