ʻOxalic Acid

wehewehe pōkole:

He ʻano ʻakika organik, he huahana metabolic o nā mea ola, binary acid, laha nui ʻia i nā mea kanu, nā holoholona a me nā haʻani, a ma nā mea ola like ʻole e pāʻani i nā hana like ʻole.Ua ʻike ʻia ka waiwai o ka oxalic acid ma mua o 100 mau ʻano mea kanu, ʻoi aku ka spinach, amaranth, beet, purslane, kalo, ʻuala a me ka rhubarb.No ka mea hiki i ka oxalic acid ke hōʻemi i ka bioavailability o nā mea mineral, ua manaʻo ʻia he antagonist no ka absorption a me ka hoʻohana ʻana i nā mea mineral.ʻO kona anhydride he carbon sesquioxide.

mea hoʻohui kala

I ka ʻoihana paʻi a me ka hoʻoluʻu ʻana, hiki iā ia ke pani i ka acetic acid e hana i nā kala kumu.Hoʻohana ʻia ma ke ʻano he kala a me ka bleach no nā kala puaʻa.Hiki ke hoʻohui ʻia me kekahi mau mea kemika e hana ai i nā mea pena, a hiki ke hoʻohana ʻia ma ke ʻano he stabilizer no nā kala, a laila e hoʻolōʻihi i ke ola o nā wai.

Mea hoʻomaʻemaʻe

ʻO ka hoʻohanaʻana i ka zeolite ma keʻano he mea hoʻopihapiha i kaʻoihana pepa e hiki ke hoʻonui i ka hana a me ka maikaʻi o ka pepa, i mea e hoʻonui ai kona porosity, hoʻonuiʻia ka wai,ʻoi aku ka maʻalahi o kaʻokiʻana, hoʻomaikaʻiʻia ka hana kākau, a loaʻa iā ia kekahi mau pale ahi.

ʻoihana palaki

ʻO ka ʻoihana plastik no ka hana ʻana i ka polyvinyl chloride, nā plastik amino, nā plastik urea formaldehyde, nā ʻāpana pena a pēlā aku.

ʻoihana photovoltaic

Hoʻohana pū ʻia ka waikawa Oxalic i ka ʻoihana photovoltaic.Hiki ke hoʻohana ʻia ka ʻakika oxalic e hana i nā wafer silika no nā panela lā, e kōkua ana e hōʻemi i nā hemahema ma ka ʻili o nā wafer silika.

Ka holoi ʻana i ke one

Hiki i ka waika Oxalic i hui pū ʻia me ka waikawa hydrochloric a me ka waika hydrofluoric ke hana i ka holoi ʻana i ka waika o ke one quartz.

Synthesis catalyst

Ma ke ʻano he catalyst no ka phenolic resin synthesis, ʻoluʻolu ka hopena catalytic, paʻa ke kaʻina hana, a ʻo ka lōʻihi ka lōʻihi.Hiki i ka Acetone oxalate solution ke hoʻopau i ka hopena o ka epoxy resin a hoʻopōkole i ka manawa hoʻōla.Hoʻohana ʻia ia ma ke ʻano he pH regulator no ka synthesis o ka resin urea-formaldehyde a me ka resin formaldehyde melamine.Hiki ke hoʻohui ʻia i ka wai-soluble polyvinyl alcohol adhesive e hoʻomaikaʻi i ka wikiwiki maloʻo a me ka ikaika paʻa.Hiki ke hoʻohana ʻia e like me ka lāʻau lapaʻau o ka resin urea-formaldehyde a me ka mea hoʻoheheʻe ion metala.Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻolalelale no ka hoʻomākaukau ʻana i ka mea hoʻopaʻa starch me ka KMnO4 oxidizing agent e wikiwiki i ka oxidation rate a hoʻopōkole i ka manawa pane.
