Orthogonal Experiment on Engineering Factors

Several chemical engineering factors affect the biphasic hydroformylation of 1-dodecene in a gas-hquid-Hquid three-phase reachon system. In previous research [1], effects of temperature, total pressure, H2/CO molar raho, catalyst and ligand concentration, olefin concentration, surfactant concentration, and organic/ aqueous-phase volume ratio on the hydroformylation kinetics were studied with 

The margin analysis based on the experimental results in Table 2 suggests that the most important factor investigated is the agitation speed N and the second most important is the Vq/ w r ho, as far as the maximum initial reaction rate, normaljiso aldehyde ratio and conversion are concerned (Table 3). The effect of surfactant concentration was the least important in the selected range of reaction 

Although the optimal set of variable levels corresponding to each index was not completely coincident, the optimal reaction conditions for a compromise between
