Kev siv tseem ceeb ntawm sodium formate

Kev siv tseem ceeb ntawm sodium formate,
Tuam Tshoj Chemical manufacturers, Suav manufacturers, domestic chemical manufacturers, domestic manufacturers, domestic sodium formate manufacturers, Sodium Formate, Sodium formate manufacturers, sodium formate qauv, sodium formate lub luag haujlwm,
Physicochemical zog:
1.White hmoov: dej nqus, me ntsis tsw ntawm formic acid.
2. Melting point: 253 ℃
3.Relative ntom: 1.191g/cm3
4.Solubility: Soluble hauv glycerin, me ntsis soluble hauv cawv, cawv, insoluble hauv ether.

Storge
1. Khaws rau hauv qhov chaw txias, qhuav, zoo-ventilated, tsis txhob tshav ntuj ncaj qha, kom deb ntawm tshav kub, kua qaub, dej, thiab huab cua ntub.
2.Sealing qhuav preservation.Lined nrog cov ntawv yas yog muaj, thiab lub tsho tiv no woven hnab ntim. Raws li tau teev tseg hauv kev khaws tshuaj thiab kev thauj mus los.

Khoom specification

Siv
1.Siv nyob rau hauv tawv kev lag luam, raws li tawv tanning, catalyzer, disifec-tor siv raws li camouflage ntsev nyob rau hauv chrome tanning txoj kev
2.Siv nyob rau hauv catalyst thiab stabilizer compositions
3. Siv nyob rau hauv textile dyeing raws li ib tug txo tus neeg sawv cev.
4. Siv rau hauv cov khoom siv raw rau kev tsim cov sodium hydrosul-phite, formic acid thiab oxalic acid
5. Siv los tiv thaiv frosting tus neeg sawv cev hauv pob zeb
6. precipitate precious hlau
7. Raws li tsis ua haujlwm, kho tus nqi ntawm PHin muaj zog acid

Cov 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, kuj siv nyob rau hauv zus tau tej cov dimethylformamide, thiab lwm yam. Kuj siv nyob rau hauv cov tshuaj, luam ntawv thiab dyeing kev lag luam. ; (2) reagents, tshuaj tua kab mob thiab mordant rau kev txiav txim siab ntawm phosphorus thiab arsenic;

(3) Siv raws li kev khaws cia. Siv plaub: rau 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 manufacturing method (1) Cov tshuaj tiv thaiv ntawm carbon monoxide thiab sodium hydroxide tov ntawm 160 ~ 200 ℃ thiab 2MPa siab los tsim sodium formate, thiab tom qab ntawd los ntawm sulfuric acid hydrolysis, distillation kom tau cov formic acid tiav. Lub ntsiab lus sib npaug yog: CO + NaOH → HCOONa 2HCOONa + H2SO4 → 2HCOOH + Na2SO4 (2) los tsim cov khoom ntawm neopentylene glycol, pentaerythritol thiab trimethylol propane. [Industry saw] formic acid, oxalic acid. [Reference quality index]
