查询词典 oxidation process

The oxidation of methyl linoleate was inhibited by β-carotene, lutein and bixin in a dose-dependent manner. Lutein and zeaxanthin suppressed the hydroperoxide formation more efficiently than β-carotene and bixin at 41.7×10-6mol/L. Lutein inhibited the oxidation of methyl linoleate as efficiently as zeaxanthin.

Addition of 10 % fresh Boehmeria nivea root into XO paste for 28 days under 50℃, the POV value was 24.33± 1.33 meq/kg, which is smaller than that of control samples(32.40 ±0.53 meq/kg), indicating an ability to decrease the rate of oil oxidation. However, with the addition of 10% of fresh leaf to XO paste, oil oxidation was promoted instead.

添加10 %的新鲜苎麻根於XO酱中，在贮存50℃下28天时，其POV值为24.33 ±1.33 meq/kg，较对照组(32.40 ±0.53 meq/kg)低，显示添加10 %新鲜苎麻根於XO酱中可延缓油脂氧化的速率，但添加10 %新鲜苎麻叶於XO酱中反而促进油脂氧化。

板框式电化学反应器，由于具有结构紧凑、体积电流密度大、槽压低等优点，而被广泛应用于电化学工业中，例如，离子膜氯碱合成工业、有机电合成工业中的己二腈电合成、间接电氧化合成维生素K_3等均选用了板框式电化学反应器。

The results of in situ DRIFTS on propylene oxidation show that the allyl species originated from α-H abstraction of propylene were located at the wavenumbers of 1454 cm~(-1) and 1427 cm~(-1). The rate-determining step is the abstraction of an α-H abstraction from a lattice oxygen linked to a bismuth ion to form a π-allyl intermediate coordinated to a molybdenum ion. The metal-oxo group then attacks the allyl intermediate forming a σ-bonded oxygen-allyl species, which is in a rapid equilibrium with the π- bonded species. The σ-bonded species then transforms to acrolein by further abstraction of α-H. Such species as formate, carboxylate, carbonate transform to deep oxidation products. The acetone was derived from propylene by an enolic species at lower temperatures.

丙烯氧化反应体系的原位漫反射红外光谱研究结果表明，由丙烯脱氢生成的烯丙基中间物种吸收峰在1454cm~(-1)和1427cm~(-1)处；基于此提出了较完整的丙烯氧化反应网络：丙烯选择氧化生成丙烯醛主要经历丙烯脱除甲基上的一个H，生成烯丙基物种，该物种嵌氧生成σ-O络合物，脱氢得到丙烯醛前驱体，脱附生成丙烯醛；完全氧化产物是由催化剂表面上生成甲酸盐、羧酸盐、碳酸盐等形式的中间物种转化而成；较低反应温度下丙烯氧化生成丙酮，通过烯醇式中间物种氧化生成丙酮前驱体得到。
