    • The invention relates to an improved process for preparing triallyl cyanurate (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 other 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 are used per mole of cyanuric chloride, cyanuric chloride and acid acceptor are added simultaneously or successively to anhydrous or at least 50% by weight aqueous allyl alcohol, and the reaction is performed in one or more stages at a temperature in the range of −5 to +50° C.
    • 本发明涉及通过在碱金属酸受体的存在下和不存在除烯丙醇以外的有机溶剂的情况下使氰尿酰氯与烯丙醇反应制备三烯丙基氰脲酸酯(TAC)的改进方法。 根据本发明,当每摩尔氰尿酰氯使用3.9至6.0摩尔烯丙醇和3.0至3.2当量酸受体时,获得超过99%纯度的TAC,其APHA色数低于10,产率超过90% ,氰尿酰氯和酸受体同时或依次加入到无水或至少50重量%的烯丙基水溶液中,并且反应在-5至+ 50℃的温度下在一个或多个阶段进行。
