PURPOSE: To obtain a compound useful as a raw material for fertilizers, herbicides or nitrogen compounds by reacting carbon nitride with Mg or Zn or a halide thereof.
CONSTITUTION: Carbon nitride, having a layer structure and expressed by the formula [(C3N3)2 NxHy)] (2≤(x)≤4; 0≤(y)≤8) is reacted with a compound expressed by the formula M or MX2 (M is Mg or Zn; X is halogen) at a temperature within the range of 600-1000°C to afford Mg or Zn carbonitride. The carbon nitride which is the raw material is obtained by reacting cyanuric chloride with ammonia and then thermally decomposing the resultant reaction product at about 400-600°C, etc. The aforementioned compound is a carbonitride expressed by the formula MgCN2 or ZnCN2 at 2:1 ratio of nitrogen to carbon.
