- Process for producing substituted 1,11-diaminoundecanes
-
Diamines of the formula I STR1 wherein R1, R2, R3 and R4 have the meanings defined in claim 1, can be produced by a simple process comprising reacting 1-aza-1,5,9-cyclododecatrienes, correspondingly substituted

- Substituted 1,11-diaminoundecanes, processes for producing them, and their use
-
There are described novel substituted 1,11-diaminoundecanes, particularly those of the formula STR1 [R1 is alkyl having 1-12 C atoms, R2 is hydrogen or alkyl having 1-12 C atoms, R3 is alkyl having 1-12 C atoms, cycloalkyl having 4-12 C atoms, aralkyl having 7 or 8 C atoms, unsubstituted or substituted aryl, pyridyl, furyl or thienyl, R4 is hydrogen, alkyl having 1-12 C atoms, cycloalkyl having 4-12 C atoms, or unsubstituted or substituted aryl, or R1 and R2 and/or R3 and R4 together are alkylene having 3-11 C atoms], and processes for prducing them. The compound of the formula I can be used for example for producing polycondensation products, particularly polyamides. They can be used also as curing agents for epoxide resins.
