In thediisopropanolamine products which are manufactured by adopting the method, the component of 1, 1<1>-nitrousalkyl-dipropyl-2-alcohol accounts for more than 99 percent (hereinafter referred to as mass percent), and the isomeride thereof is less than 1 percent. In addition, the cost of the production operation in the method is less, the production cost is low, the product quality is high, and the high-end requirement of products such as synthetic medicine, farm insecticide, etc. is satisfied.
