| abstract | Alkyl alkenyl ethers are prepared by contacting a terminal olefine with a substantially anhydrous solution of a salt or co-ordination compound of palladium, said solution containing an alcohol, and removing the alkyl alkenyl ether from the reaction zone immediately upon formation. Up to 10% by weight of water may be tolerated in the reaction mixture. Specified olefines are ethylene, propylene and butene-1; specified alcohols are methanol, ethanol, isopropanol and t-butanol. The palladium compound may be palladous chloride or acetate, lithium or sodium chloropalladite, dichloro bis-(benzonitrile) palladium (II) or allyl palladous chloride. The co-ordination compounds of palladium may be formed in situ. The palladium compound may be dissolved in an excess of olefine, if this is liquid, or in a polar or nonpolar solvent, e.g. benzene, acetic acid, dimethylacetamide, benzonitrile and acetonitrile. It is preferred to maintain the concentration of the alcohol in the reaction solution at a low level, e.g. less than 2 mols./litre reaction solution. The reaction may be effected at temperatures and pressures up to 300 DEG C. and 100 atmospheres. The ether may be removed from the reaction zone by distillation, optionally with the aid of entrainment in a stream of the olefin, if this is gaseous. Examples relate to the preparation of methyl vinyl ether; some acetal is obtained as a by-product. |
