Ụzọ Oxidation nke Ethylene Glycol Nitric Acid
Usoro oxidation a yiri nnọọ usoro oxidation starch. A na-ekpo ọkụ mmiri ethylene glycol ruo 60 °C, a na-agbakwụnyekwa acid agwakọtara (30%–40% sulfuric acid site na oke, 20%–25% nitric acid site na oke) na vanadium pentoxide mgbe a na-akpali ya nke ọma. A na-eme oxidation ahụ na 50–70 °C na 1.3–4.0 kPa. A na-eme ka ngwaahịa ahụ dị jụụ, na-agbanwe kristal, ma na-asacha ya iji nweta oxalic acid nke dị ọcha nke 99.9% na mkpụrụ karịrị 90%. Enwere ike ime usoro a n'okpuru ọnọdụ usoro atọ: nrụgide ikuku, mbelata nrụgide, na mmụba nrụgide. O nwere usoro dị mfe, nnukwu mmepụta oxalic acid, ezigbo mma ngwaahịa, na mgbake zuru oke nke nitric acid, mana ọnụ ahịa ihe eji emepụta ya dị elu.

Shandong Pulisi Chemical Co., Ltd. Oxalic Acid Dihydrate - Ọkwa ụlọ ọrụ mmepụta ihe 99.6% Ịdị ọcha
Shandong Pulisi Chemical Co., Ltd., ụlọ ọrụ mmepụta kemịkalụ a tụkwasịrị obi na mbupụ ya kemgbe afọ 2006, bụ ọkachamara n'ịmepụta oxalic acid dihydrate dị ọcha nke ukwuu (H₂C₂O₄·2H₂O, CAS 6153-56-6, EINECS 205-634-3) yana njikwa mma siri ike. Acid oxalic anyị nke ụlọ ọrụ mmepụta ihe nwere obere ịdị ọcha nke 99.6%, na-apụta dị ka ntụ ọcha kristal nwere obere adịghị ọcha (sulfate ≤0.1%, ọla dị arọ ≤0.002%, ígwè ≤0.003%). A na-etinye ya n'ọtụtụ ebe na mbipụta ákwà na agba agba, nhazi akpụkpọ anụ, nhicha elu ígwè, ịchacha marble, ọgwụgwọ mmiri, mwepụ ala dị ụkọ, na mmepụta ọgwụ.
Anyị na-echekwa nnukwu ngwa ahịa dị n'ụlọ nkwakọba ihe anyị na Shandong, nke na-eme ka e nwee ike izipu ngwa ngwa maka iwu buru ibu.
