Sodium Formate

Sodium formateichena inonwisa hupfu kana kuti crystalline, ine kakunhuwirira formic acid.Soluble mumvura uye glycerin, zvishoma soluble mu ethanol, isinganyunguriki mu ether.Toxic.Inogona kushandiswa mukugadzirwa kwefomic acid, oxalic acid, formamide uye inishuwarenzi hupfu, indasitiri yematehwe, chrome tannery camouflage acid, inoshandiswa mune zvinokonzeresa.

Properties:Sodium formate iwhite crystalline powder, zvishoma hygroscopic, zvishoma formic acid inonhuwa, inonyungudika mumvura, inonyungudika zvishoma mu ethanol, isinganyunguriki muether, chaiyo giravhiti 1.919, melting point 253 ℃, delix mumhepo, kugadzikana kwemakemikari.

Main applications:

Inoshandiswa muindasitiri yematehwe, iyo inonyanya kushandiswa ndeyekutevera:

(1) Inonyanya kushandiswa mukugadzirwa kwefomic acid, oxalic acid uye hupfu hweinishuwarenzi, asi inoshandiswawo mukugadzirwa kwedimethylformamide, nezvimwewo Inoshandiswawo mumishonga, kudhinda uye dhayi indasitiri.;

(2) reagents, disinfectants uye mordant yekugadzika kwephosphorus uye arsenic;

(3) Inoshandiswa sechinhu chinochengetedza.for alkyd resin coating, plasticizer, yakasimba;

(4) Inoshandiswa sezvinoputika, zvinodzivirira acid, mafuta ekuzora nendege, zvinonamira zvinowedzera.

Sodium formate uyeCalcium formate:

Sodium formate uye calcium formate ndiwo maviri akajairika simbi munyu wefomati.Sodium formate inozivikanwawo sesodium formate.Kune maviri ma molecular mafomu e sodium formate makomisheni mune zvakasikwa:

① Anhydrous sodium formate ichena crystalline poda, zvishoma hygroscopic, ine chepfu.Density yehukama ndeye 1.92 (20 ℃) ​​uye nzvimbo yekunyungudika i253 ℃.Soluble mumvura, zvishoma soluble mu ethanol, isinganyunguriki mu ether.

② Sodium dihydrate ikristaro isina ruvara.Zvishoma formic acid kunhuwa, chepfu.Soluble mumvura uye glycerin, zvishoma soluble mu ethanol.Pakupisa kukuru, inoputsika kuita hydrogen uye sodium oxalate, uye pakupedzisira mu sodium carbonate.Inogadzirwa nekubatana kwefomic acid ne sodium hydroxide.

Iko kushandiswa kukuru kwesodium formate ndeiyi inotevera:

Sodium formate inogona kushandiswa sekemikari yekuongorora reagent, inoshandiswa kugadzirisa arsenic uye phosphorus content, asi inoshandiswawo semishonga inouraya utachiona, mordant, nezvimwewo. Muindasitiri, powdered sodium formate inoshandiswa kutsiva formic acid kuvandudza kushanda kwemarara. FGD system.

Kugadzirira nzira ye sodium fomati:Sodium bicarbonate inoshandiswa murabhoritari kuita nefomic acid kuchengetedza mhinduro alkaline, bvisa Fe3+, sefa, wedzera formic acid mufiltrate, ita kuti mhinduro isaite acidic, kuputika uye crystallize kuti uwane crude sodium formate.

Calcium formate ndeye yakasununguka inoyerera chena crystalline poda ine anti-mold, anti-corrosion uye antibacterial mhedzisiro.Icho chinonzi organic acid feed additive.Zvinyorwa zve99%, 69% formic acid, 31% calcium, pasi pemvura.Ichi chigadzirwa chine yakakwira kunyungudika uye haisi nyore kuparadzwa mune granular zvinhu.Wedzera 0.9% ~ 1.5% mukudya.Ichi chigadzirwa chinoparadzanisa formic acid mudumbu, inoderedza pH yemudumbu, inochengetedza acidity yegumbo rekudya, uye inodzivirira kukura kwebhakitiriya yepathogenic, nokudaro kudzora nekudzivirira kuitika kwemanyoka ane chokuita nehutachiona hwehutachiona.Trace formic acid inogona kumisa chiito che pepsinogen uye kuvandudza kunyura kwezvinhu zvinoshanda mukudya.Chelate ine zvicherwa mukudya kusimudzira kugaya uye kutorwa kwemaminerari;Inogonawo kushandiswa se calcium supplement.Inogona kudzivirira manyoka uye kuvandudza mwero wekupona kwenguruve.Kurudzira kushandurwa kwechikafu uye kuwedzera kuwana zuva nezuva.

Kurongedza, kuchengetedza uye kutakura:Yakavharwa kurongedza mumadhiramu esimbi akaiswa firimu repurasitiki, akachengetwa munzvimbo inotonhorera, yakaoma, ine mhepo inofefetera, kudzivirira zuva rakananga, kure nekupisa, asidhi, mvura, mhepo inonyorova.

Mukupedzisa, sodium formate chinhu chakakosha chinoita basa rakakosha mumaindasitiri akasiyana.Inoshandiswa mukugadzirwa kwemakemikari akawanda anodiwa, anosanganisira formic acid, oxalic acid, formamide, uye dimethylformamide, uye inoshandiswawo muindasitiri yematehwe.Iyo eco-hushamwari, kusimba, uye kuita kwakasiyana-siyana kunoita kuti ive sarudzo yakanaka mune akati wandei maapplication.Saka nekudaro, iko komisheni inofanirwa kuongororwa nemaindasitiri ayo anogona kubatsira zvakanyanya kubva kune ayo zvinhu.
