摘　　要：以二苯胺为原料,二甲氨基吡啶为催化剂,与固体光气经过缩合反应得到二苯基氨基甲酰氯,再与甲胺反应,合成安定剂N'-甲基-N,N-二苯脲(AK-Ⅱ)。通过红外分析、核磁共振、元素分析等手段鉴定了其结构。讨论了反应介质、时间、催化剂对一次缩合收率的影响,反应介质乙醚,时间4 h,催化剂二甲氨基吡啶,收率95%。并用真空安定性法测试了AK-Ⅱ与推进剂主要组分的相容性。结果表明,AK-Ⅱ与吸收药(NC+NG)、硝基胍(NQ)、黑索今(RDX)、铝粉(Al)、高氯酸铵(AP)、端羟基聚丁二烯(HTPB)、奥克托今(HMX)、甲苯二异氰酸酯(TDI)、三醋精(TA)、含能粘合剂(BAMO-THF)、固化剂(N-100)的相容性良好。Diphenylcarbamylchloride was prepared by condensation reaction in the presence of a catalyst with dimethylaminopyridine and diphenyl amine as primary materials.The title compounds N'-methyl-N,N-diphenylurea(AK-Ⅱ)was obtained by diphenyl-carbamylchloride reacted with methyl amine.Their structures were confirmed by IR,NMR and element analysis.The effect of solvent,time and catalyst on above mentioned reactions was studied.The optimum reaction conditions are:diethyl ether as dissolvent,reaction time 4 h and dimethylaminopyridine as catalyst,the yield of 95%.The compatibility of AK-Ⅱwith main components of propellants were studied by VST experiment,the result show that AK-Ⅱhas good compatibility with NC+NG,NQ,RDX,Al,AP,HTPB,HMX,TDI,TA,BAMO-THF and N-100.
