METATHESIS METHOD FOR PURIFYING STARTING PRODUCTS

摘要

The invention relates to a method for producing a compound or a mixture of a non-aromatic C-C-double bond or C-C-triple bond compounds (compound A) from another compound or a mixture of other non-aromatic C-C-double bond or C-C-triple bond compounds (compound B) comprising I. a step (I) which consists in removing impurities from the compound (B) by bringing said impurities into contact with an adsorption agent containing at least 3 % by weight aluminium oxide and by activating them at temperatures ranging from 450 to 1000 °C (adsorption agent X) and II. a step (II) consisting in removing the impurities from the compound (B) according to the step (I) and in bringing said compound (B) into contact with a metathesis catalyst under usual conditions of a metathesis reaction.
