查询词典 toluic acid

Furthermore, benzoic acid, p-toluic acid and p-phthalic acid were transformed slowly in sediment slurries amended with BESA (20 mM) under the condition of 100% CO2 and H2/CO2 (20/80), respectively, and the sediment slurry was dominated by methanogene bacteria.

在底泥含有甲烷菌抑制剂及上层气体分别为100% CO2和H2/CO2 (20ml/80ml)时，苯甲酸、对位甲基苯甲酸及对位苯二酸之分解变慢，且此底泥菌群是以甲烷菌为主要优势菌。

Keywords p -toluic acid;solubility;laser monitoring technique

对甲基苯甲酸；溶解度；激光监视技术

The effects of the reaction temperature , time ,pressure and air flow on the vield of o - toluic acid were evaluated on a medium sized Semi - coninuous bubbling bed reartor.

The range of bacteria that could be effectively detected corresponded to about 10^4 to 5×10^5 cells/mL. Results obtained, using a medium with toluic acid as the sole carbon source, indicated that in soil either with, or without, the addition of toluene, P. putida D8 could not be recovered, 288 and 72 hours after inoculation, using classical growth-dependent culture techniques.

根据传统之平板培养法，利用toluic acid为唯一碳源之选择培养基，侦测Pseudomonas putida D8在土壤中之消长情形，结果显示在有添加甲苯之状况下到188小时后方才无法测得目标菌株；反之，在没有添加甲苯的情况下，48小时后便已无法测得。

This paper investigates that the different composition of the headspace gas and polluted sediment slurries can affect the ratios of degradation on benzoic acid, toluic acid and phthalic acid isomers. We found that a sediment slurry which has been polluted can develop a stronger microbial degradation.

此篇文章主要是探讨不同上层气体之组成和被污染过之底泥可影响苯甲酸、甲基苯甲酸异构物及苯二酸异构物被分解的速率，我们发现被污染过之底泥可发展出较强之微生物降解力。

A method of preparing o - toluic acid from o - xylene with air as oxidiaing agent, cobalt naphthenate as catalyst by liquid - phase oxidation was introduced.

介绍了采用空气作氧化剂、环烷酸钴作催化剂，由邻二甲苯液相氧化制备邻甲苯甲酸的方法。

Because of the bonded crown ring the catalytic activity of complexes can be improved and the induce period of the oxidation for p-xylene to p-toluic acid was shortened from～ 10h to 0.5～5h, the fashion and position of the bonded crown ring as well as the distance between the crown ring and activity center have distinct influence on the catalytic activity of complexes.

结果表明：1。键连的冠醚环均能显著提高催化活性，并大大缩短反应诱导期5-10h，使TOF从21～60提高到152～222，约增加了5～7倍；冠环的键连方式和部位以及与活性中心的距离对催化活性影响明显；2。

Phthalic acid and o-toluic acid were made with sacrificial anode method.
