Sodium Formate

Sodium formateyog dawb absorbent hmoov los yog crystalline, nrog me ntsis formic acid tsw.Soluble hauv dej thiab glycerin, me ntsis soluble hauv ethanol, insoluble hauv ether.Tshuaj lom.Yuav siv tau nyob rau hauv zus tau tej cov formic acid, oxalic acid, formamide thiab pov hwm hmoov, tawv kev lag luam, chrome tannery camouflage acid, siv nyob rau hauv catalysts.

Khoom:Sodium formate yog dawb crystalline hmoov, me ntsis hygroscopic, me ntsis formic acid tsw, soluble nyob rau hauv dej, me ntsis soluble nyob rau hauv ethanol, insoluble nyob rau hauv ether, tshwj xeeb gravity 1.919, melting point 253 ℃, delix nyob rau hauv huab cua, tshuaj stability.

Cov ntawv thov tseem ceeb:

Siv hauv kev lag luam tawv, kev siv tseem ceeb yog raws li hauv qab no:

(1) Feem ntau yog siv rau hauv kev tsim cov formic acid, oxalic acid thiab kev tuav pov hwm hmoov, tab sis kuj siv rau hauv kev tsim cov dimethylformamide, thiab lwm yam. Kuj tseem siv rau hauv kev lag luam tshuaj, luam ntawv thiab dyeing.;

(2) reagents, tshuaj tua kab mob thiab mordant rau kev txiav txim siab ntawm phosphorus thiab arsenic;

(3) Siv los ua preservative.for alkyd resin txheej, plasticizer, muaj zog;

(4) Siv los ua cov khoom tawg, cov ntaub ntawv acid-resistant, aviation lubricating roj, nplaum additives.

Sodium formate thiabCAlcium formate:

Sodium formate thiab calcium formate yog ob hom hlau ntsev ntawm formate.Sodium formate tseem hu ua sodium formate.Muaj ob hom molecular ntawm sodium formate compounds nyob rau hauv qhov:

① Anhydrous sodium formate yog dawb crystalline hmoov, me ntsis hygroscopic, tshuaj lom.Cov txheeb ze ntom ntom yog 1.92 (20 ℃) ​​thiab cov ntsiab lus melting yog 253 ℃.Soluble nyob rau hauv dej, me ntsis soluble nyob rau hauv ethanol, insoluble nyob rau hauv ether.

② Sodium dihydrate yog siv lead ua tsis muaj xim.Me ntsis formic acid tsw, lom.Soluble hauv dej thiab glycerin, me ntsis soluble hauv ethanol.Thaum tshav kub kub, nws tawg mus rau hauv hydrogen thiab sodium oxalate, thiab thaum kawg mus rau sodium carbonate.Nws yog tsim los ntawm kev sib cuam tshuam ntawm formic acid nrog sodium hydroxide.

Kev siv tseem ceeb ntawm sodium formate yog raws li hauv qab no:

Sodium formate tuaj yeem siv los ua cov tshuaj ntsuam xyuas reagent, siv rau kev txiav txim siab ntawm cov ntsiab lus arsenic thiab phosphorus, tab sis kuj siv los ua tshuaj tua kab mob, mordant, thiab lwm yam. Hauv kev lag luam, hmoov sodium formate yog siv los hloov cov formic acid los txhim kho kev ua haujlwm ntawm limestone. FGD qhov system.

Txoj kev npaj ntawm sodium formate:Sodium bicarbonate yog siv nyob rau hauv lub chaw soj nstuam rau react nrog formic acid kom cov tshuaj alkaline, tshem tawm Fe3+, lim, ntxiv formic acid rau hauv lub filtrate, ua kom cov tshuaj weakly acidic, evaporate thiab crystallize kom tau crude sodium formate.

Calcium formate yog cov dawb ntws dawb crystalline hmoov nrog los tiv thaiv pwm, tiv thaiv corrosion thiab tshuaj tua kab mob.Nws yog ib qho organic acid pub additive.Cov ntsiab lus ntawm 99%, 69% formic acid, 31% calcium, dej cov ntsiab lus tsawg.Cov khoom no muaj cov ntsiab lus melting siab thiab tsis yooj yim rau kev puas tsuaj hauv cov khoom siv granular.Ntxiv 0.9% ~ 1.5% hauv kev pub.Cov khoom no cais cov formic acid nyob rau hauv lub plab, txo cov pH ntawm lub plab, tswj cov acidity ntawm lub plab zom mov, thiab tiv thaiv kev loj hlob ntawm cov kab mob pathogenic, yog li tswj thiab tiv thaiv qhov tshwm sim ntawm raws plab txuam nrog cov kab mob.Trace formic acid tuaj yeem qhib qhov kev txiav txim ntawm pepsinogen thiab txhim kho kev nqus ntawm cov khoom xyaw nquag hauv pub.Chelate nrog cov zaub mov hauv pub los txhawb kev zom zaub mov thiab nqus cov zaub mov;Nws kuj tseem siv tau los ua calcium ntxiv.Nws tuaj yeem tiv thaiv raws plab thiab txhim kho kev ciaj sia ntawm piglets.Txhawb kev hloov pauv pub noj thiab nce kev nce txhua hnub.

Ntim, cia thiab thauj:Muab ntim ntim rau hauv cov nruas hlau uas muaj cov zaj duab xis yas, khaws cia rau hauv qhov chaw txias, qhuav, zoo-ventilated qhov chaw, tsis txhob raug tshav ntuj ncaj qha, deb ntawm tshav kub, kua qaub, dej, huab cua.

Hauv kev xaus, sodium formate yog ib qho tseem ceeb compound uas ua lub luag haujlwm tseem ceeb hauv ntau yam kev lag luam.Nws yog siv los tsim ntau yam tshuaj tsim nyog, suav nrog formic acid, oxalic acid, formamide, thiab dimethylformamide, thiab tseem siv hauv kev lag luam tawv.Nws eco-friendliness, durability, thiab versatility ua rau nws ib tug zoo tagnrho xaiv nyob rau hauv ntau daim ntawv thov.Yog li ntawd, nws yog ib qho tsim nyog tshawb nrhiav los ntawm kev lag luam uas tuaj yeem tau txais txiaj ntsig zoo tshaj plaws los ntawm nws cov khoom.
