Patent

CA 2602352

This invention provides aromatic diimines where the diimines have imino groups with at least two carbon atoms, and either are in the form of one benzene ring having two imino groups on the ring, which imino groups are meta or para relative to each other, and in which each position ortho to an imino group bears a hydrocarbyl group, or are in the form of two benzene rings connected by an alkylene bridge and having one imino group on each ring, and in which each position ortho to an imino group bears a hydrocarbyl group. This invention also provides aromatic secondary diamines where the diamines have amino hydrocarbyl groups with at least two carbon atoms, and either are in the form of one benzene ring having two amino groups on the ring, which amino groups are meta or para relative to each other, and in which each position ortho to an amino group bears a hydrocarbyl group, or are in the form of two benzene rings connected by an alkylene bridge and having one amino group on each ring, and in which each position ortho to an amino group bears a hydrocarbyl group. Also provided are processes for forming diimines and secondary diamines from primary diamines, including the aromatic diimines and aromatic secondary diamines of the invention.

Cette invention concerne des diimines aromatiques, lesdites diimines ayant des groupes imino ayant au moins deux atomes de carbone et étant soit sous la forme d'un noyau benzénique ayant deux groupes imino sur le noyau, lesquels groupes imino étant en position méta ou para l'un par rapport à l'autre et chacune des positions ortho par rapport à un groupe imino portant un groupe hydrocarbyle, soit sous la forme de deux noyaux benzéniques reliés par un pont alkylène et ayant un groupe imino sur chaque noyau, chaque position ortho par rapport à un groupe imino portant un groupe hydrocarbyle. Cette invention concerne également des diamines secondaires aromatiques, lesdites diamines ayant des groupes aminohydrocarbyles ayant au moins deux atomes de carbone et étant soit sous la forme d'un noyau benzénique ayant deux groupes amino sur le noyau, lesquels groupes amino étant en position méta ou para l'un par rapport à l'autre et chacune des positions ortho par rapport à un groupe amino portant un groupe hydrocarbyle, soit sous la forme de deux noyaux benzéniques reliés par un pont alkylène et ayant un groupe amino sur chaque noyau, chaque position ortho par rapport à un groupe amino portant un groupe hydrocarbyle. L'invention concerne également des procédés servant à former des diimines et diamines secondaires à partir de diamines primaires, comprenant les diimines aromatiques et diamines secondaires aromatiques de l'invention.
