远在1838年,比内奥(Bineau)将氨及氯化氰在乙醚中作用,得到一种结晶体,他称之为氯代氰化铵。十三年后克洛依茲(Cloez)和康尼扎罗(Cannizzaro)証明这种所谓氯代氰化铵的物质,实质上是氯化铵和一个新化合物的混合体,这个新化合物他們称之为氰氨: CNCl+2NH_3→NH(?)Cl+H_2NCN 此后氰氨之引起广泛的注意,不仅因为它具有二个活波的基团(氨基及氰基),可以进行许多化学反应,而且它已经直接地或间接地成为主要的化工原料。譬如氰氨化钙,在鋼铁工业中用它作为鉄的去硫剂、鋼的加氮剂。在农业中,它是混合肥料的主要成份,也是
As far back as 1838, Bineau reacted with ammonia and cyanogen chloride in diethyl ether to give a crystal, which he called ammonium chlorohydrinate. Thirteen years later Cloez and Cannizzaro proved that this so-called ammonium cyanohalide is essentially a mixture of ammonium chloride and a new compound, which they claim Cyanamides: CNCl + 2NH_3 → NH (?) Cl + H_2NCN Cyanoamines have drawn much attention since then, not only because they have two active-wave groups (amino and cyano) and can undergo many chemical reactions, and It has become the main chemical raw material directly or indirectly. Cyanamid, for example, is used as a desulfurizing agent in steel industry, as a nitrogen-adding agent for steel. In agriculture, it is the main ingredient of compost, too
