Abstract: b -Chloroalkyl ethers of the formula wherein R1 is hydrogen or an alkyl, alkenyl, alkoxyalkyl or aralkyl radical, R2 is hydrogen or an alkyl, alkoxyalkyl, aryl or aralkyl radical or the two R2 radicals may form a common alkylene chain of 3 to 10 carbon atoms, optionally with 1 or 2 double bonds, and R3 is an alkyl, cycloalkyl or aralkyl radical, R1, R2 and R3 being optionally substituted, e.g. by halogen atoms or alkoxy radicals, are obtained by reacting olefins of the formula R1R2C=CR1R2 with chlorine and alcohols of the formula R3OH under anhydrous conditions in the presence of an acid-combining agent which reacts with hydrogen chloride without the production of water. Suitable acid-combining agents are the alkali-metal alcoholates and the mono- and poly-epoxides. Olefin dichlorides of the formula R1R2ClC-CR1R2Cl may be produced as by-products.
