The investigation of the catalytic activity and stereoselectivity of ligand 10 was also carried out under another standard set of K〓Fe 〓 conditions (〓/ligand/substrate=0.002: 0.01: 1). The AD reaction of seven olefins gave corresponding diols in 72～99% yield (except for ethyl cinnamate, 48%) and 91～99% ees, which was comparable to those obtained from the reactions using the commercial ligand 〓PHAL.

The observational and calculated results are well matched. The calculated mean diameter, mean square-root diameter, mean cube -root diameter and liquid water content are all well matched with the observational results; In the paper two examples have been analyzed by using the seeding region data and the possible affecting region data in leeward region. It is found that F-100, 2dc, and 2dp's particle concentrations increase in leeward region, but rising extent is different, which is likely to be due to difference of seeding effect time.

The results show that the decalescence of catalyst bed affects the process of hydrogen peroxide catalytic decomposition greatly. If the catalyst bed is preheated or made up of materials with low thermal conductivity, that influence can be depressed. At the same time, the response characteristic of catalyst bed and the efficiency of catalytic decomposition can be improved. The low frequency pressure instability of catalyst bed occurs because of the coupling of catalytic decomposition and supplying. The decomposition plane pushes all the way through the catalyst bed during pressure oscillations, causing unreacted liquid hydrogen peroxide to be exhausted from the bed and leading to the appearance of liquid hydrogen peroxide channeling. Consequently, how to prevent or at least limit this channeling is the key to eliminate the pressure instability of catalyst bed. It was found that adding clapboard to the catalyst bed can depress the pressure instability efficiently.
