Abstract
It was determined that RuCl2(PPh3)3 obtained with a modified method described by Shaw’s group (Shaw et al., 2007) had the best catalytic properties in the reaction performed under conditions described in Liang Wang’s publication (Wang et al., 2014). It was also determined that for concentration ratio of substrate to RuCl2(PPh3)3 amounting to 250:1 the conversion rate was much higher than that of the reaction performed with a double dose of the catalyst. Results of experiments also show that samples of the post-reaction solution should be analyzed right after the reaction, because even if they are stored in low temperature the amount of product can change up to 3–5% compared to the base sample and this change is not predictable.
在Wang Liang发表的文章(Wang et al.， 2014)所描述的条件下进行的反应中，通过Shaw 's group (Shaw et al.， 2007)描述的改进方法获得的RuCl2(PPh3)3具有最佳的催化性能。实验还发现，当底物与RuCl2(PPh3)3的浓度比为250:1时，转化率远高于催化剂用量为两倍时的转化率。实验结果还表明，反应后溶液的样品应在反应后立即进行分析，因为即使将其保存在低温下，与基础样品相比，产物的量也可能变化3-5%，这种变化是不可预测的。
期刊介绍：
The content, aim and scope of the proposals should comply with the main subject of the journal, i.e. they should deal with mathematical modelling and/or experimental investigations on momentum, heat and mass transfer, unit processes and operations, integrated processes, biochemical engineering, statics and kinetics of chemical reactions. The experiments and modelling may cover different scales and processes ranging from the molecular phenomena up to production systems. The journal language is grammatically correct British English.
Chemical and Process Engineering publishes: i) full text research articles, ii) invited reviews, iii) letters to the editor and iv) short communications, aiming at important new results and/or applications. Each of the publication form is peer-reviewed by at least two independent referees.
