双氨基苯硫酚类化合物,其合成方法及其应用
本发明涉及一种双氨基苯硫酚化合物,特别是涉及有效地用作以腈基作为交联基团的含氟弹性体的固化试剂的双氨基苯硫酚。
下面这些双氨基苯硫酚类化合物是已知的并用作为耐热树脂聚苯并噻唑化合物等的原料。
Figure C9511972800051
本发明的目的是制备一种新的双氨基苯硫酚类化合物。它能有效地作为固化剂应用于以腈基作交联基团的含氟弹性体中。
根据本发明所提供的这种新的双氨基苯硫酚类化合物可用下面的通式[I]表示:
Figure C9511972800061
其中Rf是一个从C1到C10的全氟亚烷基(perfluoroalkylidene)。它可以盐的形式存在,比如盐酸盐,氢溴酸盐,硫酸盐,硼酸盐,羧酸盐等。
本发明中的双氨基苯硫酚类化合物可由以下一系列步骤合成:[III]-[II]的反应:在室温和搅拌下将溴的冰醋酸溶液滴加到双氨基苯基化合物[III]和碱金属的硫氰酸盐(其量超过双氨基苯基化合物[III]等摩尔量)的醋酸溶液中,这些硫氰酸盐可以是硫氰酸钠或硫氰酸钾。接着向其中加入水,将混和物加热到沸点,然后冷却过滤,将碳酸氢钠加入滤液中得到沉淀,即为双氨基苯并噻唑化合物[II]。反应机理可能是溴为氧化剂使硫氰酸根和芳环加成,接着氰硫基和氨基发生亲核环合反应
一般使用的双氨基苯基化合物[III]是2,2-双(4-氨基苯基)六氟丙烷。1,2-双(4-氨基苯基)四氟乙烷等也可使用。
[II]→[I]的反应
将此得到的双氨基苯并噻唑化合物[III]在约110℃到130℃,惰性气氛下加入到碱金属的氢氧化物(如氢氧化钠或氢氧化钾)水溶液中,然后将混合物慢慢升温到约260℃使反应进行,直到不产生氨为止。接着将温度降到约200℃。加入水后,使反应物冷却到室温,用无机酸如浓盐酸的稀水溶液加入反应混合物中,调节pH至6,最后加入冰醋酸到得到沉淀,为双氨基苯硫酚化合物(I)。
所获得的双氨基苯硫酚化合物及其盐可作为固化剂用于以氰基为交联基的含氟弹性体中。
用于本发明的含氟弹性体包括一种四氟乙烯、全氟(低级烷基乙烯基醚)或全氟(低级烷氧基-低级烷基乙烯基醚)和少量(即以三元共聚物计摩尔含量为0.1到5%)全氟不饱和腈化合物的三元共聚物。
全氟不饱和腈包括例如以下化合物:CF2=CFO(CF2)nOCF(CF3)CN             (n:2~5)CF2=CF[OCF2CF(CF3)]nO(CF2)mCN      (n:1~2,m:1~4)CF2=CF[OCF2CF(CF3)]nCN              (n:1~5)CF2=CFO(CF2)nCN                       (n:1~10)
按重量计,以大约0.1到5份,最好是约1到3份双氨基苯硫酚化合物作为固化剂加到100份以CN基作交联基团的含氟弹性体中,这种可交联基团是由全氟不饱和腈化合物通过共聚作用而提供的。除了双氨基苯硫酚外该全氟弹性体还可容纳一些必须的添加剂,比如填料,增强剂,稳定剂,增塑剂,润滑剂,加工助剂等。将混和物放入轧制机或其它类似装置中捏和,并在约160℃到250℃的条件下初级硫化(加压硫化)约30~60分钟,然后在约200~300℃下进行二次硫化(烘炉硫化)约10~50小时,最好在惰性气氛中进行。
根据本发明,可以提供一种新的双氨基苯硫酚化合物作为硫化剂,它可有效应用于以CN作交联基团的含氟弹性体中。
