Kodi pali kusiyana kotani pakati pa oxalic acid ndi calcium? Acetic Acid?
Kuti tisiyanitse oxalic acid ndi acetic acid, tingawayerekezere kuchokera ku zinthu zosiyanasiyana monga chilengedwe cha mankhwala, makhalidwe ake, ndi ntchito zake. Ngakhale kuti zonsezi ndi za ma organic acid, kusiyana kwa kapangidwe kake ndi makhalidwe ake kumabweretsa kusiyana kwakukulu kwa makhalidwe m'chilengedwe, momwe mankhwala amachitira, komanso momwe anthu amagwiritsira ntchito.

Choyamba, tiyeni tiwone kapangidwe kake ka mankhwala.
Oxalic acid, yomwe imadziwika kuti ethanedioic acid, ili ndi magulu awiri a carboxyl (-COOH) mu kapangidwe kake ka molekyulu, yokhala ndi formula ya molekyulu H₂C₂O₄. Ili ngati molekyulu yonyamula magulu awiri a acidic, yokonzeka kutulutsa ma ayoni awiri a hydrogen.

Acetic acid, yomwe imadziwikanso kuti ethanoic acid, ili ndi gulu limodzi lokha la carboxyl, yokhala ndi formula ya molekyulu ya CH₃COOH. Molekyulu yake ili ngati "woyenda payekha" wokhala ndi gulu limodzi la acidic. Kusiyana kumeneku mu kapangidwe ka mamolekyulu, mofanana ndi "majini awo", kumatsimikizira kusiyana kwa makhalidwe komwe kumachitika pambuyo pake.

Kuwonekera kwachindunji kwa "kusiyana kwa majini" kumeneku ndi mphamvu ya asidi.
Oxalic acid ndi diprotic strong acid yomwe imatha kuionitsa ma hydrogen ions pang'onopang'ono mu yankho lamadzi, zomwe zimapangitsa kuti acidity yake ikhale yolimba kwambiri kuposa ya acetic acid.

Asidi ya Acetic ndi asidi wofooka wamba wa monoprotic; mamolekyu ake ena okha ndi omwe amasungunuka m'madzi, zomwe zimapangitsa kuti asidi akhale wofatsa.
Tikhoza kuganiza za oxalic acid ngati wachinyamata wamphamvu komanso wochita zinthu mwachangu, pomwe acetic acid ili ngati munthu wofatsa komanso wodziletsa.

Ponena za mphamvu zake za mankhwala, chifukwa cha kugwirizana kwa magulu awiri a carboxyl, oxalic acid imatha kuchepetsedwa kwambiri. Imasungunuka mosavuta ndi zinthu zopangitsa kuti oxygen ikhale yochuluka (monga potaziyamu permanganate) kuti ipange carbon dioxide ndi madzi. Khalidweli limapangitsa kuti oxalic acid igwiritsidwe ntchito kwambiri ngati chochepetsera mankhwala.

Mosiyana ndi zimenezi, kapangidwe ka mamolekyu a acetic acid ndi kokhazikika, nthawi zambiri sikumasungunuka mosavuta, zomwe zimapangitsa kuti ikhale ndi mankhwala "okhazikika".
Kuphatikiza apo, pamene oxalic acid imagwirizana ndi ma ayoni ena achitsulo (monga ma ayoni a calcium), imapanga ma calcium oxalate precipitates omwe sangasungunuke bwino m'madzi, omwe ndi amodzi mwa zigawo zazikulu za miyala ya impso.
Poyerekeza, ma acetates opangidwa ndi momwe acetic acid imagwirira ntchito ndi ma calcium ions ndi zinthu zina nthawi zambiri amasungunuka mosavuta m'madzi.

Ponena za zochitika ndi ntchito, chilichonse chili ndi cholinga chake.
Oxalic acid imapezeka kwambiri m'zomera zambiri zachilengedwe, monga sipinachi, amaranth, ndi rhubarb. Ichi ndichifukwa chake tikulimbikitsidwa kutsuka ndiwo zamasamba izi musanazigwiritse ntchito kuti tichotse gawo la oxalic acid. Imagwiritsidwa ntchito m'mafakitale osiyanasiyana, kuphatikizapo kuchotsa dzimbiri, kuyeretsa nsalu, komanso kulekanitsa ndi kuyeretsa zitsulo zosadziwika bwino. Komabe, chifukwa cha poizoni wake komanso kuwonongeka kwake, muyenera kusamala kwambiri mukamagwiritsa ntchito.

Asidi ya acetic ndi imodzi mwa ma asidi achilengedwe odziwika bwino kwambiri pa moyo watsiku ndi tsiku. Ndi gawo lalikulu la viniga, zomwe zimapangitsa viniga kukhala ndi kukoma kwake kowawasa. Mumakampani opanga chakudya, asidi ya acetic imagwiritsidwa ntchito ngati asidi komanso chosungira; mumakampani opanga mankhwala, ndi chinthu chofunikira kwambiri chopangira zinthu zachilengedwe popanga vinyl acetate, ulusi wa acetate, ndi zina zambiri. Chifukwa cha asidi wofatsa komanso poizoni wochepa kwambiri (mkati mwa kuchuluka koyenera kugwiritsidwa ntchito), asidi ya acetic imagwiritsidwa ntchito kwambiri komanso mosamala m'magawo azakudya ndi mankhwala.

Oxalic Acid – Zibo Anhao Chemical Co., Ltd.
Zibo Anhao Chemical Co., Ltd. ndi kampani yodalirika yaku China yopanga komanso yogulitsa oxalic acid yapamwamba kwambiri (Ethanedioic Acid, CAS 144-62-7), yomwe ili ku Zibo, Shandong—malo ofunikira kwambiri pamakampani opanga mankhwala ku China. Oxalic acid yathu imapezeka mu mtundu wa anhydrous (≥99.5%) ndi dihydrate (≥99.0%), yomwe imawoneka ngati ufa woyera wa kristalo wokhala ndi mankhwala okhazikika, chinyezi chochepa, komanso zodetsa zochepa.

Oxalic acid yathu, yopangidwa motsatira malamulo okhwima a khalidwe ndi miyezo ya dziko, ili ndi mphamvu yochepetsera kwambiri komanso luso labwino kwambiri lochotsa utoto, imagwiritsidwa ntchito kwambiri popaka utoto wa nsalu (mordant/bleaching), kukonza zitsulo (kuchotsa dzimbiri/electroplating), kuchotsa nthaka yachilendo, kupanga zinthu zachilengedwe, kupukuta khungu, komanso kupanga mankhwala ndi agrochemical. Gulu lililonse limayesedwa mokwanira ndipo limatsatiridwa ndi COA, MSDS, ndi zikalata zina zotsatizana kuti zikwaniritse zofunikira za mafakitale padziko lonse lapansi.

Ndi zaka zambiri zokumana nazo zotumiza kunja ku Asia, Europe, Middle East, ndi kwina, timapereka ma phukusi osinthika (matumba 25kg), mitengo yopikisana, komanso nthawi yotumizira yodalirika (FOB/CIF/DDP). Kaya ndi maoda ang'onoang'ono oyesera kapena operekedwa ambiri, Zibo Anhao Chemical imapereka mayankho abwino komanso okhazikika, komanso okonzedwa bwino kuti athandize kukula kwa bizinesi yanu.
