The invention relates to an improved process for preparing triallyl cyanu rate (TAC) by reacting cyanuric chloride with allyl alcohol in the presence of an alkali metal acid acceptor and in the absence of an organic solvent ot her than allyl alcohol. According to the invention, TAC is obtained in over 99% purity with an APHA colour number below 10 in a yield of over 90% when 3 .9 to 6.0 mol of allyl alcohol and 3.0 to 3.2 equivalents of acid acceptor a re used per mole of cyanuric chloride, cyanuric chloride and acid acceptor a re added simultaneously or successively to anhydrous or at least 50% by weig ht aqueous allyl alcohol, and the reaction is performed in one or more stage s at a temperature in the range of -5 to +50°C.
