Unsaturated dinitriles are reacted with an aromatic compound such as benzene in the presence of a Lewis acid such as aluminum chloride to yield novel aralkylenedinitriles, such as 5-methyl-5-phenylnonanedinitrile and isomers thereof. The aralkylenedinitriles can be reduced to novel aralkylenediamines or novel cycloalkylalkylenediamines. Polymerization of the aralkylenediamines or cycloalkylalkylenediamines with polycarboxylic acids provides novel polyamides of tough, clear, colorless character.
不饱和二腈与芳香族化合物(如苯)在Lewis酸(如
氯化铝)的存在下反应,得到新型的芳基亚烷基二腈,如5-甲基-5-苯基
壬二腈及其异构体。这些芳基亚烷基二腈可以还原为新型的芳基亚烷基二胺或新型的环烷基亚烷基二胺。将这些芳基亚烷基二胺或环烷基亚烷基二胺与多
羧酸聚合,可以制备出具有坚韧、透明、无色特性的新型聚酰胺。
