Njirimara physicochemical:
1.White ntụ ntụ: mmịpụta mmiri, obere isi nke formic acid.
2. Ebe mgbaze: 253 ℃
3. Njupụta nke ikwu: 1.191g / cm3
4.Solubility: Soluble na glycerin, ntakịrị mmanya na-aba n'anya, mmanya na-aba n'anya, na-adịghị edozi na ether.

Nchekwa
1.Chekwaa n'ebe dị jụụ, kpọrọ nkụ, nke ọma, zere ìhè anyanwụ kpọmkwem, pụọ na okpomọkụ, acid, mmiri na ikuku iru mmiri.
2.Sealing akọrọ preservation.Lined na plastic Ibé akwụkwọ dị, na uwe kpara akpa mbukota. Dị ka akọwapụtara na nchekwa kemịkalụ izugbe na njem njem.

Jiri
1.Jiri na akpụkpọ anụ ụlọ ọrụ, dị ka akpụkpọ anụ tanning, catalyzer, disifec-tor eji dị ka camouflage nnu na chrome tanning usoro.
2.Use na catalyst na stabilizer mejupụtara
3. Jiri na akwa akwa dị ka ihe na-ebelata.
4. Eji na akụrụngwa maka imepụta sodium hydrosul-phite, formic acid na oxalic acid
5. A na-eji ya dị ka ihe na-egbochi oyi na oyibo na kọmpụta
6. precipitate dị oké ọnụ ahịa ọla
7. Dị ka ihe nchekwa ihe, na-edozi uru nke PHin siri ike acid

Isi ihe eji eme ihe bụ ndị a: (1) A na-ejikarị emepụta formic acid, oxalic acid na mkpuchi ntụ ntụ, nke a na-ejikwa na mmepụta nke dimethylformamide, wdg. A na-ejikwa ya na nkà mmụta ọgwụ, mbipụta na ụlọ ọrụ dyeing. ; (2) reagents, disinfectants na mordant maka mkpebi nke phosphorus na arsenic;

(3) Eji mee ihe dị ka ihe nchekwa. Jiri anọ: maka mkpuchi resin alkyd, plasticizer, ike; (4) Ejiri ya dị ka ihe mgbawa, ihe na-eguzogide acid, mmanụ mmanụ ụgbọ elu, ihe mgbakwunye. Sodium formate n'ichepụta usoro (1) The mmeghachi omume nke carbon monoxide na sodium hydroxide ngwọta na 160 ~ 200 ℃ na 2MPa mgbali na-emepụta sodium formate, na mgbe ahụ site sulfuric acid hydrolysis, distillation nweta okokụre formic acid. Usoro mmeghachi omume bụ isi bụ: CO + NaOH → HCOONa2HCOONa + H2SO4 → 2HCOOH + Na2SO4 (2) iji mepụta ihe ndị sitere na neopentylene glycol, pentaerythritol na trimethylol propane. [Ụlọ ọrụ mmepụta ihe] formic acid, oxalic acid. [Ntụkọ aka àgwà index]
