Mashandisirwo eOxalic Acid mukudhinda nekugadzira machira

Mashandisirwo e Oxalic Acid
Muindasitiri yemakemikari, oxalic acid inoshandiswa kugadzira pentaerythritol, cobalt oxalate, nickel oxalate, basic fuchsin, complete reagent kits dzekuongorora simbi nevhu, chemical reagents, nezvimwe zvigadzirwa.
Mukukurumidza kudhaya, inoshanda sechinhu chinogadzira ruvara uye chinoenzanisa.
Inoshanda semushonga wekuchena kwezvishandiso zvehuswa negorosi (inoshandisa simba rekuderedza oxalic acid) uye semushonga wekubvisa ngura (oxalic acid inosangana nesimbi kuti igadzire soluble iron oxalate, iyo inosukurudzwa nyore nyore nemvura, nokudaro ichibvisa mavanga esimbi kubva mumachira).
Mashandisirwo eOxalic Acid mukudhinda nekugadzira machira
(1) Kubvisa Mavara Engura Pamachira
Kana simbi yasangana neokisijeni nehunyoro mumhepo, inoumba chinhu chakaoma chinonzi ngura. Kunyange zvazvo chimiro chaicho chichisiyana zvichienderana nemamiriro ekuumbwa, ngura yese ine maion esimbi ane trivalent. Mavara engura pamicheka yedonje anoumba zvikanganiso zvinogara zviripo zvinofanira kubviswa, uye oxalic acid inobatsira zvikuru pakubvisa zvikanganiso izvi. Pfungwa yacho ndeyekuti oxalic acid inosangana nemaion esimbi ane trivalent (Fe³⁺) kuti igadzire soluble anionic complex ion, [Fe(C₂O₄)₃]³⁻, iyo inonyungudika nyore nyore mumvura. Kazhinji inoshandiswa i20 g/L ye oxalic acid ine inenge 30 mL/L ye 98% acetic acid.
Zvakakosha: Oxalic acid inogona kukuvadza machira. Mushure mekurapwa, machira edonje anofanira kusukurudzwa zvakanaka nemvura yakachena kuti abvise machira ese asara eoxalic acid. Kana akasasukurudzwa zvakanaka, oxalic acid inosanganiswa nemvura inenge yaoma, zvichikonzera kukuvara kukuru kwefiber uye kugadzira maburi.
Oxalic acid inogonawo kubvisa mavara engura kubva mumachira enylon, izvo zvaizokonzera yero.
(2) Kubvisa Nitrous Acid Gas Panguva Yekugadzirwa Nemadhayi EIngrain
Pakushandisa nzira ye sodium nitrite yekudhinda zvakananga ne ingrain dyes pamwe chete ne naphthol dyes, nitrous acid inogadzirwa panguva yekukura kwe sulfuric acid. Izvi zvinoita kuti naphthol AS sodium salts pajira igadzire ma precipitates matsvuku-brown, zvichikonzera kusaenzana kwemavara machena. Kuti nitrous acid ibviswe, 1–2 g/L ye oxalic acid dzimwe nguva inowedzerwa mumushonga wekugadzira sulfuric acid se reducing agent (inotsiva formic acid, urea, kana sulfur). Oxalic acid inoderedza nitrous acid kuita nitrogen gas, ichidzivirira HNO₂ kuti isaite ne AS kuti igadzire brown compounds.
