Ntchito yayikulu ya sodium formate

Zomwe zimagwiritsidwa ntchito kwambiri ndi sodium formate,
China Chemical opanga, Opanga achi China, opanga mankhwala apanyumba, opanga zapakhomo, opanga sodium formate m'nyumba, Sodium Formate, Opanga sodium formate, zitsanzo za sodium formate, ntchito ya sodium formate,
Physicochemical katundu:
1.White ufa: Kuthira madzi, kununkhira pang'ono kwa formic acid.
2. Malo osungunuka: 253 ℃
3.Kuchulukana kwachibale: 1.191g/cm3
4.Kusungunuka: Kusungunuka mu glycerin, kusungunuka pang'ono mu mowa, mowa, kusungunuka mu ether.

Storge
1.Sungani pamalo ozizira, owuma, opanda mpweya wabwino, pewani kuwala kwa dzuwa, kutali ndi kutentha, asidi, madzi, ndi mpweya wonyowa.
2.Kusindikiza dry preservation.Kumangirira ndi mapepala apulasitiki zilipo, ndi malaya woven thumba kulongedza. Monga mmene ambiri mankhwala kusungirako ndi mayendedwe.

Kufotokozera za khalidwe

Gwiritsani ntchito
1.Imagwiritsidwa ntchito m'makampani achikopa, monga kufufuta zikopa, chothandizira, chothandizira kutikita minofu chomwe chimagwiritsidwa ntchito ngati mchere wobisala munjira yowotchera chrome.
2.Gwiritsani ntchito muzothandizira ndi zokhazikika
3. Gwiritsani ntchito utoto wa nsalu ngati chochepetsera.
4. Ntchito mu zopangira kupanga sodium hydrosul-phite, formic acid ndi asidi oxalic
5. Amagwiritsidwa ntchito ngati anti-frosting wothandizira mu konkire
6. mpweya wamtengo wapatali
7. Monga buffer action , kusintha mtengo wa PHin amphamvu asidi

Ntchito zazikuluzikulu ndi izi: (1) Zomwe zimagwiritsidwa ntchito makamaka popanga formic acid, oxalic acid ndi ufa wa inshuwalansi, womwe umagwiritsidwanso ntchito popanga dimethylformamide, ndi zina zotero. ; (2) reagents, mankhwala ophera tizilombo ndi mordant kudziwa phosphorous ndi arsenic;

(3) Amagwiritsidwa ntchito ngati chosungira. Gwiritsani ntchito zinayi: zokutira alkyd utomoni, plasticizer, wamphamvu; (4) Amagwiritsidwa ntchito ngati zophulika, zinthu zosagwira asidi, mafuta opaka ndege, zomatira. Sodium formate kupanga njira (1) Mmene mpweya monoxide ndi sodium hydroxide njira pa 160 ~ 200 ℃ ndi 2MPa kuthamanga kubala sodium formate, ndiyeno mwa sulfuric asidi hydrolysis, distillation kupeza yomalizidwa formic acid. Equation yayikulu ndi: CO+NaOH→HCOONA2HCOONa + H2SO4→ 2HCOOH + Na2SO4 (2) kupanga zopangira za neopentylene glycol, pentaerythritol ndi trimethylol propane. [Industry chain] formic acid, oxalic acid. [Chilolezo chamtundu wamawu]
