英语翻译
The production rate at 10 bar,-10 °C (Figure 4) is larger
with a small liquid flow rate.Recalling that productivity is
defined as the product of liquid flow rate times the outlet H2O2
concentration,its increase with smaller liquid flow rate implies
that the kinetics grows more than linearly with residence time.
Further,productivity varies with gas flow rate,always going
through a maximum,i.e.,an optimum gas flow rate can be
identified for every liquid flow rate examined.An optimum can
be identified with respect to liquid flow rate also.The maximum
production rate is measured with a small flow rate (0.5 mL/
min),but not the lowest tested (0.3 mL/min),implying a
nonlinear effect.
As discussed through the mechanism of Scheme 1,selectivity
due to the competing reactions is a major issue for direct
synthesis.Selectivity in the previous experiments is shown in
Figure 5.Again,the effect of both flow rates is dramatic,with
optimum selectivity at intermediate values.At small gas flow
rates the selectivity is always quite poor.The maximum
selectivity was achieved with liquid flow rates of 1 and 0.75
mL/min,but at correspondingly different gas flow rates.Note
that conditions for good production rate do not always match
those required for a high selectivity.

生产率在10bar, -10℃（图4）是一个较大的用小的液体流量.回顾生产率定义为液体流量的时间的乘积的出口H2O2浓度,其增加较小的液体流速意味着该动力学的增长超过线性的停留时间.
此外,产能与气体的流速不同,总是会通过一个最大值,即,最佳气体流速可以确定了检查每一个液体流速.一个最佳的罐头确定对于液体的流速也.最大产率是衡量一个小流量（ 0.5毫升/ 分钟）,但不是最低的测试（ 0.3毫升/分钟） ,相当于非线性效应.通过方案1中,选择性的机制讨论由于竞争反应是直接的重大课题合成.选择性在以前的实验中示出图5同样地,这两个流率的效果是显着的,具有最佳选择在中间值.在小型燃气流量率的选择性始终是相当差的.最大选择性为1和0.75的液体流速来实现毫升/分钟,但在相应的不同的气体流率.注对于良好的生产速率条件下并不总是匹配所要求的高选择性.
