Abstract Process for the production of cyanamide The present invention provides a process for the production of cyanamide from urea and/or decomposition products thereof at an elevated temperature with the use of a microporous catalyst, wherein, as catalyst, there is used a zeolite and/or a silicoalumophosphate which is doped with transition metal cations selected from the Group IB and VIIB of the Periodic System. In this way, it is possible to increase the conversion, referred to urea, to 60 to 100%, the selectivity with regard to cyanamide thereby being from about 30 to 50% and with regard to the undesired melamine being ? 2%,
