摘要: The invention relates to a method of producing cyanuric chloride by trimerizing chlorocyan at a temperature of at least 250° C. on washed activated carbon as the catalyst. The service life of the catalyst can be improved by using an activated coal with an effective pore volume V eff of equal or greater 0.17 ml/g, with V eff being the result of pores with a pore diameter ranging from 0.5 to 7 nm.
