摘要：
In the present invention, when polyoxyalkylene alkyl ethers are produced by adding propylene oxide to a linear alcohol in the presence of an alkali catalyst, the proportion of the alkali catalyst and the proportion of propylene oxide, per mole of active hydrogen of the linear alcohol, are in specific ranges respectively and the temperature in the addition between the linear alcohol and propylene oxide is in a specific range.
