Detailed Description

The present invention will be further explained with reference to the drawings and examples.

Example 1

Referring to fig. 1 to 2, the impurity removing device for the diethyltoluenediamine stock solution comprises a tank body 6, wherein a longitudinal transparent observation window 4 is arranged on the tank body 6.

The middle part in the cavity of the tank body 6 is provided with a baffle 15 which is arranged in an inclined way, and the cavity of the tank body 6 is divided into an upper reaction bin 14 and a lower clear liquid bin 16 by the baffle 15.
