Sodium Formate

Sodium formateihupfu huchena hunonyungudutsa kana kuti crystalline, ine hwema hushoma hwe formic acid. Inonyungudika mumvura neglycerin, inonyungudika zvishoma mu ethanol, hainyungudike mu ether. Ine chepfu. Inogona kushandiswa mukugadzira formic acid, oxalic acid, formamide uye insurance powder, industry yeganda, chrome tannery camouflage acid, inoshandiswa muma catalysts.

Zvivakwa:Sodium formate ihupfu hwema crystalline chena, hune hygroscopic zvishoma, hunonhuhwirira zvishoma formic acid, hunonyungudika mumvura, hunonyungudika zvishoma mu ethanol, haunyungudike mu ether, huremu hwakati wandei 1.919, poindi yekunyungudika 253℃, hunyoro mumhepo, kugadzikana kwemakemikari.

Mashandisirwo makuru:

Mashandisirwo makuru anoshandiswa muindasitiri yematehwe ndeaya anotevera:

(1) Inonyanya kushandiswa mukugadzira formic acid, oxalic acid uye insurance powder, asiwo inoshandiswa mukugadzira dimethylformamide, nezvimwewo. Inoshandiswawo mukurapa, kudhinda uye dhayi.

(2) ma reagents, mishonga yekuuraya utachiona uye mordant yekuona phosphorus ne arsenic;

(3) Inoshandiswa sechinochengetedza. che alkyd resin coating, plasticizer, yakasimba;

(4) Inoshandiswa sezvinhu zvinoputika, zvinhu zvisingapindi acid, mafuta ekuzora endege, uye zvinonamira.

Sodium formate uyeCaluminium formate:

Sodium formate necalcium formate imunyu miviri yesimbi inowanikwa muformate. Sodium formate inozivikanwawo sesodium formate. Kune mhando mbiri dzemamorekuru emakemikari esodium formate muzvisikwa:

① Anhydrous sodium formate ihupfu hwemakristaro machena, hune chepfu shoma, hune chepfu. Huremu hwehuwandu i1.92(20℃) uye poindi yekunyunguduka i253℃. Inonyungudika mumvura, inonyungudika zvishoma muethanol, hainyungudike mu ether.

② Sodium dihydrate haina ruvara rwekristaro. Inonhuwa zvishoma neformic acid, ine chepfu. Inonyungudika mumvura neglycerin, inonyungudika zvishoma muethanol. Pakupisa kwakanyanya, inopwanyika kuita hydrogen nesodium oxalate, uye pakupedzisira kuita sodium carbonate. Inogadzirwa nekubatana kweformic acid nesodium hydroxide.

Mashandisirwo makuru e sodium formate ndeaya anotevera:

Sodium formate inogona kushandiswa se reagent yekuongorora makemikari, inoshandiswa pakuona huwandu hwearsenic nephosphorus, asiwo inoshandiswa semushonga wekuuraya utachiona, mordant, nezvimwewo. Muindasitiri, sodium formate yeupfu inoshandiswa kutsiva formic acid kuvandudza mashandiro eFGD system ye limestone.

Nzira yekugadzirira sodium formate:Sodium bicarbonate inoshandiswa murabhoritari kuita zvinoenderana ne formic acid kuchengetedza mhinduro iri alkaline, kubvisa Fe3+, kusefa, kuisa formic acid mu filtrate, kuita kuti mhinduro ive ne acid shoma, kupwanyika uye kuita crystallize kuti pave ne crude sodium formate.

Calcium formate ihupfu huchena hunoyerera husina kuzara hune simba rekudzivirira kuumbwa, ngura uye mabhakitiriya. Inowedzera organic acid feed. Hunhu hwe99%, 69% formic acid, 31% calcium, mvura shoma. Chigadzirwa ichi chine poindi yekunyunguduka yakawanda uye hazvisi nyore kuparadzwa muzvinhu zvakapwanyika. Wedzera 0.9% ~ 1.5% muchikafu. Chigadzirwa ichi chinoparadzanisa formic acid mudumbu, chinoderedza pH yemudumbu, chinochengetedza acidity yemudumbu, uye chinodzivirira kukura kwebhakitiriya, nokudaro chichidzora nekudzivirira kuitika kwemanyoka ane chekuita nehutachiona hwebhakitiriya. Trace formic acid inogona kumutsa kushanda kwepepsinogen uye kuvandudza kunyudzwa kwezvinhu zvinoshanda muchikafu. Chelate nemaminerari muchikafu kukurudzira kugaya nekunyudzwa kwemaminerari; Inogona zvakare kushandiswa se calcium supplement. Inogona kudzivirira manyoka uye kuvandudza mwero wekurarama kwenguruve. Kukurudzira kushandurwa kwechikafu uye kuwedzera kuwedzera kwezuva nezuva.

Kurongedza, kuchengetera uye kutakurwa:Mapakeji akavharwa mumadhiramu esimbi akafukidzwa nepurasitiki, akachengetwa munzvimbo inotonhorera, yakaoma, ine mhepo yakanaka, kudzivirira zuva rakananga, kure nemhepo inopisa, acid, mvura, uye mhepo ine hunyoro.

Mukupedzisa, sodium formate chinhu chakakosha chinoita basa guru mumaindasitiri akasiyana-siyana. Chinoshandiswa mukugadzira makemikari akawanda anodiwa, anosanganisira formic acid, oxalic acid, formamide, uye dimethylformamide, uye chinoshandiswawo mumaindasitiri ematehwe. Kusasvibisa nharaunda, kugara kwenguva refu, uye kushandiswa kwakasiyana-siyana kunoita kuti ive sarudzo yakanaka mumashandisirwo akasiyana-siyana. Saka, chinhu chakakosha kuongororwa nemaindasitiri chinogona kubatsirwa zvakanyanya nehunyanzvi hwacho.
