摘　　要：介绍了氢氧化钾催化法(一步法)和双金属络合物催化法(DMC法、两步法)生产聚醚二醇BH-210工艺。对两种生产工艺进行了探讨,并对两种生产工艺的优缺点进行了总结比较,特别介绍了DMC的添加量对聚醚二醇生产的影响。Details of the catalytic method of potassium hydroxide （ also known as single-step） and bimetallic complex catalysis （also known as two-step） production process of polyether glycol BH-210 were described. The two kinds of production technology were discussed, and the advantages and disadvantages of the two kinds of production processes were summarized. The influence of DMC dosage on the production of the polyether diol was introduced es- pecially.
