摘要 |
In the novel process alkylene glycol monoalkyl ethers of the formula <IMAGE> in which R1 is an alkyl radical having 1 to 25 carbon atoms, R2 is H, CH3 or C2H5 and, within the chain of the polyoxyalkylene radical, arranged randomly or in blocks, can also assume all three meanings, R3 is CH3 or C2H5 and n denotes 1 to 100, are hydrogenated to give the corresponding alkylene glycol dialkyl ethers in the presence of a supported nickel catalyst using hydrogen without pressure. |
