摘要
以中间体(N,N,N’,N’-四丙酸甲酯-1,4-苯二胺)、1,2,2,6,6-五甲基哌啶醇为原料,在四异丙基钛酸酯为催化剂的条件下,通过酯交换反应合成了一种未见文献报道的高度对称的树枝状结构的化合物—新型防老剂(N,N,N’N’-[1,4苯二胺]-丙酸[1,2,2,6,6]-五甲基]哌啶醇酯)。产物的结构通过红外(FT-IR)、液相色谱-质谱(LC-MS)、元素分析及核磁(1 HNMR)等确定。为了研究新型防老剂的性能,实验将合成的新型防老剂、防老剂D(N-苯基-β-萘胺)、光稳定剂GW-622分别添加到天然橡胶中制成胶片,对其进行抗热氧老化性能和耐紫外光老化性能测试。结果表明合成的新型防老剂具有良好的抗热氧老化性能和耐紫外光老化性能。
A highly symmetric multi-branched compound（new antioxidant） N,N,N＇,N＇-[ 1,4 phenylenediamine]-propionate [1,2,2,6,6-pentamethyl ] piperidine alcohol ester which has not been reported in the literature,has been synthesized by transesterification using N,N,N＇N＇-tetra methyl propionate-1,4-phenylenediamine and 1,2,2,6,6-pentamethyl-4-ol as starting materials,and tetraisopropyl orthotitanate as catalyst.The structure of the compound was confirmed by 1H NMR,liquid-mass spectrometry test（LC-MS）,infrared spectrum test（FT-IR）,and elemental analysis.In order to study the properties of the new antioxidant,the new antioxidant,antioxidant D（N-phenyl-β-naphthylamine）,light stabilizer GW-622 were added to the natural rubber,and made a kind of different rubber diaphragms,and the properties of masterbatch thermooxidative,photooxidative were also determined.The results indicated that,the new antioxidant has good properties of masterbatch thermooxidative and photooxidative.
