CATALYTIC COMPOSITION FOR PRODUCING ACRYLIC ACID ETHERS BY METATHESIS REACTION OF DIALKYLMALEATE WITH ETHYLENE Russian patent published in 2008 - IPC B01J31/02 B01J23/46 C07C6/00 C07C69/54 C07C67/317 

FIELD: chemistry.

SUBSTANCE: catalytic composition contains the catalyst of olefin metathesis as one component, and phenol derivatives as another component, at proportion: 1 mol equivalent of catalyst to 200-1500 mol equivalents of phenol derivatives. In another modification, the catalytic composition contains as the second component the alcohol derivates which do not contain the C-H fragments at α-position to hydroxyl function, at proportion: 1 mol equivalent of catalyst to 200-1500 mol equivalents of alcohol derivatives. Another one modification of the invention has quinine or its derivatives as the second component of the catalytic composition. Particularly, the ruthenium complex with formula can be used as a catalyst of olefin metathesis.

EFFECT: number of catalyst turnover and life-time of catalyst in metathesis reaction of dialkylmaleate with ethylene are increased.
