Isticmaalka ugu muhiimsan ee qaabka sodium,
Warshadaha Kiimikada ee Shiinaha, Warshadaha Shiinaha, soosaarayaasha kiimikada gudaha, warshadeeyayaasha gudaha, warshadeeyayaasha qaabka soodhiyamka gudaha, Sodium Formate, Soosaarayaasha qaabdhismeedka sodium, moodooyinka qaabka sodium, doorka qaabka sodium,
Astaamaha physicochemical:
1.Budada cad: nuugista biyaha, ur yar oo ah formic acid.
2.Dhibka dhalaalka: 253℃
3.Cafnaanta qaraabada: 1.191g/cm3
4.Solubility: Ku milma glycerin, wax yar oo khamriga ah, khamriga, aan la karinin ether.

Kaydka
1. Ku kaydi meel qabow, qalalan, oo hawo fiican leh, ka fogow iftiinka qorraxda tooska ah, ka fog kulaylka, aashitada, biyaha, iyo hawada qoyan.
2.Xabaynta ilaalinta qalalan.Waxaa lagu dahaadhay bac balaastiig ah,iyo bacaha dharka togan. Sida ku qeexan kaydinta kiimikada guud iyo gaadiidka.

Tilmaamaha tayada

Isticmaal
1. Isticmaala warshadaha maqaarka, sida harag maqaar ah, katalyzer, disifec-tor loo isticmaalo sida milix camouflage ee habka madaw ee chrome
2.Isticmaal halabuurka kicinta iyo xasilinta
3. U adeegso dheehaynta dunta sida wakiilka yaraynta.
4. Loo isticmaalo alaabta ceeriin ee soo saarista sodium hydrosul-phite, formic acid iyo oxalic acid
5. Loo isticmaalo sidii wakiilka barafowga ee shubka
6. soo dedejiya birta qaaliga ah
7. Sida fal-dejinta, hagaajinta qiimaha PHin aashitada xoogga leh

Isticmaalka ugu muhiimsan waa sida soo socota: (1) Inta badan waxaa loo isticmaalaa soo saarista formic acid, oxalic acid iyo budada caymiska, oo sidoo kale loo isticmaalo soo saarista dimethylformamide, iwm. Sidoo kale loo isticmaalo daawada, daabacaadda iyo warshadaha rinjiyeynta. ; (2) reagents, jeermis dileyaal iyo mordant si loo go'aamiyo fosfooraska iyo arsenic;

(3) Waxa loo istcimaalaa sidii wax lagu ilaaliyo. Isticmaal afar: daaha alkyd resin, balaastik, xoog leh; (4) Loo isticmaalo sida walxaha qarxa, walxaha aashitada u adkaysta, saliidda duulista, waxyaabaha lagu daro. Habka wax soo saarka Sodium formate (1) falcelinta of carbon monoxide iyo sodium hydroxide xal at 160 ~ 200 ℃ iyo 2MPa cadaadis si loo soo saaro formate sodium, ka dibna iyada oo loo marayo sulfuric acid hydrolysis, distillation si aad u hesho formic acid dhammayn. Isla'egta falcelinta ugu weyni waa: CO+NaOH→HCOONa2HCOONa + H2SO4→ 2HCOOH + Na2SO4 (2) si loo soo saaro wax soo saarka neopentylene glycol, pentaerythritol iyo trimethylol propane. [Silsiladda warshadaha] formic acid, oxalic acid. [Tusmada tayada tixraaca]
