Ethylenimines

APO. Research on ethylenimine [151 -56-4] led to the development of tris(azitidinyl) phosphine oxide [545-55-1] (APO) as a flame retardant for...

A process for the production of ethylenimine [151 -56-4] a suspect carcinogen, by the vapor phase dehydration of monoethanol amine has been developed (128—132). By using an alkyleneamine co-feed with the alkan olamine, higher alkylene amines are made in situ (133). The catalysts are tungsten-, niobium-, or phosphate-based.

The secondary amines used in the preparation of enamines have been primarily simple dialkylamines or cyclic amines of five- or higher-membered rings. Azetidine (4) yields a stable enamine with cyclopentanone (28). No simple enamines formed by condensation of ethylenimine (5) or a substituted ethylenimine with an aldehyde or ketone have been reported. 

A solution of 30.3 parts of triethylamine and 12.9 parts of ethylenimine in 180 parts of dry benzene is treated with a solution of 16.9 parts of thiophosphoryl chloride in 90 parts of dry benzene at 5°C to 10°C. Triethylamine hydrochloride is filtered off. The benzene solvent is distilled from the filtrate under reduced pressure and the resulting crude product is recrystallized from petroleum ether. The N,N, N"-triethylenethiophosphoramide had a melting point of 51.5°C.

Ring-opening polymerization of 2-methyl-2-oxazoline produces poly( V-acetyl-ethylenimine) (Scheme 2) [24-27], The resulting polymer can be regarded as a... 

Copolymers of carbon monoxide, carbon dioxide, sulfur dioxide or carbon disulfide are frequently formed in combination with oxiranes, thiiranes or aziridines. Copolymerization of carbon monoxide and ethylenimine was carried out under radiation and the formation of 3-nylon was observed238. ... 

In the ethylene atmosphere, carbon monoxide and ethylenimine copolymerized with a radical initiator to form a terpolymer239. The following radical mechanism may be proposed ... 

Ethylenimine is known to spontaneously form copolymers with /3-propiolactone274) or cyclic imides275). Crystalline copolyamides of alternating structure were obtained with the latter monomer. 

Grafting of 2-methyloxazoline onto chloromethylated polystyrene beads in benzonitrile at 110 °C gave graft copolymers, which were hydrolyzed to poly(styrene-g-ethylenimine) and useful as a chelating resin370. ...
