Inqubo

SiyakhiqizaI-Formic Acidnge-Methyl Formate ethuthuke kakhulu

ubuchwepheshe. Okokuqala, i-Methyl Formate ikhiqizwa yi-CO ne-Methanolwith isenzo se-catalyst. Ngaphansi kwezinga lokushisa elithile nokucindezela, i-Methyl Formate igaywa nge-hydrolyzed ibe yi-Formic Acid. Ukuhlanzeka okuphansi kwe-Formic Acidsolution kuzogxilwa kweziphakeme ukuze kuhlangatshezwane nezidingo ezahlukene-

amakhasimende.

Isilinganiso sokusabela:HCOOCH3+H2O HCOOH+CH3OH Ukukhiqiza

7. Abanye: Ingakwazi futhi ukukhiqiza ukuphrinta nokudaya i-mordant.Coloring

kanye ne-ejenti yokuqedela ye-Fiber nephepha, i-Plasticizer, ukugcinwa okusha kokudla, isithasiselo sokuphakelayo, njll.

8. Ukukhiqiza i-cO:Ukusabela kweChemical: HCOOH=(minyene H, So4catalyze)heat=CO+H，O

9.Deoxidizer: Test As,Bi,Al,Cu,Au,Im,Fe,Pb,Mn,Hg,Mo,Ag,Zn, njll.Test Ce, Re, Wo.Test amine primary enuka kamnandi,i-amine yesibili.dis- i-solvant yokuhlola i-molecular WT kanye ne-crystallization.Test methoxyl.

10.Fix-er for microscopic analysis.Ukukhiqiza i-formate.chemical cleaningagent, Formic acid ayinayo i-CL, ingasetshenziselwa ukuhlanza impahla yensimbi engagqwali.

Ukusetshenziswa okuyinhloko kungokulandelayo: (1) Ikakhulukazi esetshenziswa ekukhiqizeni i-formic acid, i-oxalic acid kanye nempushana yomshwalense, iphinde isetshenziswe ekukhiqizeni i-dimethylformamide, njll. Ibuye isetshenziswe embonini yezokwelapha, yokunyathelisa nokudaya. ; (2) ama-reagents, ama-disinfectants kanye ne-mordant yokunquma i-phosphorus ne-arsenic;

(3) Isetshenziswa njengesivikelo. Sebenzisa ezine: for alkyd resin enamathela, plasticizer, eqinile; (4) Isetshenziswa njengeziqhumane, izinto ezimelana ne-asidi, uwoyela wokuthambisa wendiza, izithasiselo ezinamathelayo. Indlela yokukhiqiza ye-sodium formate (1) Ukusabela kwekhabhoni monoxide nesisombululo se-sodium hydroxide ku-160 ~ 200 ℃ kanye nokucindezela kwe-2MPa ukukhiqiza i-sodium formate, bese kuthi nge-sulfuric acid hydrolysis, i-distillation ukuze uthole i-formic acid eqediwe. I-equation yokusabela eyinhloko ithi: CO+NaOH→HCOONA2HCOONA + H2SO4→ 2HCOOH + Na2SO4 (2) ukukhiqiza imikhiqizo ephumayo ye-neopentylene glycol, pentaerythritol ne-trimethylol propane. [Uchungechunge lwemboni] i-formic acid, i-oxalic acid. [Inkomba yekhwalithi yesithenjwa]
