This invention provides aromatic diimines which have imino hydrocarbylidene groups with at least two carbon atoms, and aromatic secondary diamines which have amino hydrocarbyl groups with at least two carbon atoms. Both the aromatic diimines and the aromatic secondary diamines either are in the form of one phenyl ring, or are in the form of two phenyl rings connected by an alkylene bridge; each position ortho to an imino group or an amino group bears a hydrocarbyl group. When in the form of one phenyl ring, there are two imino groups on the ring or two amino groups on the ring; the imino groups or amino groups are meta or para relative to each other. When in the form of two phenyl rings connected by an alkylene bridge, there is either one imino group or one amino group on each phenyl ring. Also provided are processes for forming diimines and secondary diamines.
这项发明提供了具有至少两个碳原子的亚烷基亚胺基团的芳香二亚胺和具有至少两个碳原子的氨基亚烷基团的芳香二胺。这些芳香二亚胺和芳香二胺可以是一个苯环的形式,也可以是由烷基桥连接的两个苯环的形式;每个邻位对着亚烷基基团或氨基基团。当以一个苯环的形式时,环上有两个亚胺基团或两个氨基团;亚胺基团或氨基团互为间位或对位。当以由烷基桥连接的两个苯环的形式时,每个苯环上要么有一个亚胺基团,要么有一个氨基基团。还提供了形成二亚胺和二胺的方法。
