Nzira yeOxalic Acid yeEthylene Glycol Nitric Acid Oxidation
Maitiro aya ekuoxidation akafanana zvikuru nenzira yekuoxidation yestarch. Mhinduro ye ethylene glycol inodziiswa kusvika 60 °C, uye acid yakasanganiswa (30%–40% sulfuric acid nehuremu, 20%–25% nitric acid nehuremu) uye vanadium pentoxide zvinowedzerwa pasi pekukurunga kwakasimba. Kuoxidation kunoitwa pa50–70 °C uye 1.3–4.0 kPa. Chigadzirwa chinotonhodzwa, chinogadzirwa nekristaro, uye chinoseferwa kuti chiwane oxalic acid ine kuchena kwe99.9% uye goho rinodarika 90%. Nzira iyi inogona kuitwa pasi pemamiriro matatu ekuita: kumanikidzwa kwemhepo, kumanikidzwa kwakaderera, uye kumanikidzwa kwakawedzera. Ine maitiro ari nyore, goho repamusoro re oxalic acid, mhando yakanaka yechigadzirwa, uye kudzoreredzwa kwe nitric acid zvachose, asi mutengo wezvinhu zvakagadziriswa wakakwira.

Shandong Pulisi Chemical Co., Ltd. Oxalic Acid Dihydrate – 99.6% Chena yeMaindasitiri
Shandong Pulisi Chemical Co., Ltd., kambani inovimbwa nayo mukugadzira makemikari uye kutumira kunze kwenyika kubvira muna 2006, inonyanya kugadzira oxalic acid dihydrate (H₂C₂O₄·2H₂O, CAS 6153-56-6, EINECS 205-634-3) ine hunhu hwakanyanya. Oxalic acid yedu yepamusoro-soro ine hutsanana hwe99.6%, inoonekwa seupfu hwemakristaro machena husina kuchena kwakawanda (sulfate ≤0.1%, simbi dzinorema ≤0.002%, iron ≤0.003%). Inoshandiswa zvakanyanya mukudhinda nekudhaya machira, kugadzirisa dehwe, kuchenesa simbi pamusoro, kupukuta marble, kurapa mvura, kubvisa rare earth, uye kugadzira mishonga yemishonga.
Tinochengetedza zvinhu zvakawanda zviripo mudura redu reShandong, zvichiita kuti zvikwanisike kutumira zvinhu nekukurumidza. Sarudzo dzekutakura zvinhu dzinochinjika (25kg, 50kg, 1000kg mabhegi) uye kutumirwa kwenyika dzese kubva kuQingdao, Tianjin, kana Shanghai ports zvinovimbisa kutumirwa kwezvinhu nenguva pasi rose. Tinopa rutsigiro rwakazara rwehunyanzvi, magwaro eCOA/MSDS, uye mitengo inokwikwidzana kuti isangane nezvinodiwa zvakasiyana-siyana zvemaindasitiri.
Tibatei nhasi kuti muwane mutengo wakagadzirwa uye muchengetedze cheni yenyu ye oxalic acid.
