Yintoni i-Oxalic acid?

Iasidi ye-Oxalic yinto ephilayo enefomula yeekhemikhali i-H₂C₂O₄.Yimetabolite yezinto eziphilayo.Yi-asidi ebuthathaka ye-dibasic.Isasazwa ngokubanzi kwizityalo, izilwanyana kunye nokungunda, kwaye idlala imisebenzi eyahlukeneyo kwizinto eziphilayo ezahlukeneyo.I-asidi yayo ye-anhydride yi-carbon trioxide.Inkangeleko ye-oxalic acid yiflake ye-monoclinic engenambala okanye iprismatic crystal okanye umgubo omhlophe, ongenavumba, incasa emuncu, inyibilika ngokulula emanzini kodwa ayinyibiliki kwizinyibilikisi ze-organic ezifana ne-ether.Ubunzima bemolekyuli ye-oxalic acid yi-90.0349.

Ukusetyenziswa kwe-asidi ye-oxalic: i-agent edibeneyo, i-agent agent, i-agent ye-precipitating, i-agent yokunciphisa.

1, njenge-ejenti yokuthambisa

I-asidi ye-oxalic isetyenziswa kakhulu njenge-arhente yokunciphisa kunye ne-agent e-bleaching, isetyenziselwa ukuveliswa kwamachiza afana ne-antibiotics kunye ne-borneol, njenge-solvent yokutsalwa kweentsimbi ezinqabileyo, njenge-arhente yokunciphisa idayi, kunye ne-arhente yokutshisa.

I-asidi ye-Oxalic ikwasetyenziselwa ukuveliswa kwe-cobalt-molybdenum-aluminium catalysts, ukucocwa kwesinyithi kunye ne-marble, kunye ne-bleaching of textiles.

2. Njenge-arhente yokunciphisa

Kwishishini le-organic synthesis, lisetyenziswa ikakhulu ukuvelisa iimveliso zeekhemikhali ezifana ne-hydroquinone, i-pentaerythritol, i-cobalt oxalate, i-nickel oxalate, kunye ne-gallic acid.

Imboni yeplastiki isetyenziselwa ukuveliswa kwe-polyvinyl chloride, i-aminoplastics, iiplastiki ze-urea-formaldehyde, ii-lacquer sheets, njl.

Ishishini ledayi lisetyenziswa ekwenzeni ityuwa-esekelwe kwi-magenta eluhlaza, njl.

Kumashishini oshicilelo kunye nokudaya, inokuthi ithathe indawo yeacetic acid kwaye isetyenziswe njengoncedo lokuphuhlisa umbala kunye ne-ejenti yokujikijelwa kwedayi yebala.

Ishishini lamachiza lisetyenziswa ekwenzeni i-chlortetracycline, i-oxytetracycline, i-tetracycline, i-streptomycin, kunye ne-ephedrine.

Ukongeza, i-oxalic acid ingasetyenziselwa ukwenza iimveliso ezahlukeneyo ezifana ne-oxalate, i-oxalate kunye ne-oxalamide, phakathi kwayo i-diethyl oxalate, i-sodium oxalate kunye ne-calcium oxalate zezona zivelisa kakhulu.

3. Njenge-mordant

I-Antimony oxalate ingasetyenziswa njenge-mordant, kwaye i-ferric ammonium oxalate yi-arhente yokuprinta iiplani.

4 Umsebenzi wokususa umhlwa

I-asidi ye-oxalic ingasetyenziselwa ukususa i-rust: thenga ibhotile ye-oxalic acid kwivenkile ethengisa ii-reagents zamachiza, thatha, wenze isisombululo ngamanzi afudumeleyo, uyisebenzise kwi-rust stain kwaye uyisule.(Qaphela: Lumka xa usebenzisa, i-asidi ye-oxalic igqwesa kakhulu kwintsimbi engatyiwayo. I-asidi ye-oxalic ene-concentration ephezulu ilula ukuyidla ngezandla. Kwaye i-acid oxalate eveliswayo iyanyibilika kakhulu, kodwa inomlinganiselo othile wetyhefu. Musa ukuyitya. Xa ulusu ludibana ne-oxalic acid, kufuneka luhlanjwe ngamanzi kwangethuba.)

Ukugcinwa kweasidi ye-oxalic

1. Gcina kwindawo eyomileyo nepholileyo.Ubungqina obuqinileyo bokufuma, ukungangeni kwamanzi, i-sunscreen.Ubushushu bokugcina akufunekanga budlule kwi-40 ℃.

2. Gcina kude kwii-oxides kunye nezinto zealkaline.Ipakishwe kwi-polypropylene ephothiweyo kwingxowa eyenziwe ngeplastiki.
