epoxidation catalytic systems research
Epoxy cyclohexane is epoxy cures, is a kind of important intermediates, application range is very wide. Currently in pharmaceutical, pesticide, coating industry more than ten months is widely used.
Using hydrogen peroxide industrial oxidation method, the method of using a bigger toxicity solvents, environmental pollution, Epoxy cyclohexane easily hydrolyzed part of technical problems, H2O2 itself to decompose, Two mutually dissolved or not, reaction efficiency, etc.
To solve these problems, this paper mainly from the following several aspects are discussed and studied:
1) adopting two-step, research synthesis (4) porphyrin manganese processing conditions, four phenyl porphyrin manganese maximum yield of reaction conditions,
2) porphyrin manganese activation H2O2 catalytic epoxidation system (research, explore the optimum reaction conditions. And validation porphyrin manganese catalytic activity.
3) NaHCO3 activation H2O2 catalytic epoxidation system (research, the optimization of process conditions, the hydrogen peroxide utilization.
4) porphyrin manganese and NaHCO3 mixture (catalytic epoxidation system research, to explore the reaction.
In obtained through experiments, the following conclusions:
The 1) was synthesized by different methods (4) porphyrin manganese, and through ir spectra in our experiments of their structure. For four phenyl porphyrins and four phenyl porphyrin manganese synthesis conditions made some improvements, further improve their yield.
2) in TX - 100 grants, NaHCO3 activation H2O2 solvent (catalytic epoxidation, have higher yield.
3) to find a better technology conditions: (5 mL, porphyrins manganese 0.1 g, sodium bicarbonate 0.6 g, imidazole 0.11-100 g, TX, 30 % of 0.5 g 22 g, hydrogen peroxide, cold bath temperature control in 27 degrees 8h reaction. The yield of the epoxy cyclohexane 74.
