查询词典 dicarboxylate

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。

Therefore, C_4-dicarboxylate transport system may also play an important role in gluconeogenesis of phytopathogenic bacteria.

在野油菜黄单胞菌野油菜致病变种8004菌株(Xcc 8004)基因组的功能注释中存在dctA、dctP和dctQ。

Bromo-5-formyl -3-methylpyrrole is an important intermediate of tolyporohin. On the base of introducing the present research and development of tolypo- rohin and pyrroles ramification at home and abroad, an emphasis was made on synthesis of 2-Bromo-5-formyl -3-methylpyrrole and the technical conditions of all steps, which was described as follows. Diethyl 3,5-dimethylpyrrole-2,4-dicarboxylate was made by nitrification, reduction and cycle of ethyl acetoacetate.

由于2-溴-5-甲酰基-3-甲基吡咯是合成托尼卟吩的重要中间体，本文在阐述了当前托尼卟吩及吡咯衍生物的国内外研究和开发的基础上，重点研究了2-溴-5-甲酰基-3-甲基吡咯的合成，并对各步反应进行了工艺研究，具体合成步骤如下：本文通过对乙酰乙酸乙酯的亚硝化、还原、成环，反应生成吡咯单环衍生物2，4-二乙氧羰基-3，5-二甲基吡咯。
