It is of interest to know whether the ion-exchanged metal
could leach out from the zeolite pore.Leaching experiment for
hydroxylation of phenol performed using OV–Y catalyst as a
representative catalyst.The catalyst was recovered by filtration,
regenerated by soxhlet extraction (MeCN),dried at 150 8C for 6 h
and reused several times.It was found that the metal leached \22%
which may be due to leaching of the remaining metal ions on the
surface.Leaching was lowered markedly after the first reuse and
almost stopped after the second cycle.The % conversion was
lowered by 2–3% but reserved its selectivity (Fig.8).
It is of interest to know whether the ion-exchanged metal
could leach out from the zeolite pore.Leaching experiment for
hydroxylation of phenol performed using OV–Y catalyst as a
representative catalyst.The catalyst was recovered by filtration,
regenerated by soxhlet extraction (MeCN),dried at 150℃ for 6 h

which may be due to leaching of the remaining metal ions on the
surface.Leaching was lowered markedly after the first reuse and
almost stopped after the second cycle.The % conversion was
lowered by 2–3% but reserved its selectivity (Fig.8).
It is of interest to know whether the ion-exchanged metal
could leach out from the zeolite pore.

hydroxylation of phenol performed using OV–Y catalyst as a
representative catalyst.
关于苯酚的羟基化作用的过滤试验是用催化剂做的,催化剂就用OV–Y作为一种代表性的催化剂.
The catalyst was recovered by filtration,
regenerated by soxhlet extraction (MeCN),dried at 150℃ for 6 h
and reused several times.
催化剂是用过滤来进行恢复的(恢复的目的是再使用),是用索氏萃取法生成的,在150℃干燥6小时,然后可以重新用几次.
It was found that the metal leached \2~2%
which may be due to leaching of the remaining metal ions on the
surface.
发现了过滤的金属 \2~2%(这里 \2符号我不知道什么意思,没法翻译),这可能是由于表面存留的金属离子导致的.
Leaching was lowered markedly after the first reuse and
almost stopped after the second cycle.
在第一次重复使用之后,过滤就明显降低了,并且在第二次循环使用之后就几乎停止了.
The % conversion was
lowered by 2–3% but reserved its selectivity (Fig.8).
转换的百分比低了2-3%,但是选择性是没有变化的(如图8).
