Hanyar Oxidation na Ethylene Glycol Nitric Acid
Wannan tsarin hadawa yana kama da hanyar hadawa da sitaci. Ana dumama ruwan ethylene glycol zuwa digiri 60 na Celsius, sannan a kara hadadden acid (30%–40% sulfuric acid ta hanyar taro, 20%–25% nitric acid ta hanyar taro) da kuma vanadium pentoxide a lokacin da ake juyawa da karfi. Ana yin hadawa da iskar shaka a digiri 50–70 na Celsius da 1.3–4.0 na kPa. Ana sanyaya samfurin, a tace shi, sannan a tace shi don samun sinadarin oxalic acid mai tsarkin kashi 99.9% da kuma yawan amfanin da ya kai kashi 90%. Ana iya aiwatar da wannan hanyar a karkashin yanayi uku: matsin lamba a yanayi, rage matsin lamba, da kuma karuwar matsin lamba. Yana da tsari mai sauki, yawan sinadarin oxalic acid, ingancin samfur mai kyau, da kuma kusan cikakken murmurewa na sinadarin nitric acid, amma farashin kayan yana da yawa.

Kamfanin Shandong Pulisi Chemical Co., Ltd. Oxalic Acid Dihydrate – Tsarkakewar Masana'antu 99.6%
Kamfanin Shandong Pulisi Chemical Co., Ltd., wanda aka amince da shi wajen kera sinadarai kuma ake fitarwa tun daga shekarar 2006, ya ƙware wajen samar da sinadarin oxalic acid mai yawan tsarki (H₂C₂O₄·2H₂O, CAS 6153-56-6, EINECS 205-634-3) tare da ingantaccen kula da inganci. Sinadarin oxalic acid ɗinmu na masana'antu yana da mafi ƙarancin tsarkin kashi 99.6%, yana bayyana a matsayin farin foda mai ƙarancin ƙazanta (sulfate ≤0.1%, ƙarfe mai nauyi ≤0.002%, ƙarfe ≤0.003%). Ana amfani da shi sosai a bugu da rini a yadi, sarrafa fata, tsaftace saman ƙarfe, goge marmara, maganin ruwa, cire ƙasa mai wuya, da kuma haɗa magunguna.
Muna da tarin kayayyaki masu yawa a cikin rumbun ajiyar mu na Shandong, wanda ke ba da damar aika da kayayyaki nan take don yin oda mai yawa. Zaɓuɓɓukan marufi masu sassauƙa (jakunkuna 25kg, 50kg, 1000kg) da jigilar kaya daga tashoshin jiragen ruwa na Qingdao, Tianjin, ko Shanghai suna tabbatar da isar da kayayyaki cikin lokaci a duk duniya. Muna ba da cikakken tallafin fasaha, takaddun COA/MSDS, da farashi mai gasa don biyan buƙatun masana'antu daban-daban.
Tuntube mu a yau don samun farashi na musamman da kuma tabbatar da sarkar samar da sinadarin oxalic acid ɗin ku.
