Page/Page column 35; 40; 41; 43, (2019/02/25)
The present invention relates to a process to prepare propylene amines of the formula NH2-(A-NH-)pR, wherein R is a hydrogen atom or an alkyl group, p is at least 1 when R is an alkyl group, and at least 2 when R is a hydrogen atom, or derivatives or precursors thereof wherein one or more units -NH-A-NH-may be present as a cyclic urea unit. (I) or a cyclic unit (ll) or between two units –NH-A-NH-a carbonyl bond is present, each unit –A-can be independently an alkylene unit and at least one unit –A-is a -C3H6- unit, wherein each -C3H6- unit can be linear or branched, by reacting (i) at least one of a hydroxy-functional compound chosen from the alkanolamine-functional compounds, and dihydroxyalkylene compounds, with (ii) an amine-functional compound,in the presence of (iii) a carbon oxide delivering agent, wherein at least one of the alkanolamine-functional compound, the amine-functional compound and/or the carbon oxide delivering agent contains at least one alkylene unit (A) that is a propylene unit

Paragraph 0119-0124, (2016/11/09)
The present invention relates to 2-N,N-(bis-2-aminoalkyl)-1,2-alkyldiamine derivatives of formula (I) as such, to a process for preparing the 2-N,N-(bis-2-aminoalkyl)-1,2-alkyldiamine derivatives, to the use of the 2-N,N-(bis-2-aminoalkyl)-1,2-alkyldiamine derivatives as hardeners for epoxy resins, as an intermediate in the preparation of triisocyanates, as initiators for polyetherols and/or as monomers for the preparation of polyamides, to triisocyanates derived from the 2-N,N-(bis-2-aminoalkyl)-1,2-alkyldiamine derivatives of formula (I) and also to a process for preparing these triisocyanates.
