查询词典 oxalate

The score of renal calcium oxalate crystallization of 12%,25% medlar soak and apozem was reduced 38.7%, 54.8% and 48.4%, 58.1%(P.01) compared with the ethylene glycol drinking group.

The use of carbon monoxide from coal or natural gas to produce dialkyl oxalate is an important research area in C1 chemical technology. The chemical reactions and performance in the coupling reaction system for synthesis of diethyl oxalate from carbon monoxide and ethyl nitrite were tested in the presence of hydrogen under the typical coupling reaction conditions.

摘 要：实验研究了在氢气存在下，一氧化碳与亚硝酸乙酯偶联合成草酸二乙酯反应体系在典型操作条件下的化学反应和反应性能，结果表明氢气只与反应体系中的亚硝酸乙酯反应生成乙醇。

The investigated potassium carboxylates included: monocarboxylate potassium acetate, dicarboxylate potassium tartrate (K2Tart), tricarboxylate potassium citrate (K3Cit), and tetracarboxylate dipotassium of ethylenediaminetetraacetic acid (K2EDTA). KOAc can only induce calcium oxalate monohydrate, while K3Cit and K2EDTA induce COM and calcium oxalate dihydrate. The ability of multicarboxylates to induce COD formation was increased with increasing their concentrations.
