Yield:6387-89-9 92%
Reaction Conditions:
with dihydrogen peroxide;sodium oxalate;oxalic acid;C18H42Mn2N6O3(2+)*2F6P(2-)*H2O in water; pH=3.5 - 3.6 at 4; for 0.5 h;Product distribution / selectivity;
Steps:
4
Epoxidation of allyl acetate was carried out in the manner of Example 1, however, with a variation in catalyst amount. This example illustrates that increased amounts of catalyst leads to increased production of epoxides; hence it is possible to decrease the time period. In the best experiment, allyl acetate was converted at 92% yield into glycidyl acetate (GlAc) in 0.5 hours at 95% efficiency. The results are included in the following Table.
