I-Oxalic Acid

Iyini i-Oxalic Acid?

I-Oxalic acid, eyaziwa nangokuthi i-ethanedioic acid, iyikristale engenambala eqinile enefomula yamakhemikhali ethi C2H2O4. Ivela ngokwemvelo ezitshalweni ezihlukahlukene, kuhlanganise ne-rhubarb, isipinashi, nezinye izitshalo ezinamaqabunga. Ukwengeza, ingahlanganiswa ngezinqubo zamakhemikhali ezibandakanya i-nitric acid ne-sodium nitrate.

Izici ze-Oxalic Acid

Izakhiwo Zomzimba

I-Oxalic acid ikhombisa izinto ezibonakalayo ezithokozisayo. Icwebezela ngendlela yamakristalu angenaphunga, asobala ancibilika emanzini nasetshwaleni. Inhlanganisela inephuzu lokuncibilika cishe elingu-189 °C (372 °F) futhi ibilisa cishe ku-365 °C (689 °F). Inokunambitheka okune-asidi okuqinile futhi isabela kakhulu lapho ihlangana nezinye izinto.

Chemical Properties

Ngokwekhemikhali, i-oxalic acid iyisidi ephilayo eqinile ebhekana kalula nokusabela okufana ne-oxidation, ukunciphisa, kanye ne-esterification. Ihlangana nama-alkali akhe usawoti oncibilikayo obizwa ngokuthi ama-oxalate. Ngaphezu kwalokho, ingasebenza njenge-ejenti enciphisayo kokunye ukusabela, ibonise ukuguquguquka kwayo ezinqubweni ezihlukahlukene zamakhemikhali.

Ukusetshenziswa kwe-Oxalic Acid

I-Oxalic acid ithola ukusetshenziswa kuzo zombili izilungiselelo zezimboni nezasekhaya ngenxa yezakhiwo zayo ezihlukile. Ake sihlole okunye ukusetshenziswa kwayo okubalulekile:

Ukusetshenziswa Kwezimboni

1. Ukuhlanza Insimbi : I-Oxalic acid isebenza njengesihlanzi esisebenzayo sokugqwala namabala endaweni yensimbi. Isusa ukungcola ethusi, insimbi, nensimbi, iyenze ibe yingxenye ebalulekile ezinqubweni zokubuyisela insimbi.

   
   

2. I-Bleaching Agent : Ikhompiyutha isetshenziswa ezimbonini zokuxubha nokudaya ukususa umbala ezindwangu, ukhuni, nephepha. Isebenza njenge-ejenti enciphisayo, idiliza ama-chromophore anesibopho sombala.

   
   

Ukusetshenziswa Kwasekhaya

1. Umenzeli Wokuhlanza : I-Oxalic acid iyisithako esivamile emikhiqizweni ehlukahlukene yokuhlanza, ikakhulukazi ekususeni ukugqwala namabala aqinile amanzi. Ihlanza ngokuphumelelayo izitsha zasekhishini, amathayili, nempahla yokugezela.

   
   

2. Ukususwa kwe-Wood Stain : I-Oxalic acid ingasusa amabala abangelwa ukulimala kwamanzi noma idiphozi yensimbi ezindaweni zokhuni. Ivuselela ukubukeka kwefenisha futhi isuse amabala ngokuphumelelayo.

   
   

Imiphumela Yezempilo

Ubuthi

Nakuba i-oxalic acid inezicelo eziningi, kubalulekile ukuyiphatha ngokucophelela ngenxa yobuthi bayo. Ukungenisa noma ukuhogela i-oxalic acid eningi kakhulu kungaba yingozi empilweni yomuntu. Inhlanganisela ingase ibangele ukucasuka ohlelweni lokuphefumula, amehlo, nesikhumba. Ngaphezu kwalokho, kungaholela ekwakhekeni kwamakristalu e-calcium oxalate ezinso, okungase kubangele amatshe ezinso.

Izinyathelo Zokuphepha

Ukuqinisekisa ukuphathwa okuphephile kanye nokunciphisa izingozi zezempilo ezihlobene ne-oxalic acid, kubalulekile ukulandela izinyathelo zokuphepha ezifanele:

1. Igiya Lokuvikela : Uma usebenza nge-oxalic acid, gqoka izinto zokuzivikela ezifanele, okuhlanganisa amagilavu, izibuko zokuphepha, nejazi laselabhu, ukuvimbela ukuthintana okuqondile nesikhumba, amehlo, nezingubo.

   
   

2. Ukungenisa umoya : Qinisekisa ukungena komoya owanele endaweni yokusebenza ukuze unciphise ukuhogela komhwamuko we-oxalic acid. Uma usebenza endaweni evalekile, sebenzisa i-fume hood noma usebenze endaweni enomoya omuhle.

   
   

3. Isitoreji : Gcina i-oxalic acid esitsheni esivikelekile, esinelebula kude nezinto ezingahambelani. Yigcine lapho izingane nezilwane ezifuywayo zingakwazi ukufinyelela kuzo. Landela imithetho yendawo ukuze uthole izindlela ezifanele zokulondoloza nezindlela zokulahla.

   
   

4. I-Dilution : Uma usebenzisa izixazululo ze-oxalic acid, zihlambulule njalo ngokuvumelana neziqondiso ezinconyiwe. Gwema ukusebenzisa ukugxila okuphezulu ngaphandle kokuqeqeshwa okufanele noma ubuchwepheshe.

   
   

5. Usizo Lokuqala : Uma kwenzeka uthintana ngephutha noma udliwe, funa usizo lwezokwelapha ngokushesha. Hlanza izindawo ezithintekile ngamanzi amaningi futhi ukhiphe izingubo ezingcolile. Ungabangeli ukuhlanza ngaphandle uma uyalwe ochwepheshe bezokwelapha.

   
   

Kubalulekile ukuthi ubheke amashidi edatha yokuphepha (SDS) futhi uthobele izinkombandlela ezinikezwe umenzi noma iziphathimandla ezilawulayo lapho usebenza nge-oxalic acid.
