Electric Literature of 1558-82-3,Some common heterocyclic compound, 1558-82-3, name is Ethyl N-cyanoacetimidate, molecular formula is C5H8N2O, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
the last step into the reactor material, heated to 75 ,Add 520kgCyanoethyl ester, Dropping 5 hours, dropping temperature at this temperature for 4 hours, and then cooled to room temperature, filtered to give acetamiprid, and then dried to obtain the finished product 995kg, content of 99%Yield 96%.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route Ethyl N-cyanoacetimidate, its application will become more common.
