Results The data of A were higher in 0.5%, 1%, 2% erythritol culture medium than in xylitol culture medium at the same concentration, while lower in 8%, 12%, 16% erythritol culture medium than in xylitol culture medium at the same concentration. The data of pH were lower in 0.5%, 1%, 2% erythritol culture medium than in xylitol culture medium at the same concentration, while higer in 8%, 12%, 16% erythritol culture medium than in xylitol culture medium at the same concentration.

结果 在0.5%、1%、2%浓度下,赤藓糖醇培养基的A值较木糖醇培养基高,pH值较木糖醇培养基低,说明变异链球菌在含0.5%、1%、2%赤藓糖醇的培养基内的生长和产酸能力明显较相同浓度木糖醇培养基高。

The new aproach of which can be achieved via the oxidation of 2-naphthylamine (39) by CuCl〓benzylamine or ethanolamine (2: 1) in methanol under mild condition with isolated yield up to 74%.

本文开发出利用2-萘胺(39)为原料,以氯化铜—苄胺或乙醇胺(2:1)作为氧化偶合试剂,在温和的条件下和甲醇溶剂中,以高达74%的产率合成40的新方法。

Influened the synthesis of ferrocene by the sodium ethylate method were researched in this paper.

研究了乙醇钠法合成二茂铁的影响因素:不同原料、原料配比、温度、时间、反应体系的氛围等,在选定的较优条件下,三茂铁的产率达到81.3%,并对二茂铁在柴油中的助燃、消烟作用进行了初步考察。

After esterification, the ethyl-2-chloro-3-phenylpropionate reacts with diethyl malonate under the catalysis of sodium ethylate, and we obtain the corresponding triethyl ester. The-benzylsuccinic acid is formed by the triethyl ester reacting with concentrate hydrochloric acid and taking place hydrolyzation and decarboxylation reaction at the same time. In order to avoid the formation of cinnamic acid, the sodium ethylate and diethyl malonate must be react sufficiently. The course has simple operation, inexpensive materials and better yield.

具体制备工艺为:首先以L-苯丙氨酸为原料采用重氮化方法得到-2-氯-3-苯基丙酸,再经酯化得到-2-氯-3-苯基丙酸乙酯后在乙醇钠催化作用下和丙二酸二乙酯缩合,发生SN2反应,得到相应的三乙酯,然后经水解和脱羧,得到-苄基丁二酸;在实验中乙醇钠要和丙二酸二乙酯充分反应,避免生成肉桂酸乙酯;该过程操作简单,原料便宜,产率较高,总收率可达到26.8%。

Expectedly, catalysis by a proper microbial consortium at the MFC anode was also critical to this study.

MFC在适合的管径条件下可以高效去除苯酚的同时,能有较高的产电效率;MFC的阳极反应需要微生物的催化。
