Abstract:
The application relates to compositions comprising di-fatty-alkyl or -alkenyl polyalkylamines of the general formula (I) or (II), to a process for their preparation which involves a cyanoethylation step and a hydrogenation step, and their use as demulsifiers for oil-in-water emulsions, corrosion inhibitor, fuel additive, anti-scaling agent, asphalt additive, enhanced oil recovery agent for oil-wells, cutting-oil additive, and anti-static agent. The product show good performance combined with a favourable viscosity profile.

Claim (Index 10):
A process for making the polyalkylamines compositions of  claim 1  wherein a di-fatty-alkyl(ene) alkyldiamine is subjected to a cyanoethylation step and a subsequent hydrogenation step, whereby in the cyanoethylation step at least 2 mole of acrylonitrile is used per mole of di-fatty-alkyl(ene) alkyldiamine and an acidic catalyst is used.
