Habka Oxidation-ka ee Acid-ka Oxalic ee Ethylene Glycol
Habkan oksaydheynta wuxuu aad ugu eg yahay habka oksaydhka istaarijka. Xalka ethylene glycol ee biyaha lagu kululeeyo ayaa lagu kululeeyaa 60 °C, aashitada isku dhafan (30%–40% sulfuric acid cuf ahaan, 20%–25% nitric acid cuf ahaan) iyo vanadium pentoxide ayaa lagu daraa walaaq xooggan. Oksaydhka waxaa lagu sameeyaa 50–70 °C iyo 1.3–4.0 kPa. Badeecada waa la qaboojiyaa, la sifeeyaa, oo la sifeeyaa si loo helo oxalic acid oo leh daahirnimo 99.9% iyo wax soo saar ka badan 90%. Habkan waxaa lagu samayn karaa saddex xaaladood oo habka ah: cadaadiska jawiga, cadaadiska oo yaraada, iyo cadaadiska oo kordha. Waxay leedahay hab fudud, wax soo saar sare oo oxalic acid ah, tayo wanaagsan oo badeecad ah, iyo ku dhawaad ​​​​soo kabasho dhammaystiran oo nitric acid ah, laakiin qiimaha alaabta ceeriin ah waa sarreeyaa.

Shandong Pulisi Chemical Co., Ltd. Oxalic Acid Dihydrate - Nadiifin Sare 99.6% ah
Shirkadda Shandong Pulisi Chemical Co., Ltd., oo ah soo-saare kiimiko oo la aamini karo iyo dhoofiye tan iyo 2006, waxay ku takhasustay soo saarista aashitada oxalic dihydrate saafi ah oo sare (H₂C₂O₄·2H₂O, CAS 6153-56-6, EINECS 205-634-3) iyadoo la ilaalinayo tayada adag. Aashitada oxalic-ga ee heerka warshadaha waxay ku faantaa daahirnimo ugu yaraan 99.6%, iyadoo u muuqata budo cad oo crystalline ah oo leh heerar wasakh yar (sulfate ≤0.1%, biraha culus ≤0.002%, birta ≤0.003%). Waxaa si weyn loogu isticmaalaa daabacaadda dharka iyo rinjiyeynta, farsamaynta maqaarka, nadiifinta dusha sare ee birta, nadiifinta marmarka, daaweynta biyaha, soo saarista dhulka naadirka ah, iyo isku-darka dhexdhexaadka ah ee dawooyinka.
Waxaan ku haynaa kayd aad u badan bakhaaradayada Shandong, taasoo suurtogalinaysa in si degdeg ah loo diro dalabaadka badan. Xulashooyinka baakadaha dabacsan (25kg, 50kg, 1000kg bacaha) iyo rarista caalamiga ah ee ka timaadda dekedaha Qingdao, Tianjin, ama Shanghai waxay hubinayaan in si degdeg ah loo keeno adduunka oo dhan. Waxaan bixinnaa taageero farsamo oo buuxda, dukumentiyada COA/MSDS, iyo qiimo tartan ah si loo daboolo baahiyaha warshadaha ee kala duwan.
