Seasonable that 1- octene is added, reaction time 120min, remaining experiment condition is constant, and test result is shown in Table 1.
Table 1
" --- " indicates not detect.
It can be seen that the reaction temperature different by two stages of setting, the conversion ratio and product of raw material from the data of table 1
Yield increase significantly compared to being reacted at single temperature.From comparative example 1 and embodiment 1 and comparative example 2 and embodiment 4
Comparison can be seen that and directly reacted at high temperature using catalyst, catalyst activity and selectivity are lower.From comparative example 3
Comparison with embodiment 1 can be seen that individually by catalyst system carry out pre-reaction after, catalyst activity and selectivity compared with
It is low.
Using method provided by the invention, catalyst recycling still has good catalytic effect when reusing, and obtains
The conversion ratio of octene and the selectivity of aldehyde C-9 be held in higher level.
It should be noted that embodiment described above for explaining only the invention, is not constituted to of the invention any
Limitation.By referring to exemplary embodiments, invention has been described, it should be appreciated that word used in it is descriptive
With explanatory vocabulary, rather than limited vocabulary.The present invention can be made within the scope of the claims by regulation
Modification, and the present invention is revised in without departing substantially from scope and spirit of the present invention.Although the present invention described in it relates to
And specific method, material and embodiment, it is not intended that the present invention is limited to particular case disclosed in it, on the contrary, this hair
It is bright to can be extended to other all methods and applications with the same function.
