Product D (required product) and by-product E (impurity), major and minor reaction is strong exothermal reaction, and reaction equation is as follows：
Main reaction：
Side reaction：
Add in addition to control catalyst C dosages, control reactor characterisitic parameter (temperature, pressure etc.) in above-mentioned Chemical Manufacture
Outside fast response rate, or even higher D products reaction conversion ratio can be also obtained using the excessive technique of raw material A and (refers to technique
Match A:B:C is 9:3:1), therefore rationally adjusting raw material A, B ratios and catalyst C dosages are extremely important.Above-mentioned work production reaction
Device mathematical model part index number parameter is as shown in table 1.
1 reactor index parameter of table
Analysis is found：There are problems that cut-throat competition in reaction process between main reaction and side reaction, it can be seen that main reaction
Activation energy is less than side reaction activation energy (side reaction activation energy is 2.32 times of main reaction activation energy), and main reaction pre-exponential factor is more than
Side reaction pre-exponential factor, main reaction heat release are more than side reaction heat release.
According to the above-mentioned Chemical Manufacture of activation energy correlation analysis, main reaction activation energy is less than side reaction activation energy, promotes temperature
When accelerating reaction rate, the velocity coefficient of side reaction increases bigger.In reaction process, reaction temperature is promoted to main reaction rapidly
Temperature condition, be conducive to improve reaction rate, increase product accumulation, improve yield.Initial temperature-rise period production concentration compared with
Low, this stage, activation energy was analysis shows this stage side reaction is more sensitive to temperature mainly to be promoted based on reaction temperature.Initially

60 DEG C of heatings are very fast (about 163s).When analysis can determine about 45 DEG C, the reaction rate of main reaction is obviously accelerated, and temperature is may be set to
Spend segmentation condition.
It is tested on reactor Semi-physical model according to segmented feed process, only change catalyst C during this
Dosage.The influence that experiment mainly reacts different phase by measuring different catalysts dosage, it is opposite to measure catalyst
Optimal dosage, when will heat up the division points of stage and the stage of reaction to be set in temperature of reactor being 45 DEG C.Experimental data such as table 3
