FIELD: chemistry. ^ SUBSTANCE: based on chemical equation 3CCl4+4NH3 = C3N4+12HCl, quantities of carbon nitride C3N4 and carbon tetrachloride CCl4 are preliminary calculated. Then prescribed amount of liquid NH3, in sealed vessel, and carbon tetrachloride CCl4 are introduced into reaction chamber. The chamber is secured, within it the vessel with NH3 is opened, the chamber is heated to temperature 195-200° and let stand for 1.5-2 hours, till the reaction is finished and crystalline carbon nitride C3N4 is obtained. ^ EFFECT: method is economically effective, and time of synthesis is shortened. ^ 2 ex |
