Dibenzyl oxalate was synthesized from oxalic acid, potassium hydroxide and benzyl bromide under microwave irradiation using tetrabutylammonium bromide as phase-transfer catalyst and polyethylene glycol-200 as solvent.

在微波辐射条件下，以草酸、氢氧化钾和溴化苄为原料，四丁基溴化铵为相转移催化剂，聚乙二醇200为溶剂合成了草酸二苄酯，并通过熔点和红外光谱对产物的结构进行了表征。

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.

加入一元醋酸钾只生成一水草酸钙晶体；三元柠檬酸钾(K3Cit)和四元乙二胺四乙酸二钾(K2EDTA)可诱导二水草酸钙形成，且随着其浓度增加，对COD的诱导能力增加，而二元酒石酸钾(K2Tart)同时诱导了COM， COD和三水草酸钙生成。

The amount of bacteria in cuhure was detected, the concentration of ammonium oxalate was detected through photometric determination of oxalic acid by its catalytic reaction of methyl red by potassium chromate.

经过72h培养，所有培养基中的草酸浓度都有不同程度的下降，但乳酸菌组的降幅明显大于对照组，其中嗜酸乳杆菌组的降幅最大。

The procedure is based on the inhibiting effect of ascorbic acid on the enhancing effect of oxalate on the potassium dichromate-potassium iodide／rhodamine6G system.

基于在硫酸介质中，抗坏血酸对草酸根加速重铬酸钾－碘化钾/罗丹明6G这一反应体系具有抑制作用，建立了动力学抑制光度法测定抗坏血酸的新方法。

I will endeavour to find you some assistance.
