Iyini i-Oxalic acid?

I-Oxalic acid iyinto ephilayo enefomula yamakhemikhali i-H₂C₂O₄.Kuyi-metabolite yezinto eziphilayo.Kuyi-dibasic weak acid.Isatshalaliswa kakhulu ezitshalweni, ezilwaneni nasezikhunjini, futhi idlala imisebenzi ehlukene ezintweni eziphilayo ezihlukene.I-anhydride yayo ene-asidi yi-carbon trioxide.Ukubonakala kwe-oxalic acid i-monoclinic flake engenambala noma ikristalu eyiprismatic noma impushana emhlophe, ayinaphunga, ukunambitheka okumuncu, kuncibilika kalula emanzini kodwa akuncibiliki ezincibilikisini eziphilayo njenge-ether.Isisindo samangqamuzana e-oxalic acid singama-90.0349.

Ukusetshenziswa kwe-oxalic acid: i-ejenti eyinkimbinkimbi, i-masking agent, i-precipitating agent, i-ejenti yokunciphisa.

1, njenge-ejenti yokuhlanza

I-Oxalic acid isetshenziswa kakhulu njenge-ejenti yokunciphisa kanye ne-blekning, esetshenziselwa ukukhiqizwa kwezidakamizwa ezinjengama-antibiotics kanye ne-borneol, njenge-solvent yokukhipha izinsimbi ezingavamile, njenge-ejenti yokunciphisa udayi, nanjenge-ejenti yokushuka.

I-Oxalic acid iphinde isetshenziswe ekukhiqizeni ama-cobalt-molybdenum-aluminium catalysts, ukuhlanzwa kwezinsimbi nemabula, kanye nokukhishwa kwezindwangu.

2. Njenge-ejenti yokunciphisa

Embonini ye-organic synthesis, isetshenziswa kakhulu ukukhiqiza imikhiqizo yamakhemikhali efana ne-hydroquinone, i-pentaerythritol, i-cobalt oxalate, i-nickel oxalate, ne-gallic acid.

Imboni yepulasitiki isetshenziselwa ukukhiqizwa kwe-polyvinyl chloride, aminoplastics, urea-formaldehyde plastics, lacquer sheets, njll.

Imboni kadayi isetshenziswa ekwenzeni i-magenta eluhlaza esekelwe kusawoti, njll.

Embonini yokunyathelisa nokudaya, ingangena esikhundleni se-acetic acid futhi isetshenziswe njengethuluzi lokuthuthukisa umbala kanye ne-bleaching ejenti yodayi be-pigment.

Imboni yezemithi isetshenziswa ekwenzeni i-chlortetracycline, i-oxytetracycline, i-tetracycline, i-streptomycin, ne-ephedrine.

Ngaphezu kwalokho, i-oxalic acid ingasetshenziswa futhi ekuhlanganiseni imikhiqizo ehlukahlukene efana ne-oxalate, i-oxalate ne-oxalamide, phakathi kwayo i-diethyl oxalate, i-sodium oxalate ne-calcium oxalate ikhiqiza kakhulu.

3. Njengomuthi

I-Antimony oxalate ingasetshenziswa njenge-mordant, futhi i-ferric ammonium oxalate iyi-ejenti yokuphrinta amapulani.

4 Umsebenzi wokukhipha ukugqwala

I-Oxalic acid ingasetshenziswa ukususa ukugqwala: thenga ibhodlela le-oxalic acid esitolo esithengisa ama-reagents amakhemikhali, thatha, wenze isisombululo ngamanzi afudumele, ulisebenzise ku-rust stain bese usula.(Qaphela: Qaphela uma usebenzisa, i-oxalic acid igqwala kakhulu kunsimbi engagqwali. I-Oxalic acid ene-high concentration ibuye ibe lula ukugqwala izandla. Futhi i-acid oxalate ekhiqizwayo iyancibilika kakhulu, kodwa inezinga elithile lobuthi. Ungayidli. uma usebenzisa . Ngemva kokuba isikhumba sihlangane ne-oxalic acid, kufanele sigezwe ngamanzi kusenesikhathi.)

Ukugcinwa kwe-Oxalic acid

1. Gcina endaweni eyomile nepholile.Ivikela ngokuqinile umswakama, ingangeni manzi, ivikela ilanga.Izinga lokushisa lesitoreji akufanele lidlule ku-40 ℃.

2. Zigcine kude nama-oxide nezinto ezine-alkaline.Ipakishwe esikhwameni esilukiwe se-polypropylene esifakwe isikhwama sepulasitiki.
