Liquid distributor and precipitation reaction synthesis method

The invention relates to the field of distributors of two types of liquid, and discloses a liquid distributor and a precipitation reaction synthesis method. The liquid distributor comprises a middle disc provided with a plurality of first distribution holes, an outer disc provided with a plurality of second distribution holes, a first raw material inlet formed in the middle disc, and a second rawmaterial inlet formed in the outer disc; and the position relationship between the first distribution holes and the second distribution holes meets the following conditions that (I) projection areas of the multiple second distribution holes on the horizontal plane and projection areas of the multiple first distribution holes on the horizontal plane are arrayed in a staggered mode, and (II) in projection on the horizontal plane, each first distribution hole is adjacent to the two or more corresponding second distribution holes. Through the liquid distributor, it can be ensured that the two types of liquid do not make c
