Abstract (English):
The influence of beginning batching up molybdenum metal powder in the preparation catalytic molybdenum complex on its dissolved forms accumulation in the mixed of ethanol and oxidized ethylbenzene has recognized. Found that the beginning MMP portion taken of 0,45% by weigh of the complex solvent has fully dissolved. Increasing the starting weight of MMP has increased the dissolved form of molybdenum and undissolved bottom fraction of molybdenum powder. Shown that the highest activity and selectivity in the process of epoxidation olefins has been solution not containing bottom fraction of Mo.
