1. one kind by carrying out reaction-ure feeding in the liquid method of chemical reaction, said method comprising the steps of:

  • A) use the reactor that comprises hollow container and be arranged in the mixing component of described hollow container with inner and outer wall, described mixing component comprises the turning axle with top and bottom, described turning axle is suitable for installing in fact in vertical uppermost set of impellers with in fact in the lowermost set of impellers of bottom, and wherein said topmost and lowermost set of impellers comprise a plurality of blades with upper limb and lower edge;

    B) establish liquid enter in the described reactor to the described reactor level so that the described uppermost set of impellers of described mixing component be immersed in fact in the described liquid;

    WithC) at the feed entrance point that is arranged in the zone that is lower than described uppermost set of impellers just with reaction-ure feeding to described liquid, described zone is;

    I) upper limit of determining by line of and half height of pact by the uppermost set of impellers blade vertical in vertical direction with described axle with vertical with described axle and be positioned at from the low side of uppermost set of impellers blade extremely about 1/3 distance of the described lowermost set of impellers blade definite lower limit of line that is lower than the lower edge of described uppermost set of impellers blade determined, measure downwards from the described lower edge of described uppermost set of impellers blade;

    WithIi) radially determined with the inner loop-line of about 2/3 diameter that is positioned at the described uppermost set of impellers blade of measuring from the impeller outer end of described axial described uppermost set of impellers blade by being positioned at Section of Outer Ring Line from the tip of described uppermost set of impellers to the inwall of described reactor that measure about 0.1 times of container diameter from.
