Filed: 1929-09-13
Abstract: 339,371. Johnson, J. Y., (1. G. Farbenindustrie Akt.-Ges.). Sept. 13, 1929. Cyanates and cyanamides are prepared by heating urea with oxides or carbonates of divalent metals especially the alkaline earth metals including magnesium and metals above mercury in the electromotive series of the elements, such as zinc, cadmium, copper, nickel, and lead. At temperatures between 130 and 400‹ C. mainly cyanates are obtained, above 400‹ C., cyanamides. Instead of urea a mixture of ammonia and carbon dioxide, either gaseous, liquid or solid, and preferably in the proportions by volume of 2 to 1, or ammonium carbonate or carbamate, with addition of ammonia if desired, may be used at a pressure of at least 50 atmospheres. The cyanates formed by heating to 130-400‹ C. are converted into cyanamides on further heating to say 600-700‹ C. More than one, and preferably two or more molecular proportions of urea or its constituents, must be present to each molecular proportion of metal oxide or carbonate. To remove the water formed in the above reactions a current of gas, which in the preparation of cyanamides is preferably free from oxygen, such as nitrogen or ammonia, may be passed over the reaction mixture, or part of the ammonia and carbon dioxide may be allowed to escape. The products of the pressure reaction may be freed from any volatile ammonium compounds by heating at ordinary or reduced pressure or by releasing the pressure in the reaction vessel at elevated temperatures such as 60-80‹ C. The evolved gases may be freed from water and ammonium carbonate and used agam. Specification 326,117 is referred to.
