Ko te waikawa Oxalic he matū waro me te tauira matū H₂C₂O₄.He metabolite o nga rauropi ora.He waikawa ngoikore dibasic.Ka tohatohahia i roto i nga tipu, nga kararehe me nga harore, he rereke nga mahi i roto i nga momo rauropi.Ko tana waikawa anhydride he waro trioxide.Ko te ahua o te waikawa oxalic he tawerewere monoclinic kore tae, he karaihe prismatic ranei he paura ma, he kakara, he reka kawa, he ngawari ki te wai engari kare e memeha i roto i nga whakarewa pararopi penei i te ether.Ko te taumaha ngota o te waikawa oxalic he 90.0349.
Whakamahinga o te waikawa oxalic: te kai whakawhäiti, te kaikawe huna, te kaikawe whakaheke, te kaihoko whakaheke.
1, hei kai whakapoi
Ko te waikawa Oxalic te nuinga o te whakamahi hei kaihoko whakaheke me te kaihoko whakapoipoi, whakamahia i roto i te hanga o nga raau taero penei i te paturopi me te borneol, hei whakarewa mo te tangohanga o nga konganuku onge, hei kaihoko whakaheke waikano, hei kaihoko tanning.
Ka whakamahia ano te waikawa Oxalic i roto i te hanga o nga whakakorikori cobalt-molybdenum-konumohe, te horoi o nga konganuku me te mapere, me te whakamaarama o nga kakano.
2. Hei kaihoko whakaiti
I roto i te ahumahi whakahiato waro, ka whakamahia te nuinga ki te whakaputa hua matū penei i te hydroquinone, pentaerythritol, cobalt oxalate, nickel oxalate, me te waikawa gallic.
Ka whakamahia te ahumahi kirihou i roto i te hanga o te polyvinyl chloride, aminoplastics, kirihou urea-formaldehyde, pepa lacquer, etc.
Ka whakamahia te ahumahi waikano ki te hanga i te magenta kakariki, aha atu.
I roto i te ahumahi tā me te waikano, ka taea te whakakapi i te waikawa acetic ka whakamahia hei awhina whakahiato tae me te kai whakapoi mo nga waikano poaka.
whakamahia te ahumahi ho'oraa i roto i te hanga o chlortetracycline, oxytetracycline, tetracycline, streptomycin, me te ephedrine.
I tua atu, ka taea hoki te whakamahi i te waikawa oxalic ki te whakahiato i nga momo hua penei i te oxalate, oxalate me te oxalamide, kei roto ko te diethyl oxalate, te konutai oxalate me te konupūmā oxalate te tino whai hua.
3. Hei momona
Ka taea te whakamahi i te Antimony oxalate hei mordant, a ko te ferric ammonium oxalate he kaihoko mo te tuhi i nga mahere.
4 Te mahi tango waikura
Ka taea te whakamahi i te waikawa Oxalic ki te tango waikura: hokona he pounamu waikawa oxalic mai i te toa e hoko ana i nga reagents matū, tangohia etahi, hanga he otinga ki te wai mahana, pania ki te waikura ka horoia.(Tuhipoka: Kia tupato i te wa e whakamahi ana, he tino pirau te waikawa oxalic ki te kowiri tira. Ko te waikawa oxalic me te kukū teitei he ngawari hoki te weriweri i nga ringaringa. A ko te waikawa oxalate i hangaia he tino wairewa, engari he ahua paitini. Kaua e kai. ina whakamahi 。 Ka pa ana te kiri ki te waikawa oxalic, me horoi ki te wai i te wa.)
Te rokiroki waikawa Oxalic
1. Rokiroki ki te wahi maroke me te hauhautanga.He tino makuku, he parewai, he parepare ra.Ko te pāmahana rokiroki kaua e neke ake i te 40 ℃.
2. Kia matara atu i nga waikura me nga matū kawakore.Ka mau ki roto i te putea raranga polypropylene kua kapi ki te peeke kirihou.
