ABSTRACT:
Monoalkylethers of alkyleneglycols and oligoalkyleneglycols are reacted completely with terminally unsaturated alkenyl halides to form terminally mono unsaturated glycolethers as product, wherein initially a complete reaction to the corresponding alcoholate takes place with only one equivalent of alcoholate former, such as alkali metal alcoholate or hydroxide, and two equivalents of glycolmonoether, then the alcoholate is reacted with one equivalent of alkenyl halide, whereupon a mixture of the desired product and the glycolmonoether of the alkali metal halide is filtered or distilled off, then this mixture is reacted with the second equivalent of the alcoholate former, whereupon the recovery of the product takes place by distillation from the reaction mixture and then, after addition of a further equivalent of glycolmonoether to the residue from the product recovery, the reaction of the first and the subsequent steps is repeated.
